Coaches are the engine that drives RTB
One of our foundational beliefs is that coaches will only take care of players to the extent we take care of them. We believe good coaches can be found, but great coaches are developed.
RTB invests in our coaches with clear standards to lean on, a supportive team environment, and growing opportunities to impact more players every season.
Come meet the people behind RTB Volleyball. Passionate, experienced, and deeply invested in every athlete they coach.
Danny zambito
CEO & Co-Founder, RTB Volleyball
Club Director, RTB Chantilly
Asst. Club Director, RTB Manassas
Head Coach, RTB 14 Avalanche (RTB Manassas)
Coach Danny didn't come to volleyball through the traditional path. Watching his daughter grow through the sport, develop as a competitor, and become the athlete and person she is today ignited something in him. RTB Sports is the result of that inspiration, and coaching is where it lives every day.
On the court, Danny is energetic, positive, and relentlessly focused on getting the best out of the people in front of him. He coaches through encouragement rather than fear and builds culture before he builds skills. He believes deeply in the power of teamwork — that a group of people who trust each other, compete for each other, and hold each other accountable will always outperform any collection of individual talent. His greatest satisfaction as a coach comes from watching athletes break through barriers that have been holding them back — and seeing the look on their face when they realize they did it.
Danny currently serves as Head Freshman Coach at Centreville High School and is a longtime volunteer leader at SYA Volleyball, where he has served as a head coach and part of the program's leadership team — running the travel league, coordinating club programs, and leading camps and clinics throughout Northern Virginia for years.
Off the court, Danny is a seasoned senior executive with decades of experience leading complex, high-growth organizations — most recently as Chief Operating Officer of one of the world's largest legal technology companies. He brings that same discipline, intentionality, and people-first philosophy to every aspect of RTB.
Ms. Jen brings years of experience supporting both club and high school volleyball programs through organization, communication, and player-focused leadership. Since 2020, she has worked behind the scenes in club volleyball operations, helping manage scheduling, team logistics, family communication, tournament coordination, and day-to-day program support. She has also supported the Centreville High School Girls Volleyball program since 2021.
Jen is passionate about creating a positive and supportive environment for athletes and families while helping programs run smoothly and efficiently. Known for her attention to detail and strong communication skills, she believes successful volleyball programs are built on trust, consistency, organization, and strong relationships with players and parents alike.
At RTB Volleyball, Jen is focused on helping create a player-centric culture where athletes feel supported both on and off the court. Her goal is to ensure families feel informed, valued, and connected while helping provide the best possible experience for every player in the program.
When she's not helping support athletes and families in the volleyball community, Jen enjoys time with her family, her pets, and the everyday moments that matter most.

madi zambito
Co-Founder, RTB Volleyball
Asst. Coach, RTB 14 Avalanche (RTB Manassas)
Coach Madi didn't stumble into volleyball. She grew up inside it. Starting at age 10, she developed a passion for the game that never let go, competing at virtually every level along the way: recreational, travel, and club from 14U through 18U. A four-year all-around player at Centreville High School, including time as a team captain on both JV and Varsity, she played primarily as an outside hitter before transitioning to defensive specialist at the collegiate level and finishing her playing career at the College of Southern Maryland.
As a coach, Madi brings everything she learned as a player directly to the athletes she works with: the grind of fundamentals, the power of teamwork, and the importance of a positive environment. Her coaching style is disciplined, energetic, and player-focused. She believes in setting high standards, keeping practices fast-paced and competitive, and pushing athletes to reach their full potential while never losing sight of the confidence and love for the game that makes it all worth it. She values accountability, communication, and strong team culture, and works hard to create an environment where players feel motivated to push each other, support each other, and keep growing. Her goal is to develop athletes who are more confident, mentally tough, and successful, not just on the volleyball court but as individuals.
Madi served as assistant 17U coach and 18U head coach at Manassas Volleyball Club and is an assistant coach at Centreville High School, where you'll find her bringing the same energy on the sideline that she brought on the court for nearly a decade.
Outside the gym, Madi is an artist, a personal fitness enthusiast, a loyal friend, and the devoted owner of a very full house: two dogs (Gizmo, a husky mix, and Millie, a Cardigan Corgi), two ragdoll cats (Walter and Gibby), and two guinea pigs (Penny and Judy).

kelly jensen
Head Coach, RTB 15 Surge
Coach Kelly’s volleyball career began in Arizona, competing with a top-tier club program and playing for her middle and high school teams. By the time it was over, she had earned a Division I scholarship to Southern Methodist University, started every year as an outside hitter, and recorded over 1,300 kills.
What she did with that foundation is what makes her interesting as a coach. An engineering degree. Years managing large-scale government construction projects. A family. Adult leagues and competitive coed volleyball long after most players have moved on. And eventually, a gym full of young athletes at SYA Volleyball, where she came back to the sport as a volunteer assistant and found that she had something to give that the game had given her first.
Kelly believes volleyball is a platform — not just for athletic development, but for building the habits that follow a player everywhere: communication, adaptability, discipline, the ability to function under pressure as part of something bigger than yourself. She coaches the fundamentals and the person simultaneously, and she does it in an environment where working hard and enjoying yourself are treated as the same thing, not opposing choices.
Outside of volleyball, Kelly used her engineering degree to work as a construction manager overseeing large scale government projects for many years before shifting her focus to her growing family. When she is not cheering on her children at their various sporting events, she enjoys reading, watching movies and spending time with her family, friends and dog.
She joins RTB Volleyball — Chantilly as Head Coach of the 15 Surge, bringing 25-plus years of experience, a competitor's standard, and the kind of perspective that only comes from having lived the game at every level worth living it.

kandipan Sivanandhan
Head Coach, RTB 16 Summit
Discovering the sport in 6th grade while growing up in India, volleyball quickly became more than recreation. It was competition, community, and something worth chasing. He played actively until 2005, when a move to the U.S. for work pulled him away from the court. But the sport doesn't let go that easily — reintroduced in 2016, he's been playing 2–3 times a week ever since. That kind of consistency doesn't happen by accident. It happens when something genuinely matters to you.
On the court, Kandipan is precise, patient, and deeply invested in the individual in front of him. He coaches with a technical eye and a mentor's instinct — understanding that the same cue lands differently for every athlete, and that part of the job is figuring out which version of the truth each player needs to hear. He focuses on building well-rounded athletes: players who are sharper in their technique, stronger in their confidence, and more resilient in their character than when they walked in. Skill without mental toughness is a ceiling. He works on both.
Since 2018, Kandipan has been coaching with Southwestern Youth Association (SYA), working with athletes across middle and high school levels — from house leagues to competitive club teams. He brings that same continuity and care to RTB, where the standard is simple: every player leaves better than they arrived.
RAY LAW
Head Coach, RTB 17 Apex
Ray has been coaching youth volleyball since 2021, working across every level of the development pipeline — recreational leagues with VYI, club programs with SYA, his own skill clinics, and now as assistant JV coach at Lake Braddock Secondary School. He knows what players look like at every stage of development and he knows exactly what it takes to move them from one level to the next.
What sharpens his technical eye is an unexpected source: badminton. Ray competed seriously in the sport for years — and while the two games look nothing alike on the surface, the mechanics transfer in ways most coaches never think about. Footwork, arm swing, reading movement, reacting to chaos in real time. The precision that competitive badminton demands translates directly to the kind of technical coaching Ray brings to the volleyball court. It's not a detour from volleyball — it's one of the reasons his breakdown of form and mechanics is as sharp as it is.
His coaching philosophy starts with a single belief: mistakes are not the enemy of progress — they are the path to it. Ray teaches players to become self-aware, to diagnose their own errors, and to make the adjustment without waiting for someone to tell them what went wrong. His ultimate goal is to develop players who become their own best coaches — athletes who don't need someone standing over them to get better, because they've internalized the process themselves.
On the court Ray runs fast-paced drills and game-speed reps. He values repetition not for repetition's sake but because consistency and confidence are built the same way — by doing the right thing over and over until it stops feeling hard. He understands volleyball for what it actually is: a game of organized chaos where perfect passes, sets, and hits don't exist. What exists is a player's ability to read a non-ideal situation, make a quick decision, and execute under pressure. That's what he trains.
RTB Manassas
glen martin
Founder & Club Director, Manassas Volleyball Club
Head Coach, RTB 18 Storm
manassasvolleyballclub@gmail.com
Some people find volleyball. Glen Martin built a home for it.
Glen's coaching journey began in 2009 at the Manassas Recreation Center, where he first started working with youth athletes and realized that what he was doing was less about the sport and more about the people playing it. In 2013, he took that belief a step further and founded Manassas Volleyball Club to reach a wider community of young athletes and give them a program worthy of their potential. What started as a local club became a decade+-long institution, developing hundreds of Northern Virginia players and sending more than a few of them back to the court as coaches themselves.
On the high school side, Glen has built an equally impressive resume. He has held coaching positions at Manassas Park High School, Osbourn High School, and Colgan High School, and currently serves as Head Varsity Coach at Centreville High School, after serving as JV Head Coach and Varsity Assistant coach for several years. The through-line across every stop is the same: a coach who shows up prepared, demands more than his athletes think they're capable of, and earns their trust by delivering on that expectation.
Glen holds certifications in CAP 1, IMPACT, SafeSport, concussion training, sportsmanship, sports nutrition, and CPR, and has completed the full VHSL coaching curriculum. He brings that same standard of preparation to everything he does — on the court and off it.
GEOFF PUTNAM
Lead Technical Coach
Over 15-plus years of coaching volleyball, Geoff has worked with athletes at every level — middle school through varsity, travel teams, club programs, and co-ed adult leagues. He has run a co-ed open adult league in Fairfax, Virginia for over 17 years, a program that speaks to someone who doesn't just coach the sport but genuinely lives inside it. His high school coaching resume is one of the more decorated you'll find in the region — five NVIAC regional championships, three years of undefeated divisional play, a third-place finish at the NHSVBT National Volleyball Championship in Omaha, and four VHSAA state championships. Those results don't happen without a coach who knows how to build a program, not just a team.
His club experience runs equally deep. Geoff joined MVBC in 2017 as Assistant Coach of the U18 AAU National Tournament team and has coached multiple age groups across multiple seasons since. He has also worked with youth players through Chantilly Volleyball Club and Braddock Road Volleyball Club, giving him a broad view of how players develop at different stages and in different environments.
What sets Geoff apart beyond the résumé is where his attention actually goes — the individual. He works with players one-on-one to improve performance both physically and mentally, and his coaching philosophy centers on one thing: helping every player realize their full potential on the court and, above all, enjoy the game.
Geoff also serves as a certified club and high school referee — a dimension of the game many coaches never engage with at that level, and one that gives him a perspective on the sport few others have. He holds USAV IMPACT certification and joins RTB Volleyball in a player and coach development capacity, bringing the kind of experience that makes everyone around him better.
rachel pascua
Asst. Coach, RTB 18 Storm
Coach Rachel brings a rare combination to the court: competitive playing experience, elite-level coaching, and a parent's perspective. That last piece is where it all started — in 2021, watching their own daughter fall in love with the game and grow into it, Coach Rachel found a deeper calling in youth volleyball. That front-row seat to a young athlete's development shapes everything about how they coach today: a genuine investment in helping every player develop both a love for the game and the technical foundation to back it up.
Coach Rachel spent two seasons (2023–2025) as an Assistant Coach for the 17U/18U divisions, helping older athletes sharpen high-level tactics and prepare for collegiate-level competition. Now leading the 14U program, the focus shifts to building from the ground up — fundamental mastery, court awareness, and team culture.
That foundation traces back to Coach Rachel's own playing days as an Outside Hitter for Clash Volleyball Club. It's a full-circle journey — club player, volleyball parent, head coach — that lets Coach Rachel connect with players and families from every angle.
hannah halbert
Head Coach, RTB 17 Hurricanes
Coach Hannah has been playing volleyball for over 17 years and coaching for 13. They have coached athletes ranging in age from 9 to 18 and have helped several players launch their college volleyball careers. Hannah has played extensively throughout middle school, high school and college, participating in co-ed and women's club & recreational leagues across Northern Virginia since age 11.
During high school and after graduation, Hannah served as an assistant coach at their former middle school, where they played a key role in transforming the team and the program. They helped lead the varsity team to district championships two years in a row before joining MVBC in 2018 as a head coach of the 13s team. In 2022, they also served as assistant coach for both the JV and Varsity teams at Unity Reed High School. Most recently, Hannah was the Freshman Head Coach at Centreville High School and will serve as the JV Head Coach for the 2026–2027 season.
Their coaching philosophy focuses on developing each athlete's individual strengths while fostering confidence, discipline, and a genuine love for the game. They emphasize relentless hustle, a strong work ethic, positive leadership, and being an outstanding teammate both on and off the court. They hold certifications in CPR, IMPACT, SafeSport, Abuse Prevention & Awareness, and Concussion Training.
Coach Hannah is the head coach of our 17s team.
dylan petrin
Head Coach, RTB 15 Inferno
Dylan Petrin runs on two things: volleyball and energy — and he brings both in equal measure every time he steps on the court.
Dylan's volleyball story starts on the sand. Growing up in Virginia Beach, he spent his first five years playing beach volleyball before the sport pulled him in every direction it could — indoor 6s, beach doubles, open-level reverse coed tournaments. Fifteen years in, he's still competing at a high level and still as locked in as the day he started. That kind of sustained passion for the game doesn't go unnoticed by the athletes around him. It's contagious in the best possible way.
Coaching was a natural next step — not because someone told him to, but because Dylan genuinely loves watching people get better. He's spent years providing private coaching, working with younger athletes in after-school and summer programs, and finding ways to pour what he knows into whoever is in front of him. He's a player's coach in the truest sense: high energy, deeply invested in the individual, and at his best when the athlete across from him is breaking through something they couldn't do yesterday.
Dylan joins RTB Manassas as Head Coach of RTB 15 Inferno, and he is exactly the kind of coach this program was built around — someone who shows up with everything he has, every single time.
emily shea
Asst. Coach, RTB 15 Inferno
Emily’s competitive career started in middle school and never really slowed down. By high school, she was a First Team All-District setter at Hickory High, an MVP, a Districts champion, and a repeat contender at Regionals. She spent five years in club volleyball, made two trips to nationals, and traveled to tournaments across the country — the kind of resume that comes from someone who treated the sport seriously from an early age.
She took that seriousness to the University of Mary Washington, where she transitioned to libero and competed at the collegiate level — a position change that speaks to her volleyball IQ and her willingness to do whatever the team needs. Decades later, she still competes, with beach volleyball doubles in Virginia Beach remaining a fixture in her life. Twenty-plus years in and the love for the game hasn't faded a bit.
Coaching was a natural extension of that. Emily has worked with youth beach volleyball athletes, passing along not just technique but the kind of genuine enthusiasm for the sport that you can't manufacture. She brings both to RTB as Assistant Coach of 15 Inferno, where Dylan Petrin's program gains a coach who has played this game at every level worth playing it.
JIMMY DAO
Jimmy Dao grew up in Springfield, Virginia, and volleyball found him early — he started playing in his youth and stayed with it all the way through high school. In 2022, that connection came full circle when he reconnected with the sport in the best possible way — coaching his daughter through her middle school years at Saint Timothy Catholic School in the CYO Volleyball Program.
That experience was the bridge into club coaching. Jimmy joined Manassas Volleyball Club in 2024 as an Assistant Coach for the 15U Thunder team, bringing a coaching philosophy built on three things: learning, encouragement, and fun. He believes those three aren't separate from competition — they're what make players want to push themselves in the first place. Get the environment right, and the growth in skill and team performance follows.
Jimmy is USAV IMPACT and SafeSport Certified, and he's back for another season as Assistant Coach of the 16 Waves at Manassas Volleyball Club, ready to bring his experience — and his energy — to the next group of athletes.
Morgann elmore
With nearly a decade of volleyball experience, Morgann brings both depth and versatility to the court. A varsity starter from her freshman year, she built a reputation as a reliable, high-level athlete with strong leadership on and off the court. Six years of club volleyball — four of them at Manassas — sharpened both her technique and her competitive mindset along the way.
Her experience at both defensive specialist/libero and setter gives her a uniquely well-rounded view of the game. That range shows up in her coaching: she's passionate about instilling defensive discipline, sharp serve-receive fundamentals, and the strategic awareness it takes to run an offense.
Off the court, Morgann's known for an upbeat, personable coaching style that players respond to. When she's not coaching, she's spending time with family, walking a dog, or finding an excuse to go shopping. Her goal as a coach is simple: build a positive, motivating environment where players feel supported, confident, and inspired to grow.
The bar is going to rise. We’re looking for others ready to raise it with us.
RTB Volleyball holds a simple belief dearly: that coaches who are genuinely invested in their athletes, held to a clear standard, and supported at every turn will produce something extraordinary. If you share that belief, keep reading.
RTB is built differently. We have high expectations of our coaches: cultural alignment, genuine investment in every player, and an unwavering commitment to the standards that make this program what it is. In return, we invest in you. Training and development pathways, clear expectations to lean on, a coaching staff that supports each other, opportunities to lead clinics, build your online presence, and create something that extends well beyond a single season.
Coaching here won't be for everyone, but it might just be for you. If you're looking for more than just a team to coach and you want to be part of something that matters, that grows, and that stands for something — we want to hear from you.
