Bryon Reidenbaugh - Club Founder

   Swim Conditioning Coach, 10U Mixed, 12U Girls & 14U Girls Teams

Born in Whittier CA, Byron discovered his love of swimming at the age of 8, excelling on various teams throughout Southern California.  Swimming with relentless focus and determination, Byron was named All-American in swimming two years in high school, and two additional years at Fullerton College.  He went on to qualify for the Olympic Trials in swimming, and received a full scholarship to swim and play water polo at Colorado State University.  There, Byron reached Division One NCAA Championships two years.  He placed in the top 20 in both the 100M backstroke and 200M individual medley for two consecutive years, and was ranked in the top 25 in world in the 100M backstroke.  

In 2002, Byron established Capistrano Valley Aquatics (now Alliance Aquatics Water Polo Club), building a career from his success and passion of swimming.  A self-proclaimed swimming geek, Byron works out daily, and continues to swim competitively in open ocean races.  His passion, success and unique swimming background give him singular insight while working with his students, allowing him to instruct students with insight and precision.  Although he specializes in all four competitive strokes as well as streamlining and flip turns, he works with all levels of swimmers, including beginners.  His method of combining instruction with enjoyment offers a unique approach to coaching, one which has afforded success to his coaching staff and students alike.  Byron inspires his students daily to reach their full potential, while his humorous nature and ready smile endear him to all.  Equally important, Byron makes time throughout the year to support charitable causes such as the Susan Komen Foundation, and Swim for Life.  Byron's expertise in the water, easygoing nature and charitable contributions have made him an icon in the community, and a shining example of conduct and virtuosity. 


Coach Christopher Smithson - 14U Girls & High School Girls 

A California native, Christopher grew up in the San Fernando Valley where he was an avid athlete, who spent his summers swimming, surfing and diving. He attended a small, college-prep boarding school, and lettered in the two sports offered: basketball and baseball. College, as far as his parents were concerned, was for academics, so his collegiate athletic experience was limited to intramural sports.

Years later, he settled in Orange County and started raising his family. He was determined to keep his children safe in the water, and began enrolling them in the requisite swim classes: beginning  with "daddy and me" for son, Cruz, at six months old, swim lessons for several years and progressing to swim team. The first aquatic club his son participated in offered swim and water polo, where Christopher discovered "basketball in the water" and fell in love with the game. He became an immediate student of the game.

Initially, his seven-year-old son, was taught under the theory of "the bumblebee school of sports" - just follow the ball... Chris would pull his son aside and provide additional direction to separate him from the pack. The Head Coach saw this and asked him to provide the same direction for the rest of the team. The rest, as the saying goes, is history - his coaching career was born! 

He began attending clinics, voraciously researching books and videos on the game - he devoured any all information he could regarding the sport. Coach Chris could not feed his thirst for more information. Though there is nothing like hands on experience, he accepted coaching positions to gain experience.

Coach Chris has coached many players over the years. (His son, Cruz, has now graduated from the Air Force Academy, playing water polo all four years there, and daughter, Cassidy, is talented junior on the San Clemente High School varsity team.) He has coached for large and small clubs, but prefers to coach for clubs who place a priority on developing talent while emphasizing a firm foundation of the sport.

With smaller clubs, he has made five trips to the medal rounds for national championships, and has WON THREE NATIONAL CHAMPIONSHIPS. Two years ago, Alliance added the 16U and 18U age groups for girls. Our newly formed 16U Girls team has medaled in the lower divisions of the Junior Olympics each year they have made the trip to JOs with Coach Chris.


Coach Tim Renden - Head Alliance WPC Boys' Development

Coach Tim answers to his calling every day on the pool deck, when he shows up to teach water polo and life lessons.  Tim's passion for the sport and his love of teaching children make him a natural for his role as coach of the 12U division of Alliance.  The kids' positive response and enthusiasm for his class are testimony of his skills as coach, mentor and role model.  

Growing up in Lake Forest, Tim fell in love with swimming in the South Coast Swim Conference's Lake Forest II Dolphins'.  He joined TRAP club water polo team, and continued playing his 7th and 8th grade years in preparation for high school.  He attended Santa Margarita Catholic High School, lettering in Boys Varsity Water Polo and Swimming, and was named “Most Inspirational” three years in a row (2002-2004).

In addition to his accolades as a top athlete and motivator, Tim places high value on education and morality.  Holding a Bachelor's degree from Concordia University, and his Teaching Credential from CalStateTEACH (CSULA) in Primary Education, Coach Tim is also teaching in the Irvine Unified School District.  Coaching and teaching children will always be his passion, and he chooses to coach water polo because of the great complexities of the sport (one sport with similarities to many) and the discipline, honor, respect and sportsmanship; he instills those character traits in his players both through instruction, and through examples in his daily life.  In his free time, Tim loves to read, swim, surf, golf, camp, and trade.  He counts himself lucky for the instruction and leadership in the association of all current and former players & coaches who had and continue to inspire him to be humble each day. Coach Tim has over 15 years of high school and club coaching experience that have resulted in numerous team championships, medals, records, and other accolades. Each and every year he continuously looks forward to sharing his knowledge with the Alliance players in his charge.


Coach Madi Matsushima - 12U Girls

As a former high school and college athlete, Coach Madi brings many years of water polo and swim experience to her position as our 12U Girls coach. 

In addition to coaching water polo at Alliance, Madi is a swim coach for the Nadadores. Madi also coaches high school water polo at Dana Hills HS and Capo Valley HS.

Coach Madi understands what it takes to be a successful athlete. More importantly, she knows how to coach athletes to reach their potential - and have fun doing it!


Coach Arash Borujerdpur - Coaching Assistant, All Levels

Coach Arash knows a thing or two about being a student athlete, and he also knows how to lead people and bring them together. We are pleased that he is here to share his passion for water polo with our players.

Arash has been involved in competitive sports, including soccer, basketball and swimming, since childhood. While on the swim team at Saddleback College, he was recruited to play water polo. After two successful seasons of competitive water polo at Saddleback, he transferred to Cal Poly Pomona to complete his Bachelor’s degree in Engineering. Cal Poly Pomona is a great school to study engineering, but they don’t have a water polo program, so Coach Arash channeled his love of athletics into intermurals. He accepted a leadership position on the Civil Engineering Department’s sports teams. He worked with the teams to make them more competitive, and led some of them to intermural sports championships!

After earning his Engineering degree, he joined the coaching staff at Alliance Aquatics, where his younger brother and sister practice. Though he works full-time as a civil engineer, he carves out time to coach youth players, because he is passionate about teaching the game to the athletes at Alliance, and helping them develop as players and people.

Arash has an insatiable appetite for all things water polo and currently plays on a Masters-level water polo team. He continues to play for the love of the sport, and in his never-ending pursuit to improve his skills.

Setting up Alliance athletes for a lifetime of success, in and out of the pool, is his primary goal as a coach. He expects his athletes to be open to learning, to respect the sport and each other, and have fun playing!
