Aaron Dean Head Coach & CEO

Coach Aaron comes from a diverse background of over 14 years of competitive swimming experience working under 8 different coaches in Alaska, Washington & Arizona and over 26 years of coaching experience including 18 years of head coaching experience in Washington, Missouri and now in Virginia. 

Coach Aaron’s coaching background started as a volunteer assistant with his age group swim team in Alaska, continued through college and after spending a summer with the University of Michigan Swim Camps under coaching legend, John Urbanchek, in 1995 coaching swimming was solidified as his passion and career choice.  In 1996, Coach Aaron got his first head coaching job as the lead of the newly formed Bellingham Bay Swim Team in Bellingham, Washington.  In 2002, Coach Aaron moved east to Kansas City, Missouri where he led the Kansas City Dolphins swim team (also affiliated with the Little Rock Arkansas Dolphins) for six years. 

Coach Aaron joined the Occoquan Swimming family in 2008 as the general manager and now leads the program as the Chief Executive Officer, Head Coach and National Training Group Coach.  Coach Aaron’s success in coaching includes swimmers that have reached the top of USA Swimming with Olympic Trial Qualifiers, Junior National Champions, All-Americans in USA Swimming and High School Swimming, State Champions, and swimmers across the country competing at the college level.  As CEO the OCCS program has grown from just over 200 swimmers in 2008 to now with over 600 competitive swimmers training in six pools including the home of Occoquan Swimming at Central Park Aquatic Center. 

Aaron’s philosophy in coaching is centered around the inevitable pain and promise that there is no substitute for hard work.  If you want to be better, you must work harder, and the better you get the harder the work becomes in you want to continue to improve.  Swimming is not for everyone, it is a tough sport for tough athletes. Coach Aaron also believes that everyone is unique and thus techniques, motivation, communication and ultimately success comes in different ways.  Using a focus on the commitment to excellence, Coach Aaron uses the keys to building success in swimming (hard work, focus, dedication, discipline, determination) to help mentor kids through the challenges as a student athlete and ultimately in pursuit in the same way whatever career, family or life his students pursue. 

College Swimming Scholarship swimmers that Coach Aaron has coached have or are currently swimming for: Auburn, Virginia, Minnesota, Michigan State, Texas A&M, Truman State, Wyoming, VMI, RPI, Missouri, Missouri State, Washington, Northern Arizona, Boston College, Emory, Air Force Academy, Coast Guard Academy, Manhattan College, Evansville, York, Bowling Green, Towson, East Carolina, Old Dominion, George Mason & Brigham Young, plus swimmers that swam with Harvard, Stanford, Whitman & many other non-scholarship schools.   

After a decorated age group swimming career that started at age 8 in Petersburg, Alaska, Aaron was a high school state champion in Alaska (sophomore year) and after moving to Washington State his senior year of high school won the state championships there as well in the 100 breast.  Aaron attended Northern Arizona University where he pursued a degree in exercise science with an emphasis on physiology while continuing his swimming career as a school record holder, team captain and NAU’s first NCAA National Qualifier over his four years in Flagstaff. 

Aaron’s education is centered around his passion for physiology while also staying up to date with the most recent findings in the sport sciences in biomechanics, kinesiology and psychology.  Aaron has completed the ASCA trainings and qualifications for a Level 4 coach in the sport.  He has 100’s of hours of training at conferences and clinics over the past three decades.  While in the Pacific Northwest, Coach Aaron was the camps director for the association, lead zone coach as well as a member of the technical planning committee and board of directors.  He was named Age Group Coach of the Year in the Pacific Northwest in 2001. 

Aaron and his patient and loving wife, Hannah have been married 18 years.  They live in Centreville with their three-year-old son, Dashel and, a newborn (2018) daughter, Daivey that consume Coach Aaron’s life when he’s not at the pool coaching and/or managing the team.

Kelly Call PW East

This is Kelly’s 20th year coaching (6 with OCCS) and has coached for several teams throughout the US. You will see her involved with almost all of the OCCS events and works “behind the scenes” at CPAC during the day. 

Kelly has coached almost all ages and levels in competitive swimming which gives her unique versatility to lead a variety of practices. She currently is coaching IMR Plus and IMX in PWE (Prince William East). She enjoys these groups because they are very committed and are always willing to push a little harder. Her philosophy each day is to teach the group something new, push them a little further and always have fun in the process. Coach Kelly believes that every swimmer should have a goal and they should always strive to be the best version of themselves. 

“Yes, I teach kids how to be better swimmers. But that’s just the sprinkles. I coach to help kids fall in love with hard work and the feeling of accomplishment. Each one of the kids I work with will hopefully walk away stronger, more confident and have learned skills that will be carried with them throughout their life.” -Coach Kelly 

Lauren Kranz Manassas Central
Joan Craft WARF

Having grown up in a swimming family, swimming has always been a large part of Coach Joan's life. Most of her USS club years were spent with the Naval Academy Juniors Swim Team in Annapolis, Maryland, where she was coached by her mother. While there, she achieved numerous team records (many of which still stand) and state records. She competed at Junior Nationals (multiple top 5 finishes), Senior Nationals, and the U.S. Open. She went on to swim at the University of Southern California where she was a part of their 1997 NCAA Division 1 National Championship team. She brings her experience as a swimmer, as well as her love for and knowledge of the sport to OCCS. She believes strongly that not only is it important to improve stroke technique and times in the pool, but it is equally important to develop a strong work ethic, good sportsmanship, patience, and determination. All while having lots of fun along the way!!

Christine Haslem Prince William East
Coach Christine joined the OCCS family this season and currently coaches PWE IMX & Pre-Seniors. Previously she coached the last 4 years with PWSC (Advanced Pre-Seniors, Advanced Juniors, Summer & High School Prep). Coach Christine was the Assistant Head Coach 2017-2020. Additionally, she was the head coach of both Veterans Park Summer Swim Team (2018) and Stonewall Jackson HS Cross Country/Distance Track Teams (2009-2014). In 2020 she was appointed an assistant coach at the Olympic Training Center's National Diversity Select Camp.

Her swimming career began supposedly before she could walk. That's her mom's story and she's sticking to it. Mom taught lessons in the backyard pool in Florida and Christine snuck out every chance she got to "assist" her. While she was playing to the point of annoyance at USF during her brother's swim practices, the coach said how about we throw her into the pool too. Christine swam year-round from 9-20. In high school, she was state finalist all 4 years 100 fly/500 free/ 200 free and both relays (400 free/medley) while qualifying for several National Select Camps in high school. Additionally, she was an All-American in butterfly and freestyle. Later, competing for University of Alabama, Christine qualified for Olympic Trials and finished 3rd at the 2000 US Open in the 400 Medley Relay. Due to injuries, she had to stop swimming at the conclusion her sophomore year. Training with teammates/Olympians Brooke Bennett, Maritza Corriea and Janelle Atkinson, as well as being coached by USA Olympic coaches Greg Troy and Peter Banks helps her draw upon experience in her coaching.
Those injuries and lack of technical advice have shaped my philosophy as a coach. I am a stickler for punctuality, a huge fan of quality technical tips over massive amounts of yardage, and including sets that swimmers never thought they could complete. Her favorite aspect of coaching is to convince athletes to do things they did not think were possible. Lastly, she's a huge proponent of dryland and improving flexibility to incorporate better technique and prevent injuries.
