About Us

Go Otters!

Before we started Marble City Water Polo in 2023, we were looking for an accessible water polo club that wasn’t hours away and we couldn’t find one.

So we made our own.

Marble City Water Polo is bringing water polo to East Tennessee. We offer competitive youth water polo programs from March through October. No experience is necessary to join!

MCWP is a registered 501(c)(3) nonprofit organization.

Marble City Water Polo Coaches

Train With The Best Otters

Your water polo goals may change over time, but the desire to improve is always there. Our coaches are committed to helping you reach and exceed the next level of performance, no matter where you begin.

Kevin Heinrich

Head Coach

Kevin brings nearly three decades of water polo experience to Knoxville. Before starting Marble City Water Polo in 2023, Kevin started Bluff City Water Polo in Memphis, Tennessee, in 2013. That program grew to 100+ families and is still active. Prior to that, he coached the University of Richmond Women’s club team for several years.

Kevin began officiating for the Collegiate Water Polo Association (CWPA) after graduating college. In 2012, he was selected to officiate the National Collegiate Club Championships at Oregon State, and in 2016 he was chosen to officiate the same tournament at Notre Dame. In 2017, he was invited to be a goal judge at the NCAA Women's Championships in Indianapolis. He remains an active official for the CWPA. Additionally, he helped form the Tennessee Water Polo Officials Association (TNWPOA), which is the organization that is responsible for staffing the high school competitions in the state.

Will Greenberger

Assistant Coach

Coach Greenie started his playing career in Memphis as a junior for both Christian Brothers High School and Bluff City Water Polo. During his senior season, he received 2nd Team All-State awards. He went on to play club water polo at UTK where he was a captain for 2 years. Greenie began his coaching career in 2019 for BCWP as an assistant coach where he was able to learn under some of the best coaches in Tennessee. He continued coaching in Knoxville for Bearden High School until COVID restricted play. He currently coaches for both UTK and MCWP and wants to continue to see the sport grow in Tennessee.

Samir Natour

Assistant Coach

Samir is a Knoxville native attending the University of Tennessee to study biomedical engineering. He started his water polo career as a freshman at Bearden High School and played for two years. Over that time, he developed skills and a love for the game. While the pandemic cut his high school career short, he decided to relearn the sport at UT. In his first season back, he received the Most Improved Player award and has been continuing to learn more ever since. Now, he continues to get involved with the sport, serving as a captain for the UT team. Samir is excited for the seasons to come and can't wait to help develop the next generation of the sport.

Renee Sowko

Assistant Coach

Before joining MCWP, Renee hadn't been involved in water polo since playing in high school in California. She got connected with MCWP while looking for opportunities to start a masters water polo team in Knoxville, and was an assistant Otter coach for the 2023 inaugural season. Her goal is to boost interest in the sport and encourage youth participation.

Carsyn Munson

Assistant Coach

Carsyn coached the MC Otters in their debut season, after having played water polo in San Diego, California for four years while in high school. Outside of coaching and getting new tattoos, she focuses her energies on working in a little bistro in Kingston and is currently in school pursuing her EMT licensure.
