Great swimmers and great teams are built by great coaches. Zeus has a long-standing reputation for having coaches who take the time to get to know each swimmer and provide them with the individualized instruction and motivation they need to progress. Zeus swimmers start out as early as age 5 and swim until they graduate from high school – many go on to swim in college.

Our coaches focus on setting goals with each swimmer and work with them to realize their goals and achieve their full potential. Our coaches are committed to each swimmer’s success and creating a positive team environment. They are actively engaged in the growth and development of our swimmers at every age and skill level and become important role models and mentors in their lives beyond the pool.


  • Dennis Flores

    Head Coach

    It is hard to believe this is already my second decade as a Zeus coach. It is amazing to watch and guide the budding Future Star swimmers into dedicated athletes that meet their swimming goals each season… then send them off to college.

    Dennis is in his 12th year with Zeus, now in the role of Head Coach. He has proven himself season after season as an exemplary coach, mentor and leader. For the past 11 years, he has served as the Head Age Group Coach and was nominated for both Connecticut Senior and Age Group Coach of the Year for 2016. In 2008, he was awarded Age Group Coach of the Year after his 10 and under squad won the Connecticut State Championships. He was also named the 2016 FCIAC Coach of the Year as the Darien High School boy’s Head Coach. Prior to joining Zeus, Dennis coached for the YMCA Middies Swim Team in White Plains, NY where he was also Assistant Aquatic Director. 

    In his nearly 20 years of coaching, Dennis has built a strong reputation for motivating and inspiring young swimmers to achieve success at all levels. He focuses on both the physical and mental development of swimmers, emphasizing the importance of teamwork, determination, patience, self-discipline and self-confidence. He believes these qualities are important for his swimmers to learn and utilize both in and out of the pool. His love for swimming and his dedication to the sport and developing young athletes is evident every time he walks onto the pool deck. He also holds a degree in Business and Marketing from the Westchester Business Institute.
