Meet the coach
A decade of athlete-first coaching.
Kevin is a Certified Strength and Conditioning Specialist based in Glastonbury, Connecticut. With 10 years of coaching experience, Kevin has dedicated his career to designing and establishing successful sports performance programming for youth athletes.
Over the past decade, he has worked with athletes ranging from seven-year-old beginners to Olympic-level competitors. His ability to serve a wide range of athletes can be credited to long-term programming models which enhance the longevity of athletes throughout their entire career and utilizes an educational approach to ensure athletes learn how to maximize their potential.
Kevin's area of expertise is preparing high school athletes for the demands of college athletics. While studying Exercise Science at Sacred Heart University, Kevin competed as a Division I track athlete. As his collegiate career progressed, he faced numerous season-ending injuries. These injuries have served as an invaluable lesson, learning firsthand the importance of establishing proper technique, good recovery, and stress management strategies.
These lessons influence every aspect of programming—from proper warmup, exercise selection, and movement mechanics, to recovery strategies. He believes all athletic performance comes from a strong foundation of movement: like building a skyscraper, there is no 50th floor without a strong foundation.
