Meet Coach Zark
Jon Nazarko is a former 2 sport Division I athlete who prides himself on being passionate, hardworking, and diligent towards his craft in pursuit of helping his athletes reach their goals. The Connecticut native got his start at the University of Rhode Island where he worked with baseball, basketball, volleyball, football, golf, swim & dive, track & field, tennis and soccer athletes. For the last 5 years, he has been in professional baseball with the Boston Red Sox and the 2023 World Series Champion Texas Rangers where he worked with 12 current MLB players and numerous Top 100 Prospects.
Throughout the years the world of sport has continued to evolve forcing coaches to learn and push the limits of their knowledge to best serve the athletes. As a performance coach, Jon has continued to adapt and learn from the best in the game. Jon has taken his expertise in biomechanics and applied them to the athlete’s program both in the weight room, on the field and, more specifically, working with pitchers in the bullpen and hitters in the cages or on-field. This constant pursuit of knowledge and athletic excellence propelled Jon within the professional ranks.
Jon holds a Master’s of Science Degree in Kinesiology from the University of Rhode Island, he is a Certified Strength and Conditioning Specialist (CSCS), a Registered Strength and Conditioning Coach (RSCC), as well as Titleist Performance Institute Certified (TPI). He has 9 years of professional experience from College to Pro, and is the Founder of Zark Athletic Performance.

“...Outside of the weight room Jon is someone I now consider to be a close friend and having coaches and staff you can trust is one of the most important qualities I think you can find. I trusted Jon every day because I know that he wanted to push me to be the best version of myself...”
“... he’s become a lifelong friend. If you want someone who is going to push you everyday to be better and wants nothing but the absolute best for you then Jon is the guy. ”
“... Anybody can put together a workout program, but connecting with the athlete and creating a plan around their specific needs is what Coach Zark is fantastic at... ”
