Your history comes first.
We start with your training experience, current ability, and relevant movement limitations.
NASM Certified Personal Trainer • Corrective Exercise Specialist • CPR/AED Certified

I'm Matt Kashetta, founder of Greenwich Performance and a Mobility Specialist. I played lacrosse and began in boutique and group fitness in 2020. I became certified in 2021. I also graduated Summa Cum Laude with a degree in Business Administration, Management. My work brings together strength training, assisted stretching, and corrective exercise.
Since 2022, I've coached independently in clients' homes. I've worked with a wide range of people, including athletes headed to top college programs, and trained dozens of fitness professionals in my methods. Today, I coach private clients and lead a team of mobility practitioners.
The people I work with bring different goals and different starting points. I take the time to understand those differences and build our work around what matters to them. I personally coach every Greenwich Performance session.
Our work is built around consistency: purposeful strength training, corrective exercise, and mobility that support the activities you want to keep doing for years to come.
We start with your training experience, current ability, and relevant movement limitations.
I explain why each exercise belongs in your program and what we are working toward.
Sessions are challenging at a level you can manage, with attention to posture, movement control, and steady progression. We adjust the effort to your readiness that day.
