Stephen Hood

Personal Trainer

A University at Buffalo graduate and former Navy Diving Medical Technician, I now specialize in finding exercise solutions for people who are trying to shed some weight and/or improve their overall health and wellbeing. As a Corpsman and Navy Diver, I was fortunate to work and train alongside many amazing people in some of the top US military Special Operation’s units. The values I learned there, I now carry to my clients through my commitment to understanding their needs and goals and my sense of duty towards helping them to achieve those goals in a safe manner. I approach every interaction with honesty, integrity, and my client’s best interests at heart.

I am passionate about educating my clients throughout every step of the process with clear, concise, and easy-to-understand explanations and demonstrations, so they can make the most out of every training session. While I am knowledgeable and hardworking, at the end of the day when it is all said and done, I genuinely care about you the client, and your well-being.
