"Working with Bill over the past few years has been the experience of a lifetime. I was able to get shredded for my wedding, as well as hitting all of my competitive athletic goals - including #1 ranked 4.5 tennis tournament player in the country, in 2025."
“Working with Bill is nothing short of amazing. He listened to my goals, tweaked my programs when I wanted more upper or lower body, and always checked in with me to ensure I was drinking my water and getting after a good workout. He’s knowledgeable, supportive, motivating, and overall the best trainer I have ever worked with.” -Michelle O
"I worked with Bill last spring, and the experience was fantastic. He created a personalized workout plan that was realistic, challenging, and tailored to my goals. I saw great results in a relatively short amount of time, which really motivated me to stay consistent. The app he used made a huge difference—it kept me accountable and made it easy to track my workouts and progress. Bill is knowledgeable, supportive, and genuinely invested in helping his clients succeed. I highly recommend him to anyone looking for a personal trainer who delivers real results."
