Testimonials
“Nicholas DeMarco is outstanding! In my case his combination of expertise in Physical Therapy and his own athletic knowledge enabled him to design a truly individualized program adapted for my age and prior bad back! Few personal trainers could offer that. And he is the nicest guy!”
—Deborah Davenport, MD
“After being diagnosed with osteoporosis, I knew I needed to make a serious change for my health. Starting strength training with Nick 14 months ago has been one of the best decisions I’ve ever made. Not only have I seen a significant improvement in my T-scores, confirmed by a recent bone density scan, but I also feel stronger and more capable in my everyday life. The increase in my muscle tone and strength has been an added bonus. What sets Nick apart is his depth of knowledge and genuine care. He brings expertise in nutrition and overall health, and he generously shares that knowledge in a way that is both practical and encouraging. Nick has truly made a difference in my life!”
—Susan C., 67
“I started working with Nick back in October 2025, not fully committed at first. My goal was to build and maintain muscle, stay strong, and keep my mobility as I got older. After a couple of months, I realized what a great coach Nick is and decided to fully commit to losing 35 pounds. He listens, understands your goals, and supports you every step of the way. He also keeps workouts fresh by changing up the exercises, which makes it easier to stay engaged and consistent. I’m already seeing changes in my physique, and as someone who never enjoyed going to the gym, that says a lot. I’ve been showing up to every scheduled session, and that level of accountability has made a huge difference. If you’re looking for someone who is knowledgeable, motivating, and truly invested in your progress, I highly recommend Nick.”
—Patti Ronneberger, 54
“Nick DeMarco is a game changer! I first met him after my husband’s stroke. Nick is a gentle motivator whose Physical Therapy background and desire to enable others to regain their abilities shines through. The progress my husband made with Nick was nothing short of a miracle. Nick gave him the confidence that his mind and body needed to recover. After that, I decided I wanted to train with Nick. He developed a personal plan to strengthen my core and the areas in need for an older individual. I feel better than ever and working out is now a weekly part of my life. Thank you Nick for the kick start I needed!”
—Sherree O., 69
“As a long-distance runner, I realized I needed to incorporate strength training into my routine. Nick was instrumental in breaking down workouts by muscle group and helping me target and strengthen underutilized areas. He demonstrated a strong knowledge of anatomy and clearly explained the rationale behind each exercise. He also played a key role in supporting my husband’s recovery from knee replacement surgery. As a fellow healthcare provider, I especially appreciate his depth of knowledge, his ability to communicate concepts clearly, and his genuine eagerness to help others. Nick is knowledgeable, compassionate, and a true pleasure to work with.”
