Client Reviews

“Dennis is extremely knowledgeable and it really shows in the treatment plans he provides. He is creative and adapts to the needs of the individual. What I love most about working with Dennis is that he really pays attention to you and that at every step of the process you can tell he really cares so much about your recovery!”

“As an ultra distance enthusiast, my legs take quite a beating and it's important for me to take care of all the small things before they become bigger problems. Dennis has been so patient with me bombarding him with questions about any nagging issues. I like that he really takes the time to explain what the root cause of the issue is and gives me exercises to strengthen these weakness and stretches to alleviate the issues. He's makes it very easy to understand. Also as a massage client, Dennis is really accommodating and makes you feel very comfortable.”

“I’ve  gotten the chance to work with a number physical therapists over the past decade, but Dennis far and away stands above the rest. Instead of just reacting to the current aches & pains I was dealing with during my marathon training block, Dennis took the time to understand the bigger picture of how I run/walk/move/live. With this lens, he created a tailored program for me that would not only alleviate the pain I was going through, but also attack specific muscles that I needed to strengthen as a runner. His sessions are high-intensity, but are also logically sequenced in a truly accesible way. Working with Dennis not only mended my aches & prevented them from becoming bigger injuries, but he also fully invested himself in my development as a runner. I achieved PR’s in 2023 in the mile, 5k, half marathon, and full marathon, and I 1000% would not have done so without him. If you’re in New York, and want to become a stronger, healthier athlete, go see Dennis Serna. The man is the best.”

"Dennis Serna is a first-class trainer who focuses on the body mechanics as a whole. He is a good observer and notices any impediment to a well-functioning body. He is tough and gentle at the same time. His sessions are full of work and go quickly. His experience with physical therapy makes him well equipped to make good decisions about what movement is best suited to his clients. I went to Dennis in pain and always came away feeling better. I highly recommend Dennis as a trainer!"

— Ruth Torres

“Dennis is an experienced and talented athlete himself, who will characteristically go above and beyond to help others achieve their goals. He’s been a lifeline for me many times over - diagnosing/treating an ITB issue (5 weeks pre-marathon), regularly recommending strength building exercises, delivering pre-race tune ups to my very tight calves. He has even paced me through a few workouts himself over the years! I’ve never met a soul on earth who does not love Dennis Serna. He’s a pillar of the NYC running community and you’d be hard-pressed to find a better human being, PT and coach.”

“I trained with Dennis for the Chicago Marathon in 2023. He was great at fitting workouts around my schedule and addressing any specific needs I had. We worked on the right exercises that would help me be a better runner without aggravating my old injuries. He aligned the workouts with my overall marathon training, helping me avoid injuries during the block. Thanks to his expertise, I started the race in great shape. Highly recommend him for anyone looking to get to the starting line healthy and achieve their goals.”
