Relentless Performance has been an excellent program for my daughter. As an athlete always trying to push herself further, the team at Relentless has done an amazing job to propel her through strength training and conditioning. Mason keeps classes upbeat while providing a high level results driven program. Highly recommend!

I worked with Pete for 4 months post hip surgery. As a professional hockey player I was looking for someone that could relate to and could help me get back as quick as possible. Pete did everything he could to get me back quickly and safely as possible. He’s a tremendous human being with a lot of knowledge and I’m grateful I was able to work with him and his staff. Hands down the best treatment and rehab in the area. I’m back playing hockey again just 5 months after surgery all thanks to Pete and his hard work!

Two of my sons, both competitive athletes, have excelled in each of their sports by working with the team at Relentless.
They learned to build muscle and gain endurance the correct way.
I am impressed with the results I see from the training and guidance they are receiving. I highly recommend Relentless for all training and fitness goals.

Relentless Performance has been a game-changer for my son. After suffering a fractured spine, he needed both physical therapy and the right kind of strength and conditioning to get back to playing hockey (as a goalie) and lacrosse safely and effectively.

What makes this place truly special is their understanding of athletes and the demands of different sports. Dr. Pete Inserillo, a doctor of physical therapy, is exceptional. He customized a program tailored specifically to my son's recovery and performance goals, ensuring he could build the right strength and conditioning for both hockey and lacrosse.

Dr. Inserillo is incredibly responsive and truly cares about his patients’ progress. I found Relentless Performance through a Facebook Group, and the glowing reviews were absolutely spot on. They have an exceptional team.

If you’re looking for experts who know how to work with athletes and deliver results, I highly recommend Relentless Performance.

I can't express enough how incredible Relentless Performance has been for my daughter. To start, she had ACL reconstruction in May 2024, and the surgeon told us it would take 9-12 months for her to return to dance, depending on how aggressive her rehab was. We initially chose another sports physical therapy clinic, which was decent, but by October (5 months post-surgery), she hadn't made the progress needed to meet her 9-12 month target for returning to dance and acro.

We reached out to the surgeon for recommendations, and he highly recommended Relentless Performance. After speaking with Pete, it was evident that he understood the importance of her goal to return to dance and had a realistic approach to managing expectations. He created a comprehensive plan that started with physical therapy to quickly build strength and mobility, followed by a seamless transition to their coaching program. After two months of physical therapy, she moved into their coaching model, which is a truly exceptional and personalized program tailored to each individual's needs.

By January (7 months post-surgery), she was back dancing full-time. In February, she competed in her first dance competition and absolutely crushed it. Not only is she stronger than ever (full-body strength), but she’s also been frequently complimented on her remarkable strength by both peers and dance coaches.

My ex-husband, who was initially skeptical, is now singing Relentless Performance’s praises. The entire staff is knowledgeable, supportive, and welcoming. I’m so grateful we found them!

Where do I begin!? Miracle worker, should I say? Pete from Relentless Performance truly brought me new hope for my shoulder injury. 10 weeks of rehab on my shoulder brought me the ultimate relief I could only dream of, after suffering with chronic pain.

There was physical therapy, strength training and muscle work incorporated. In addition, there was motivation, inspiration and coaching to help with the emotional aspect of my injury. Pete was kind, professional, and efficient in his abilities.

Pete and all the staff at Relentless Performance were warm and welcoming. I always look forward to walking in those doors as they not only improve and rebuild you but they make you feel like family while doing it.

If you’re skeptical like I was, don’t keep waiting and check out Relentless Performance. You’ll wish you started sooner! I look forward to my next phase of nutrition and continued maintenance with Pete on this fitness and well being journey. Thank you Pete and staff for rehabbing my shoulder and making me feel confident in my performance. You are the best of the best and I’m so grateful.

I’ve been working with Dr. Pete at Relentless for about 8 months. I had been dealing with a number of injuries, some chronic and some more recent. The progress I’ve made over this time has been remarkable.

I’m 66, very active, and I had been a competitive Olympic Weightlifter, having qualified for the National Masters competition in 2022. I had to withdraw due to multiple injuries, and had to modify my training. I finally realized that it was time for a change.

Initially, Pete focused on establishing goals and diagnosing root causes for the various pain and restricted mobility. We started with targeted PT and custom workouts. As we progressed, I realized that the plan was not only to get me back to lifting, but was geared to improving my balance, mobility, flexibility, as well as strength. As a result, I am now pain free, and in the best condition I’ve been in since my 20’s. I am on track to gradually work my way back to competition; hopefully qualifying again for the Masters Nationals.

Thanks to Peter and the entire staff at Relentless for helping me achieve my goals.

I can’t say enough about how great a place Relentless is and how excellent Pete is as a physical therapist and strength coach. Pete’s approach to physical therapy is different from and far superior to any other physical therapy I have experienced as a competitive runner and coach for over 40 years. In addition to his technical expertise and knowledge, Pete does an excellent job of making me (and I’d say all of his clients) feel comfortable, confident, challenged and encouraged. Strength training with Pete and LeighAnn is fantastic and always tailored to where I’m at, whether I’m in perfect training condition, coming back from a break, or working my way back as part of rehab after an injury. They seem to know just the right way to go from whatever starting point I’m at to whatever level of greater strength, capability, confidence and overall health I want to attain.
I couldn’t recommend Pete and Relentless more highly….just outstanding!
