SRC has been invaluable in my injury rehabilitation process. I've worked with countless PTs, Chiropractors, and other specialists over the last 17 years I've been competing as an athlete. Ron and Brad stand out as the best! Ron has kept me healthy the last two years and played a big part in my recent success competing in Spartan Races. I appreciate SRC's commitment to learning new techniques and listening to their patients.

The Physical Therapy care I receive is the best I’ve ever had. Ron is knowledgeable and always working hard to make sure he identifies the exact issues I have going on. His skills are excellent and help me feel healthy so I can continue to be active. He recommends and demonstrates exercises so I can do them properly with him and on my own. He is very effective at explaining what we’re doing, using language that is easy to understand. I highly recommend Sports Rehab Consulting to anyone needing PT.

Ron Harder at SRC changed my life. I endured 25 years of severe back pain and debilitating spasms. I had seen more physical therapists, chiropractors, and acupuncturists than I could count, along with a few surgeons. I came to Ron out of desperation. Ron does what others do, only way better! He is a brilliant diagnostician, and he takes time to get it right. Within a month, my back was beginning to relax and strengthen; within 6 months I was fully mobile; and a year to the day that I first saw him I was snapping flip turns during swimming workouts without any pain at all. I now think of my adult life in two phases--Before Ron (BR) and After Ron (AR). I still am shocked at the top of a 14er or in the middle of high intensity workouts that I can do everything I want to without any concern at all—and no meds!

I have been going to Ron for several years and while we have had success addressing my "hotspots", more importantly he has taken the long view and addressed my underlying issues caused by too many hours behind a desk, lack of core strength and the impatience of a weekend warrior. I feel like I have made progress every year and can definitely see the results on the golf course. I have confidence in him and can recommend him highly.

As a professional runner I have seen a lot of different PT's. Ron is the most skilled PT I have ever worked with. He analyzes the body and works like a mastermind to solve the problem and not the symptom. I always leave his office feeling relieved and I am 100% confident that with his help I can stay injury free.

I will never forget the first time I worked with Ron. I left the office with less pain than I had felt in years and a huge sense of relief… physical and mental. I was so thankful I had found him. Ron’s approach, techniques and dry needling skills are like no other therapist I have encountered. Everything he does is incredibly calculated and well thought out. It is by far the most individual care I have received in all my years of going to PT. He gives you his full undivided, hands-on attention for the hour and is in tune with the overall big picture - not just the ailment you might be feeling. He also explains why things might be happening the way they are and shows you exercises to help correct them. It’s been so much fun working and laughing with him and improving with each visit. I have been working with him for a couple of years and have since referred friends, family and clients. He is a true gift and a master of his craft!

Ron (and all of the PTs) at SRC offer a level of care that's unmatched in Denver! When you show up for your FULL HOUR of dedicated one-on-one treatment with your SRC therapist, be prepared to receive the full array of the most modern treatment methods, education on your injury, and an accelerated path to recovery. My wife (ACL/MCL) and I (hip/other) have seen SRC post-surgically and for various other injuries. The kind and humble folks at SRC keep our family charging forward, and we always leave treatment with a smile!

I first met Ron in 2016 prior to a hip reconstruction. He has helped me prepare for and recover from bilateral hip reconstructions and a foot fracture. He is incredibly thoughtful and figures out what your body needs to move forward and get stronger. He is our go to recommendation for anyone having any kind of musculoskeletal problem, including my daughter (13 years) and my dad (70+)!
