Peter Fields, MD, DC is the best. Twice he was able to fix my torn meniscus (left and right-2 separate injuries) that allowed me to heal and avoid surgery. Dr. Fields is the best in Prolotherapy and PRP injections. With his procedures my body was able to repair my tears both times. For knee or other joint injuries, see Dr. Fields first. It is likely he will also be your last stop as well as you get healthy WITHOUT surgery. PRP is the real deal. It worked for me twice.

Highly recommend Dr. Fields and his staff! They are amazing! A year ago I had a stem cell procedure done along with PRP treatments on my left ankle and I am almost near back to 100%. Thank you guys :

Five stars are not enough for Dr. Fields. I have been an athlete for forty years and sooner or later was bound to have an age-related injury. I had heard of Dr. Fields for many years so when my chiropractor, Dr. Vessey, in Arcadia said we had reached a point where I needed more - the soreness in my tailbone and the numbness that occasionally occurred in my leg could not be healed with manipulation alone. Dr. Vessey told me to see Dr. Fields because he had received Regenerative Orthopedics with exceptional results (he was a college football player, and everyone knows what happens to their backs later in life). Dr. Vessey said that he was going to have to quit working because of his back pain and thought his life was over.) Dr. Fields saved him, so I thought why not me. Dr. Fields looked at my x-ray and MRI and nd after examining me, said that I was a good candidate for his treatment, so I scheduled my first Regenerative Orthopedic treatment (PRP/Prolotherapy).

I was in and out of his office in an hour and a half. I followed his instructions on how to care for my back and by my second treatment, there was a noticeable difference. The third treatment was a few weeks ago. My lower back (the culprit of my problems) may need one or two more treatments, but I am back to my former life swimming, doing yoga, cycling, etc. Am I glad I avoided surgery? You bet! Dr. Fields saved me from surgery and gave me my life back. And thanks to your wonderful staff too.

I was extremely happy with my results. I had a rotator cuff tear and all my other doctors wanted to do was for me to eat a bunch of anti-inflammatories and a surgery in the future.

I've seen Dr. Fields for wrist and knee pain. I wouldn't see anyone else. Even if you're been told you need surgery, see Dr. Fields first!

Amazing Doctor, he was able to help my wife run her first marathon, after she had back surgery she still had a lot of pain, with his help she felt so much better. We only wished we would of found him sooner to avoid surgery.

Prolotherapy was a great alternative to knee surgery for my post-marathon knee injury. Dr. Fields works hard to help patients stay active without invasive and painful procedures. I would recommend prolotherapy and Dr. Fields to anyone who wants to be gentle to their body and stay active a long time. Dr. Fields is a great example of his method. He is doing triathlons every year, at an age when others are winding down.
