Front desk people are awesome! Scheduling is done so well! Everyone is friendly! I have less pain and feel so much better and stronger! I have learned so much! Thank you! I am looking forward to being back for maintenance!Diane D.
I was referred to PDR by my doctor’s office during my pregnancy. At the time I initially began to be treated by the staff at PDR I was nearing my 27th week and suffering from SI pain. The staff at PDR is extremely knowledgeable and has been helpful in my recovery. Thank you.Kyesha L. Pregnancy Aches
ALL of the employees were outstanding! Truly, from the front desk to the PT's & OT's. I felt I was learning new things constantly and especially the little every day tips on how to function and adjust to daily activities to become less painful.Kari S.
For almost 30 years, I was misdiagnosed by doctors. I was told to prepare for my life as a disabled person. I couldn’t give up, so I went in search of answers on my own. It was a blessing when I found PDR. The doctors and staff found what was wrong in one visit. Two years later I am living a normal life. This has been a second chance I never thought I would have. Today I am 95% pain free and loving life again. I can never thank all of you enough.Mary R. Pain Treatment
I came to PDR after learning I had, at 43, major degeneration in 3 areas of my back, 2 bulging discs, 1 torn and arthritis…at MY age? I thought…I don’t want to do surgery, wasn’t an option, cortisone was, but I didn’t want to go there either, so I turned to PDR, where I learned new techniques and core strengthening exercises that helped improve my pain and help me live my life to it’s fullest! Thank you everyone!!Kelly Back Pain Treatment
Seriously everyone is amazing. They are all unique in their approach/ interactions. I will miss you all.Ben E.
They ALL are so good, that I really would have a hard time pointing out just one. Each one has their own personality with total respect for me and making me feel as if I were their only patient. They’re all strong with me, which I needed, but all in a very good way. Love all of you and thank you all for helping me!Carol
