Patient Testimonials

Matt Miller, MD

“I had knee replacement in June on my left knee. Driving in 10 days, no drugs, pain level 1-2 at best. Just had right knee done (September) two weeks out driving and pretty much back to normal. Dr. Miller is the best of the best. Would highly recommend him and have. The knee done in June, the scar is almost invisible after only three months. He does not rush you and answers all questions. Highly recommend. I am 67-years-old.” – C.G.

“I recently had a total hip replacement after enduring more than two years of horrendous arthritic pain. Dr. Miller and each person on his staff, with whom I interacted, are 5-star in my book. Dr. Miller and his staff to a person are kind, caring, completely professional and immediately attentive to my every need. I was so terribly apprehensive, having never had any surgery, or even been on any medication in my 69 years. I was afraid of not waking up, and if I did, that the pain would be unbearable.”

“Dr. Miller has perfect anesthesia options, makes minimal incisions, and sees to your pain management before you even make up. Before surgery my pain level was 7-8. Waking up, I had 0 pain. In the four weeks since, my pain level has remained at 0-1. I only found Dr. Miller by accident – how very grateful I am!” – C.B.

“Dr. Miller is an amazing person. I need a total hip replacement and was fearful of the pain and put it off. It turned out, Dr. Miller is an expert in pain. I can honestly say that I had very little pain. On a scale of 1-10, during my hospital stay, the highest I reached was 3. Dr. Miller always put me at ease and his staff worked well to make sure I had my prescriptions before my surgery.”

“I made sure to follow all the hip literature and booklets. I attended a hip class prior, which I highly recommend, and thus my visits with Dr. Miller went smoothly, as my questions were not redundant. While in the hospital, Dr. Miller checked on me every day. After being released, I took the medications as prescribed, which eased my recovery. After surgery, I completed six weeks of physical therapy, as per his request. I even kept a journal, making my progress. I just passed my three-month anniversary since my hip replacement, now, I am walking, lap swimming, dancing, shopping, picking up and caring for my grand baby and back to working a full day, pain free!” – Y.J.

"Dr. Miller is wonderful. What more do I want. No pain!! Hip hip hooray! I love him." – L.M.

"God bless you for giving me a new hip! I pray every day for you and your good work. Many, many thanks." – Sister M.

"Thank you for your care, patience, kindness and professionalism. It was all good and my leg is straight. I am doing great!" – A.D.

"We want to thank you for making it possible for our mother to walk and live life with new optimism.
