"I had my right hip replaced by Dr. Willis on November 7, 2019 and once again, I had a very good experience. My recovery has been going well and working with Dr. Willis is always a pleasure. Dr. Willis is an excellent surgeon and is always very good with explaining what's going to happen in "not a doctor" terms. That is really appreciated! This is my 4th experience with Physical Therapy at the Langhorne Office. Stephanie Morgan is always professional and great to work with. She gives you a workout program and keeps very close track of how you are progressing and doing the exercises. I appreciate her knowledge and ability to keep me working hard, even though getting stronger after surgery isn't necessarily fun! My experiences have been excellent with Mercer Bucks Orthopedics!"

"Just wanted to say how pleased I have been through this difficult time (hip revision). Dr. Willis is a Brilliant Doctor that is thorough, kind, considerate. He explained everything (good & bad) regarding my hip revision surgery and what to expect. His assistant (Elsa) was there all the time. If I had a question she would relay to Dr Willis and got back with me asap. I also want to thank Jenna and Jennifer for going the extra mile for my physical therapy. I THANK YOU ALL VERY MUCH!"

"Dr Willis is a gifted surgeon. I had Left Hip Replacement and no pain and an amazingly easy recovery. He answered all my (sometimes quirky) questions and in a gentle and caring manner. He was always able to explain everything to me in a way that neither grossed me out or was more than I could handle. I feel that I have been given excellent care during this whole process. He's just great and I'm so glad that he joined the practice when I needed my hips replaced!"
