Patient Reviews

My experience was amazing. All of the staff has been caring and very good at talking me through the whole process. Dr. Lohrbach, I can’t thank you enough for the freedom from pain. I have told lots of people my experience and recommend you. The texts were super helpful, it’s like they read my mind and answered my questions. Thank you for helping me be active again!

Dr Lohrbach spent a reasonable amount of time with my wife and [me]. His Explanation about the technique of anterior hip replacement was extremely helpful. Dr Lohrbach took the time to listen and that was very important to us.


I had hip pain for a year. I wasn’t able to walk up and down stairs without being in pain. Before surgery, I was walking about 3000 steps a day in pain. Now I’m able to walk well over 20,000 steps a day with no pain. Love this Guy.

Waited 5 only minutes. He was familiar with my health history, explained the procedure well, answered all my questions thoroughly, and I was done and out the door. Exactly what I needed.
