I had a right hip replacement. Dr. Ritzow also did my left hip eight years ago. Had a great experience with Dr Ritzow, Kim and his staff. I am pain free. Always willing to answer questions. The texts that I received daily were helpful and encouraging. Their phone calls checking up on me were also nice.
