    Dr. Hasenauer was awesome.

  • Mar 23, 2023

    Dr Hasenauer is fabulous. He takes the time to listen and thoroughly explain. He is realistic and works with me to set realistic expectations. He has a wonderful bedside manner and great sense of humor. I am healing well and am pleased with his skills as an orthopedic especially since my hips were extremely deteriorated and he saw me 2 years after the pain began. He is a master. So pleased he was my doctor.
