I was referred to Dr. Tennant for treatment on my hip. While no one wants to hear that you need total hip replacement, Dr. Tennant was from the start professional, explaining the procedure, post surgery and what to expect moving forward. At no time did I feel afraid or apprehensive about my decision to have total hip replacement and I am constantly amazed at the new outlook on life I have as I do not even think about my hip and the pain I suffered for over a year. Thank you Dr. Tennant & Gretchen(his assistant)for your caring nature and helping me get back to living life pain free!
