    I was referred to Dr. Hardcastle after bad experiences with 2 other doctors. The referral was from physical therapists to my wife, who was their patient. Dr. Hardcastle asks questions, tries to make you feel better about getting injections and delivers injections well. I have visited him at least 3 times and feel very comfortable with him. I absolutely recommend him.

    Obviously he has a reputation for success and optimum treatment, as I experienced. He is very busy but willing to take time to answer questions, if you are quick enough to ask before he moves on! He did a great job on the total knee replacement surgery I had.
