Dr Gelnar has years of experience. He completed my surgery 7/13/2010 at Edmond OU Medical Center. He also performed the same operation on my mother last year. I found out after that the anatomy of my gall bladder is not text book so it took almost double the time of my mothers surgery. But as a patient, I wouldn't have been able to tell if he didn't tell us. He did a great job and I would recommend him to anyone needing this procedure. He knows his stuff. Thanks!!!
