"Dr. Mattar is a wonderful surgeon. I'm so blessed and happy that he was the one doing my surgery. I experienced no pain (used the On-Que pain ball and it was a miracle too), no nausea and recovered very quickly. Dr. Mattar is extremely knowledgeable in these surgeries and I recommend him highly. If I every have to have gall bladder or anything else done, I'm going to see if he can do it!"
