Dr Wassef is awesome in diagnosing the issue. My daughter has a wart it was not going away and painful Nitrogen treatment was very a horrifying experience for her (she is 5 yr old), then a friend recommended me to Dr Wassef and he started treating her with some topical meds and the wart is getting better. He is very polite and very confident and very reassuring that all in going well and that she will get rid of this. We are very satisfied and happy with his services, his staff is excellent.
