Seems like a great doctor just wish he wasn't so rushed with all his new patients would like to have spent a little longer

We hit it off well from the get go. Had good conversation mixed with business instead of all business which is great. He spends some personal time with you even though he's backed up and extremely busy. Great personality. This was my first visit since Dr. Salah retired and I didn't know who or what to expect. I'm very happy Dr. Daniel will be treating me. It truly was a pleasure 😊
