Dr.Hejazi is very professional and skilled. The only critique I'd give is while he was drilling my tooth, remnants from inside my mouth were spraying all over my face, nearing my eyes. I requested for a pair of goggles if it wasn't too much of a bother, and they were compliant. His assistant is kind and helpful, but a bit rough on my gums.
However, the receptionist is an overweight caucasion woman who is extremely rude everytime I encounter her during the billing process. If it wasn't for the professionalism of everyone else, I'd seek more welcoming staff. She is the "bad apple" of their office and I'd recommend a more personable employee, but that's just me.
