I've seen about half a dozen dermatologists in Vegas. One was good but they no longer took my insurance. The last few were dismissive and casual about checking my skin for pre-cancerous spots etc., so I never went back. When I came for my first appointment I could tell that Dr. Greenberg was serious about what he does. He is thorough and attentive to detail which I appreciate and didn't act like I was neurotic because I wanted a checkup. As a result of this fantastic service, my teenage son is now a patient too. The treatment he received was also excellent and the facialist was very nice and his skin looked great right away.
