I've been using Dr. Greenberg for years now and will continue to travel from Henderson to Summerlin to do so. His staff is friendly, personable, and accommodating. Directions are always provided in addition to a paper outlining all directions. I have always felt each concern and question I had was addressed and in fact considered by his staff and Dr. Greenberg. You will be able to recommend this office to your friends and family with confidence. Call them. AND, if you have a question or concern just ask them. I'm pretty sure they will assist you.
