Dr. Wolff and Dr. Sperber (Skip) share the same office and Skip recommended Dr. Wolff (who bought Skips practice) after going through several other dentist, but they did not measure up to Skip's excellence and professionalism, and Dr. Wolff did. I had Dr. Wolff perform bridge and crowns installation on me and they came our great! I do believe that Dr. Wolff is a excellent dentist and a great person!
