After 15 years of my family going to Dr Greer, we are very, very disappointed him. He ripped us off on the price of the cleanings, insisting on charging us $159 for a "periodontal cleaning" that was no different than a regular cleaning. Overall the cleanings are lame, I know because I have my teeth cleaned by a real periodontist hygenist who is infinitely more thorough. Furthermore, we have changed dentists to Dr Skiba in Walnut Creek, his regularly priced are much more thorough than Dr. Greer's hygenist. I asked Dr. Greeer to call me about the excessive charges several times, and he refused. Very sleazy after my family of 3 being a patient of his office for 15 years. So glad we ended up changing to Dr. Skiba as the quality and thoroughness of the work is much more thorough. Dr. Greer is an arrogant dentist who overcharges for services that he doesn't deliver. He has terrible customer and patient support. All he cares about is getting his money. Do not go to him.
