I had a root canal done here nearly 2 years ago. First of all, he did 2 when I only needed 1 because he couldn't figure out which tooth was hurting me so bad, then one of the root canals he filled 4 mm shorter than he should have. This tooth has been infected for 2 years. When I filed a complaint with a group he's a member of, he called and offered to fix it (I had begged for months for this) he did a surgery but never redid the root canal so now I am having to pay to have this surgery done AGAIN by another endodontist. Dr. Griffen is a really nice guy and from what the dentists say, used to be good, but really needs to retire.
