Dr. griffin did my root canals so poorly that they actually had to be redone within one year. My OBGYN actually made me go to another endodontist to have him fix it which cost me $10,000 (to redo the root canals and do the surgery where they drill through the bone to release infection. Griffin left me with a huge abscesd in my gum from infection and refused to correct it even though I was pregnant and this is very serious when pregnant. He needs to retire. I filed an ada complaint as well, and I wish I had sued him.
