Years ago, Dr. Trava (4 stars) did a root canal for me. He was not available, so his office suggested Dr. Petix. She was GREAT -- gentle, caring, and thorough. She explained the procedure, the equipment, and the results. Daisy (Dr. Petix's assistant) was also a gem. I fully recommend her.
I can't comment on the cost because I didn't compare it with other dentists and fortunately my insurance pays most of it.
