To whom it may concern: if there could be an Olympics for Endodontics(root canal dental surgery) Dr. Mark O. Manoukian, D.M.D. and his surgical /office staff would be the GOLD medal winners hands down. Dr. Manoukian is very professional — PAINLESS, miraculously fast, and he quietly talks you through the entire procedure. If a root canal is in your future, he should be your first and only choice!
