I had a root canal treatment with Dr Matosian done almost 20 years ago and never had any issues. He was also very friendly and made my overall experience great. I had another root canal performed by another dentist over 2 years ago and now I started to fill a lot of pain, I'm seriously consider to go back with Matosian to see if he can fix whatever was done wrong. Even though their prices are high, for serious treatment is worth the price, specially when you get good quality and piece of mind
