HIs facilities are extremely clean and He has videos playing for the kids. I would say He has average customer service. As far as cost, He is less expensive than another pediatric dentist we were seeing. Also, when another dentist insisted on pulling two teeth from my daughter, Dr. Park said to have patience. That patience paid off and we did not need the teeth pulled. My kids both really like him. I think he is very fair on what procedures need to be done and what don't need to be done.
