"​UNBELIEVABLE dentist. All of my family, extended family and friends go to see Dr. Wong. We have been going to Dr. Wong since he started his practice. I personally have gone to his office for nearly 60 years. His father was also a fantastic dentist. If anyone is afraid to go to the dentist, this is the dentist for you. He is sooooooooooooooooooogentle and tells you EVERYTHING he is going to do. He takes time with you. You NEVER feel rushed. Just cannot say enough about Dr. William Wong!!
