I have been going to Dr Sun for all my dental needs for over 15 years he is the best in the high desert! He did my braces and anyone who has had braces knows it can be an uncomfortable process but having a great orthodontist like Dr Sun makes all the difference. I recommend him to everyone I know. His staff is friendly and they always take time to explain everything out to you so you know exactly what the plan is for your dental needs.

Dr. Sun and his staff provide excellent dental care! They are good listeners and take my questions seriously. I thought another tooth was cracking requiring a crown. Dr. Sun and Nicole took their time to look into my concern. It was just a small healing area in the roof of my mouth. Crises averted. I truly appreciate Dr. Sun and his staff!

Been going to Dr. Sun for over 20+ years. Dr. Sun and staff are the best in business. Dr. Sun, hygienist and front staff know what they are doing and run a well oiled machine at the practice.

Dr. Sun and his staff are wonderful! They accommodate me and my son by giving us back-to-back teeth cleaning and check up appointments since we live out of town. Dr. Sun and his hygienist (Nicole) are helping me with a little problem with my bite. I was scared I had a bad tooth. Dr. Sun clearly explained how we will diagnose and treat my problem. He's so clever and cares! Dr.

Sun has kept his offices (2 locations) open during our COVID conditions. Other dentists have closed their offices. I learned that Dr. Sun has picked up a number of those patients to help with their dental needs. I appreciate Dr. Sun keeping his doors open! I'm sure those patients appreciate him as well. Thanks!

Best dentist and hygienist I've ever had hands down. They made us feel comfortable and at ease throughout the entire visit. The ladies in the front office are so friendly and helpful with scheduling appointments as well. My entire family goes there now and we couldn't be happier with the service provided :-.

Dr Sun is always upbeat and he and his front office staff, dental assistants and hygienists, are all extremely pleasant people and outstanding at their respective jobs. We have been with Dr Sun for over 12 years and have never had an unpleasant experience. He is always available for dental emergencies and takes very good care of his patients. We highly recommend Dr Sun for all your dental needs.

By far the best dentist I have ever been to. Dr. Sun is amazing. He went above and beyond my expectations on fixing my teeth. I will never go anywhere else.

After working with Dr. Sun for quite a few years, I had seen first-hand the care and professionalism he has with his patients. So much so, that I still make the 3 hr drive a couple times a year to have him take care of my family(even though I work for a dentist out of state). His staff are friendly and are very knowledgeable. Highly recommended!

Every member of my little family loves Dr. Sun. We travel all the way from Chino Hills just to see him. He provides gentle care and he is most knowledgeable. There is no other dentist for us.

My family and I have had all of our dental and orthodontic work performed by Dr Sun and his staff for over a decade. Now my adult children continue to go to him with their spouses and families. He cares about his patients and goes out of his way to make everyone comfortable. He is flexible when an urgent matter needs attention. He is also flexible with payments etc. His prices are very reasonable. I highly recommend Dr Sun and his staff.
