Dr. Chun did research and consulted with other professionals and experts to come up with a plan that saved her canines. I like her decisiveness, and her thorough explanation of the plan and what to expect. She is a true professional and an expert in her field. My daughter is now in her braces and we are already seeing results from Dr. Chun’s work. My son had his braces removed today and he has a beautiful smile. I highly recommend Dr. Chun’s office and everyone on her team!”

It turned out the result is more than what I expected. My teeth looks and feels perfect!!! Thank you Dr. Chun and Staff for your help, patience (time flexibility) and advise. It’s been 2 & 1/2 years of journey but it’s really worth it. Thank you so much!!!”

Marites Smith, Adult, 10/2014

“It’s been a great experience working together with Dr. Chun and her staff. At first having braces takes a lot of work with all the limits and boundaries of what you can eat. It takes time to adjust or get use to having braces for a couple of weeks until it starts to get comfortable. By working together with the staff, having braces is no problem. If the patient does their part and the staff does their work, then the patient’s teeth will have a perfect smile. By following the instructions given by your orthodontist, your results will come out great. I recommend joining this orthodontics team and you’ll have a marvelous result.”

Alex Loi, Teenager, 6/2014

“My experience here at this office was friendly. I was satisfied with the way they treated me as a patient.

I would highly recommend Dr. Chun.”

Linda Martinez, Ryan Martinez’s mom, Teenager, 8/2012

“I have been a patient at this office for a little over a decade now. During my time here, I can honestly say I truly appreciate the hospitable service and professionalism of the staff. Even though the idea of having orthodontic work done may be unappealing, I highly recommend the office of Dr. Chun and the more than competent staff.”

Ian Wu, Adult, 5/2012

“I started my braces in January 2009. I was referred by my dentist. I’ve heard good things about Dr. Chun’s office from my trusted dentist of many years. All I can say is, I made the best decision. The staff of Dr. Dianne Chun has been very thorough, detailed, and fabulous to work with. They are the most friendliest, warmest, and passionate people. They help me get through my fear and discomfort which was only at the beginning. I’d like to say I will continue to recommend them to all my family & friends. You guys rock!

Past Patient, Teenager, 3/2012

“What a great experience this has been. I’ve always had bottom teeth that looked like a picket fence in need  of repair. When my daughter came in to have her teeth straightened, I asked Dr. Chun if there was any hope for me. After a consultation I decided to finally get things straightened out. I was in my late 50’s when I started and now I’m 62. It took about 24 months and what a great improvement. If you have ever thought about what a difference a great smile can make, it’s never too late! By the way, the staff at Dr. Chun’s office is the best! Things don’t happen overnight but the team at Dr. Chun’s works with you every step of the way. Thanks Dr. Chun!”

SC, 3/2012

“The last two years that I have been here have been eventful. When I first came my teeth weren’t all that great, but then Dr. Chun and the staff had come together to give me the confidence I needed by fixing my teeth. They gave me braces and retainers that helped align my teeth together. The staff always made sure I was okay if my teeth hurt. They are caring, kind, and awesome. Because of them I can’t stop smiling, showing my great and improved pearly whites. It’s a great feeling to be told by others that I have perfect teeth. It’s all thanks to Dr. Chun and the staff.”

Natasha Kiri, Teenager, 3/2012

“Dr. Dianne Chun’s office is a very comfortable office. I love her staff – they are all so sweet and always make sure you’re completely comfortable in their office.

Corrina Anselmo, Teenager, 3/2012

“My daughter came to Dr. Chun’s office two years ago with crooked, protruding teeth. When she ate vegetables, she would have food stuck in her teeth. Her lips couldn’t close properly, and her profile looked strange. She just got her braces off and her face has been transformed, and her teeth look like dentures, so perfect. Dr. Chun and the staff are meticulous and professional. Friendly family atmosphere.”

Past patient, 4/2012

“Thank you for the efforts that Dr. Chun and her staff put into my teeth for the past 2 years. Without their efforts, I wouldn’t be able to smile as comfortable as now. They gave me a great smile and confidence. This procedure is a life-changing experience. Thanks again, Dr. Chun!”

Wilson Lau, Teenager, 5/2011
