My UCSF dentist referred me to Dr. Quinn & Dr. Gwa to correct a bite issue. I had both Invisalign (Dr.Quinn) & braces (Dr. Gwa) and am very pleased with their assessment & continued progress to correct my bite. In addition, the support staff have been efficient & empathetic during my fittings & adjustments. Their office is in the nationally registered 1929 building by Timothy Pleuger and has spectacular 17th floor view of downtown SF.

We've been seeing Dr Quinn since our kids were in elementary school on the recommendation of our dentist. He is a seasoned pro, and it extends to every aspect of the office. The staff is kind, professional and welcoming. Three of us have been patients, and they have consistently guided us through the invisalign process, making adjustments and accommodations as necessary. It took each of us about 10 months to get to amazing teeth. We highly recommend Dr Quinn.

I had an urgent visit to install aligner cables and had only half an hour to get back to a plumber appt. The attending doctor was super fast, professional, and accommodated me on an extremely short time frame. Love the office and everyone working here, A+ expertise and attention to detail.

Dr Quinn and his staff are all amazing!! They are always professional, clearly know what they are doing, and treat everyone with respect. They make the environment fun too. I just got my braces off today. The treatment was done perfectly and it totally resolved the issues I was having! Previous places I had gone to were not able to resolve the issues. I feel so fortunate I was referred to Dr. Quinn! I highly recommend them!

Our experience at Dr. Quinn’s office has been nothing short of amazing! My son, who started his orthodontic treatment at 10 years old just finished, and we couldn’t be happier. The staff made the entire process so easy and stress-free, especially for my son. He was compliant throughout, and I truly believe that’s because of how comfortable and confident they made him feel. From start to finish, the team was friendly, knowledgeable, and professional. I highly recommend Dr. Quinn to anyone in need of orthodontic care. Thank you for such a positive experience!
