About Dr. Robert S. Quinn, DMD, MSD - Union Square
Dr. Rob Quinn draws adults with complex bite and crowding cases that other orthodontists turned down, often resolving them with Invisalign instead of extractions or jaw surgery.
Reviews frequently describe Dr. Quinn taking on difficult adult cases—patients switching from failed teen orthodontic work or seeking alternatives to extraction and jaw surgery—and finding lower-intervention paths using Invisalign and self-ligating braces. Many notes mention 3D scans and computer simulations used to lay out treatment plans, along with costs and timelines, before starting. The Union Square office is described as modern with skyline views, and appointments are said to run on time with minimal waiting.

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.

Dr Quinn and team gave me a straighter teeth. I wish I had seen his team years ago. His team is caring and thorough. If my daughters need orthodontia, I will take them here. Much appreciation for Anne at reception. She remembers all the patients!

10+ years ago, I experienced a devastating fall that in part required pre/post surgery ortho care during my adult years. Dr. Quinn and his staff are top level with knowledge, experience, expertise, and professionalism. The team examines all details to determine the best and high-quality plan of action. They are kind, empathetic, relatable, and funny! They welcome you like the family you want to spend Thanksgiving with. Now, years later, I recently returned to check in on something and was greeted with hugs and smiles, as though I never left. I would highly recommend this team for all your ortho needs, where you are not just another client.

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.
