Smile faster than you think!

Customized orthodontic

treatments as unique as you


I started Days to Smile as a boutique orthodontic clinic in downtown San Francisco to help busy people achieve amazing smiles, on their time. 


We use the latest technology combined with clinical excellence to create a custom plan for each of our patients. 


I consult with each patient personally and craft innovative, individual plans to work with their schedule.

By carefully selecting the best orthodontic technologies, I've been able to accelerate individual treatments for the best results in a fraction of the time.
