She strives to provide quality care while shaping positive experiences for each and every patient, no matter their age. Every smile transformation is unique, and Dr. Sandra hopes that every patient enjoys their journey!

Dr. Yen has been moving up and down the California coast for much of her life. She grew up in southern California, and she moved up to the Bay Area to attend Stanford University, where she graduated with a Bachelor’s of Science in Biology with honors. She then headed back to SoCal and received her Doctor of Dental Surgery degree from UCLA. Dr. Sandra graduated in the top of her class and was inducted into the Omicron Kappa Upsilon national dental honor society. Following dental school, she completed her Orthodontics residency at Montefiore Medical Center in New York City, the university hospital for Albert Einstein College of Medicine.

Together with her husband and young daughter, Dr. Sandra has fallen in love with everything Sonoma County has to offer and they have decided to settle down locally. In her free time, Dr. Sandra loves running, working out, hiking, trying new restaurants, playing with her beloved chihuahua rescue, and of course enjoying every moment she can with her child.

Dr. Yen is very excited to serve the orthodontic needs of Rohnert Park and the surrounding communities!
