Dr. Curtis Contro was born and raised in the South Bay Area. He attended the University of California, Davis (UCD) where he graduated with a Bachelor of Science degree in Psychology. He went on to attend dental school at the University of California, San Francisco (UCSF). He fell in love with San Francisco and after graduating, Dr. Contro was blessed to pursue his dream career of becoming an orthodontist.

He completed an additional three years of training at the University of California, San Francisco, (UCSF) specializing in Orthodontics and Dentofacial Orthopedics. In addition to obtaining his specialty certification at UCSF, Dr. Contro obtained a Master‘s Degree in Oral and Craniofacial Sciences and conducted cutting-edge, three-dimensional research on the temporomandibular joint.

Dr. Contro is an active member of many dental organizations such as the ADA, CDA, SCCDS, PCSO, and AAO. He strives to provide the highest quality of care by using treatment modalities on the forefront of orthodontics such as Invisalign, self-ligating brackets, and temporary skeletal anchorage devices. He believes in early interceptive orthodontics, an approach that allows for growth modification and prevents the narrowing of treatment options for patients when they are older.

Dr. Contro is a firm believer in patient education and makes it one of his top priorities throughout the duration of treatment to teach and explain what he is doing. Much of orthodontics relies on the patient’s cooperation to get to the ideal finish. A patient that understands the “why” is more likely to do the “what.” He spent many years before becoming an orthodontist tutoring and mentoring children and considers it a privilege to continue to do this through orthodontics.Dr. Contro is married to his college sweetheart, Steph. They have one son, Jax. In his free time, Dr. Contro enjoys photography, reading, golf, and of course goofing around with his son.
