Colby Smith, DDS, MAGD



Ask any of his patients and they will tell you that Dr. Smith is patient, sincere, and dedicated to helping you achieve your best possible smile. Imagine a doctor who takes time to explain your options, answer all of your questions, and has your wellbeing as his top priority.

Dr. Smith grew up only a few miles from the office, graduating with honors from Bella Vista High School, where he was a three-sport athlete and varsity team captain. He went on to UC Santa Barbara, where he was an Honor student, earning a degree in Biochemistry and Molecular Biology in only three years. Most importantly he met his wife Stacie at UCSB, where they both worked as scientific scuba divers. They were married in 2011 and have two amazing daughters that make life a never-ending outdoor adventure, art project, or both. 

Dr. Smith is fortunate to have been practicing dentistry since 2008. He earned his doctorate and completed advanced residency training at UCLA, where he also taught students and residents for over ten years. He has received many professional accolades and is board-certified in General Dentistry, an achievement equalled by fewer than 1% of all dentists nationwide. Dr. Smith continues to stay at the top of his game. He completes over 150 hours of continuing education every year, teaches courses for other dentists, and has published several scientific articles. He continues to learn so he can provide you with the best, most comfortable dental care possible.
