"Excellence with a gentle touch"

Dr. Heidi Sun, DDS, FAGD

Dr. Heidi SunDr. Heidi Sun has been practicing with Sun Dental since 2004. She recently took the practice over from her father, Dr. Randolph Sun, who opened Sun Dental in 1975. Sun Dental has been delivering friendly, personal dental care to its patients for almost four decades now.

Like her father, Dr. Heidi Sun is a graduate of Loma Linda University School of Dentistry. While in school, she received a Silver Award for academic excellence along with scholastic and clinical recognition from the Academy of Implantology. She is a Fellow of the Academy of General Dentistry and is a member of the American Dental Association, California Dental Association and Redwood Empire Dental Society.

As an ongoing effort to maintain a cutting edge on dentistry, Dr. Heidi Sun (our "Dr. Heidi") has continued her education and training, and honed her skills by constantly discovering new methodologies and techniques in dentistry. She handles complex dental procedures with ease, and provides a pain-free and comfortable experience for all of her patients. Dr. Heidi Sun offers laser dentistry and Six Month Smiles braces which provides a patient with cosmetically straight, beautifully aligned teeth in just 6 months!

Dr. Heidi loves children and has taken care of many "little ones" at Sun Dental.  She has a tender and caring touch with children, and offers them a comforting environment in our Kids Room. She and her husband Ben live in Lakeport, CA with their two beautiful daughters—Elyse and Grace.

Dr. Heidi enjoys running and power walking and has participated in marathons and triathlons. She also enjoys skiing, snowboarding and camping. She is the group leader at her local church in the children’s Sabbath school program. In her spare moments she reads, cross-stitches, paints, travels, and loves watching movies.
