Kimberley Marble, Surgical Assistant

I grew up in a small town in the Sacramento Valley. We only had one dentist for the small community. My first memories were of how caring this doctor and the staff were to me, which directed me to the field of dentistry. I have had the pleasure of working with the most respected Periodontist in the Marin Sonoma area and finally found a home with Dr. Heitman. I feel fortunate to work with such a wonderful group of women.
