Carol Truong Peppers, Registered Dental Hygenist

I graduated from San Joaquin Valley College in 2000 with my dental hygiene degree and have been a part of Dr. Heitman’s periodontal practice ever since. I perform periodontal maintenance and scaling and root planing treatments and have over 10 years experience using the endoscope.

I enjoy working with patients one on one, helping them improve their oral health and teaching them how to maintain a healthy smile..
I feel very fortunate to have been born and raised in beautiful Sonoma County. Now I get to raise my family here as well. When not working, I enjoy working on my home improvement projects with my husband, gardening, anything crafty and chasing after my sons.
