Lisa contreras

Hello! My name is Lisa and I am from Brentwood, CA. I recently graduated from Saint Mary’s College in Moraga, CA, where I received my Bachelor’s in Health Science. I have always had a passion for health care but did not know which route to take until recently when I decided to take a dental assisting class. Since then, my focus has been completely on teeth! I hope to someday complete a dental hygiene course or maybe even apply to some dental schools. I feel so lucky to have found Sustainable Smiles and Dr. Young, who is such a supportive and caring employer, as well as a really fun person to work with. When I’m not thinking about teeth, I like to be with my friends and family, hanging out with my two dogs, and reading or watching something. I love the Harry Potter books and my favorite show is Parks & Recreation. I also love to travel, and so far I have been to Cambodia and Spain, but I hope to see more of the world soon! We welcome you to our office and look forward to meet you!
