  • Kristin Sims, Lead RDH

    Joined the practice: 2015

    I began my journey in the dental field as a dental hygiene coordinator in 2001. At this time, I realized I had a true passion for dentistry. In 2006, I received my registered dental assisting (RDA) license. After becoming an RDA, I decided to expand my knowledge and become a dental hygienist. I completed my training as a dental hygienist at Cerritos College. I’m very proud to be a part of this profession, as I enjoy making my patients feel comfortable and delivering the best possible treatment to them. 

    When I leave work, I go home to my husband, Justin, and my two children, Kinsley and Nixon.  My family and I love all things outdoors; we stay very active. I would love to meet you and provide you with a wonderful caring experience.
