Meet our Hygienist


Katie Lawson, RDH


Katie Lawson graduated with honors from Concorde’s Dental Hygiene program in Garden Grove, California. Katie excelled in her studies and participated in a study conducted by UCI`s dental research team. Katie also received her certification in dental laser cleanings enabling her to provide highly advanced treatment option available.


Katie grew up in Huntington Beach, California, where she graduated from Edison High School. She lives in Huntington Beach with her husband and son. On her free time, Katie enjoys cooking, exercising, playing with her dog, and trying new restaurants.


In June 2015, Katie joined our dental team as our new hygienist, replacing Chi Nguyen who after working and devoting nine wonderful years decided to stay home and to be a full time mother.  Chi has been instrumental in helping Katie to become familiar with our patients’ needs.  Katie’s focus is to continue to educate and provide current information so that her patients can improve their oral health, thus contributing to the well-being of their general health.  To ensure that her patients receive the highest level of care, she continually attends many educational courses to stay informed on the most current advances in the field of dentistry.

Katie enjoys working with Dr. Barzegar because they share the same philosophy on the importance of preventative care through education and routine dental visits. Since each patient has his/her own individual and unique need concerning the state of his/her oral health, personalized treatment programs are developed to ensure that quality and effective care is provided.


When patients seek results that cannot be achieved through routine cleanings alone, Katie works with Dr. Barzegar to develop special treatment plans.  For instance, missing teeth can be replaced with dental implants and whitening of teeth can be done through laser treatment.  These options along with other cosmetic procedures are among the services that can be provided at Dr. Barzegar’s dental office.
