Dental Staff


  • Callie , RDA

    I've been working as a periodontal assistant since the year 2000, and with Dr. Mao since 2005.  I still enjoy coming to work everyday, working side by side with my amazing team members, and getting to know and help each patient.  My flexible job position as a chairside assistant most days, and front office assistant on Fridays, allows me to get to know both sides of the office, and helps me appreciate both equally.  Outside of the office, I enjoy volunteering, the outdoors, reading,  and spending time with my husband and two beautiful daughters. 

  • Lisa , Scheduling Coordinator

    I have worked in the dental field for over 30 years, specifically in the area of Periodontics. For the past 21 years, I have had the pleasure of working at Periodontics Northwest. I was a clinical assistant until 2007 when I made a change to scheduling coordinator. I enjoy working with our patients and strive to make them feel comfortable and welcome at each appointment. With the support of Dr. Mao and our amazing staff, I feel we provide that for our patients. I enjoy traveling, hiking, interior design, gardening and entertaining with family and friends.

  • Laura , Registered Dental Hygienist

    I began my work in the dental field as a dental assistant, and then later went on to pursue my career in Hygiene. I fell in love with the perio-involved patients during my clinical. Following graduation from Shoreline Community College, I had the opportunity to immediately start working in a Periodontal office. When my former Periodontist retired, I was introduced to, and hired by Dr Mao, here at Periodontics Northwest.

    I enjoy educating and working with our patients. It is my desire to make their dental experience enjoyable and to help them feel at ease. I feel fortunate to work with such a supportive staff, who strive to always put patient care at the forefront.

    When I am not at the office, I enjoy spending time with my family and friends. I am the mother of three incredible young men. I love sewing and painting, the outdoors, bicycling, hiking with my dogs, road trips and traveling back road on my Harley.

  • Isabella , RDA

    I graduated from West Coast Dental Assisting School, in Bothell in 2016 and began working with Dr Mao January 2017.  I enjoy getting to know people from all backgrounds, and this has helped me to better understand patient needs.  It's been a pleasure working with such a great team and kind Doctor--it is helping me continue to grow as an Assistant!  

    When I'm not in the office, I'm often enjoying the outdoors, making art or volunteering.  I also enjoy being in the company of my friends and family. 

  • Bilha , Financial Coordinator

    I have enjoyed working in the dental field for 25 years. I become on board with Periodontics NW in Feb., 2020. The short time that I have been here I have enjoy working with Dr. Mao and these amazing ladies. I enjoy spending my time off relaxing with my handsome young man and beautiful baby girl.
