Meet The Team

Gloria Ho-Donesky


Gloria Ho-Donesky completed her Bachelor of Arts from San Francisco State University prior to her earning both her Associate of Science in Dental Assisting and her Bachelor of Science in Dental Hygiene from Loma Linda University. She has served as president of the San Francisco Dental Hygiene Society for two years from 1992-1994.

Her primary focus is on the prevention of gum disease. Her philosophy is to inspire her patients in being co-partners in their own dental health.

As a clinician, she finds the greatest satisfaction is in connecting with her patients and educating them on total wellness.

Outside of dentistry, she believes learning is fun and challenging.  She has been studying voice and sings in different organizations in the bay area.  She has also been studying French, enjoys the opera and loves to travel. 

Norma Del Toro


Norma has been practicing dental hygiene since 2014. She makes it her goal to create a relaxing and comfortable atmosphere while you are in the dental chair. She maintains open communication if you have any concerns during the appointment. As her patient, you can expect a gentle yet thorough cleaning. Together, you can both work as a team to reach your optimal oral health. 
Norma grew up and lived in Novato until she was 12 years old. She married in 2014 and moved back to Novato. In her spare time, she enjoys spending time with her daughter and husband. She also enjoys hiking, bicycling, and spending time with other family members and friends.

Bonnie Sun


Bonnie Sun, RDH, joined our practice in 2019. She graduated with a bachelor of science in dental hygiene at Loma Linda University. She worked for several years in San Francisco before taking a long break from the profession. She had decided to reactivate her license by taking several continuing education courses. It didn’t take long for her to be back in the dental hygiene seat. Her skills as a dental hygienist are reflected by her detail oriented personality and gentle caring hands. 
Bonnie was born in Maui but grew up in San Francisco and has lived primarily in Marin county. As an avid equestrian, her passion is riding and jumping. She recently joined a dragon boat racing group in the Bay Area.
