Meet The Team


Office Manager & Financial Coordinator

I have worked in the dental field since 1989. Through extensive experience as the office manager, I’ve had great opportunities to expand my knowledge in dentistry and better serve our patients. I have enjoyed working for Dr. Koo since 1997 and the best part of my job has always been getting to know the families in our practice. It’s wonderful to watch the youngsters grow up to be adults themselves and bring in their own families for their dental care.    


I am married with 3 amazing grown children and 5 grandchildren. I love hiking, watching movies, following the Giants and soaking up the sun at the beach.


Insurance Coordinator & Dental Assistant

After completing the Dental Assisting Program at San Jose City College, I joined Dr. Koo’s Team in 2004 as the Insurance Coordinator. I enjoy helping patients better understand their dental benefits and the challenge of keeping up with the ever-changing guidelines of insurance companies.  I am dedicated to assisting our patients with any questions they may have regarding their dental insurance, billing statements or scheduling.  On some days you may even see me in the back office assisting Dr. Koo. I enjoy working with our wonderful staff and it feels great to be part of a team that strives to help patients achieve their best dental health.

In my spare time I enjoy crafts, photography, shopping, cheering on the 49ers and most of all spending time with my beautiful family. 



Registered Dental Assistant

I graduated from San Jose City College in 1994 and became a Registered Dental Assistant the following year. I started working for Dr. Koo early in 2014 and have enjoyed meeting all of our patients and working with the staff. I am so happy to be a member of this dental family.

In my spare time, I enjoy hiking local trails, exercising at the gym, watching movies and spending time with family and friends.


Emily Thompson

Registered Dental Hygienist

I have been in the dental field for over 13 years. I joined Dr. Koo’s dental team in 2016.  I worked as a dental assistant for 5 years before returning to school to become a Registered Dental Hygienist, graduating from Carrington College in 2009. I find my work as a dental hygienist very rewarding. I love to share my dental knowledge and enjoy working with all patients, especially children. When I am not in the dental office I enjoy spending time with loved ones, working out, cooking, traveling and escaping to the family cabin in Aptos with my dog Chile. 

Alisa Barry

Registered Dental Hygienist

I joined Dr. Koo’s dental team in 2016.  I have over 15 years of experience in the dental field. I graduated from dental assisting school in 2001 and then went straight into dental hygiene school while still working part-time as a dental assistant. In 2003 I graduated with my AS Degree in Dental Hygiene from Foothill College and have worked in private practice ever since. I love treating and educating patients on all aspects of their oral health.

I have been married for 8 years and have 2 wonderful children. In my spare time, I enjoy spending time with my family and friends.
