Had a great Cleaning Session with Olivia. Highly recommended. Also as usual Dr. Tsang's concern for his patients is refreshing. It has been a pleasure for me and my family to work with Dr. Dubin and Tsang for over 15 years. The office staff is excellent and very caring to ensure all is in order with insurance, billing, etc. Very clean office and top of the line, air purifier and other Covid prevention procedures.
