In Person & Telehealth

IN PERSON APPOINTMENTS: Our office requires you to wear a mask at all times. We will provide you with a mask if you do not have one. This is for the mutual protection of all of my patients and my staff. If you have symptoms of cough or fever, or if you have been in contact with anyone with COVID-19, please call the office to arrange a TeleHealth Appointment.

TELEHEALTH APPOINTMENTS: A TeleHealth Appointment is a consultation via smart phone or webcam, which allows you to maintain social distance, protect the older population of our community, and meet with Dr. Tieng from the comfort of your own home. If your visit is not urgent, please call my staff for detailed instructions on how to set up your initial TeleHealth Appointment. You may be asked to install an app on your iOS or Android device to insure that your consultation is private and secure. 

If this is an emergency, please dial 9-1-1 and contact emergency services.
