Changes due to COVID-19/Coronavirus

Due to the current situation with COVID-19, we are offering TeleVisit appointments to our patients. TeleVisits are two-way video and audio calls with your provider that replace face to face appointments.


We will be doing TeleVisits on all days except Tuesday and Friday mornings starting March 23, 2020. We will continue to offer face to face appointments on Tuesday and Friday mornings.

Please call our office at 214-547-7557 or email us at [email protected] for more information on how you can set up a TeleVisit with us.


Our first priority is the safety of our patients and staff members. We will continue to follow the health and precaution guidelines given by our local health departments as well as the CDC.

Together, we can overcome this challenging time!
