Covid-19 Announcement

Out of an abundance of caution and in support of the community’s efforts to contain and slow the spread of COVID-19, beginning Monday, March 23rd, all in-person speech, language, and audiology testing services have been suspended at the UNT Speech and Hearing Center until further notice. Online speech and language teletherapy sessions will be available to all patients.

If you would like to transition to teletherapy sessions and have not made arrangements already, or if you need hearing aid services, please call our front office at (940) 565-2262 and we will be happy to assist you. Thank you for your understanding during these unprecedented times. Your health and safety are our highest priority.
