Year in Review: Meet the class of 2013

New Doctors for 2013

Some of the doctors who joined ADC in 2013.

The past year has been an exciting time of change for The Austin Diagnostic Clinic. We welcomed many new faces at the clinic, including a vibrant class of experienced and knowledgeable physicians.

Doctors in a variety of specialties have joined ADC, especially with ADC’s expansion into Steiner Ranch in west Austin.

Most of ADC’s new physicians have been seeing patients in Austin for months, but some are starting in December.

From allergy to pediatrics and rheumatology, we’re so happy to have them here!
