Michelle Gallas is an assistant professor and outpatient pediatrician who has worked caring for Austin's most under-resourced and disadvantaged since 2006. Her patients are medically and socially complex, and many are recent immigrants or refugees. Gallas is the lead pediatrician for CenteringParenting at CommUnity Care, the safety net clinic system for Central Texas, and has been running groups since 2009. An interesting fact is that all her groups have been in Spanish as there is a large Hispanic population in Austin (we have never had a group with English-speakers only!). Gallas is passionate about resident education and supervises Dell Med’s pediatric residents and medical students at the program’s primary continuity site, East Austin CommunityCare Health Center.
