Best pediatric GI in the metroplex and we’ve been to a lot. She’s the first one to actually make a difference for my child. Found her when a healthcare professional at a hospital told me about her. That speaks volumes in itself. To top it off, she actually called with my son’s results. One of the only times a physician has actually called to discuss results. Sweet, caring office staff as well. A true gem of a doctor!

Incredible specialist! Very personable and thorough. Worked at diagnosing what was going on with my daughter right away and started her on meds to help ease many of her GI issues. Would recommend her to any parent seeking a pediatrics GI specialist.
