​Since 1988, our practice has been providing compassionate care to newborns, infants, children, adolescents and adults of all ages, including the elderly. We want you to feel comfortable, respected and delighted with your care. Our doctors and staff listen to your concerns and answer your questions clearly and in straightforward language that's easy to understand. Our goal is to partner with you to improve your health, and we strive to get to know each patient as a whole person. As a result many of our patients have been with us for over 20 years. In fact, many patients have entrusted us with the care of three or even four generations of their family!

Located on the north side of Rush University Medical Center in the Triangle Office Building, we have extended office hours with early-morning and evening appointments available, as well as our acute care Walk-In Clinic Monday through Friday mornings from 7:45 a.m. to 8:45 a.m.

She speaks conversational Spanish but also offers patients the option to use free interpreter services if they prefer.
