Get to Know Our Pediatric Doctor and Medical Team

In 2009, Pediatrics On Demand began as a walk-in clinic, the first of its kind in the state of Illinois. Ayman Rawda, M.D. FAAP, our pediatric doctor, wanted to expand Pediatrics On Demand for the sake of being available for children and families whenever they deemed our services necessary. Our urgent care center for kids is open for twelve hours a day, 365 days a year. As board-certified pediatricians, we can guarantee that children receive the best urgent pediatric care and primary services across the state of Illinois.
