Dr. Stephen Roth, a pediatrician, makes a final inspection of Madison Mann's eye. He decided last year to see patients on Sundays. Only on Sundays. Roth said he has heard horror stories from parents who had to wait hours in emergency rooms on Sundays before their children could be seen and then had to pay hundreds of dollars for putting a cast on a broken arm. Visits to Dr. Stephen Roth's office in Downer's Grove, Ill., usually take about 30 minutes to an hour, often cost only a small co-payment and are covered by virtually every health insurance plan.
