Dr. Peter I. Liber started Wheaton Pediatrics in 1987 as a solo practitioner. Today, Wheaton Pediatrics has grown to become one of the area’s most respected pediatric practices with seven pediatricians and two pediatric nurse practitioners, in addition to talented nurses, medical assistants, and administrative and support staff.
