Welcome to Our Practice

Welcome to Pediatric Associates, Inc., Your Pediatrician in Fort Wayne, IN

Our mission at Pediatric Associates, Inc. is to provide comprehensive pediatric care to infants, children, and teenagers living in Fort Wayne and the surrounding communities in northeast Indiana and Ohio.

Pediatric Associates, Inc. opened in 1969. In the many years since, our team has established a reputation for providing compassionate, high-quality care in a warm and welcoming environment.

We are conveniently located near a hospital complex. This allows patients to access diagnostic imaging and laboratory testing without leaving the building.

At each visit, children and their guardians meet with our licensed nurses and a board-certified pediatrician. Our nurses perform patient intake procedures and answer questions, and our pediatricians provide time for comprehensive one-on-one appointments.

To accommodate our patients’ busy schedules, our team offers same-day and walk-in appointments, after-hours care, and flexible 24/7 access to physicians. 

Our team also provides sports physicals, well-child check-ups, consultations with expecting mothers, newborn care, lab tests, and nutrition guidance. We believe in conservative, integrative care and follow guidelines set by the Centers for Disease Control and Prevention (CDC) and the American Academy of Pediatrics (AAP).

To access comprehensive pediatric care for your child, partner with our caring team at Pediatric Associates, Inc. To schedule an appointment, call the office or request one online today.
