Why Choose Us

Why Choose Us

At Nemours Children's Health, Newark, we see patients for primary care medical needs like well-child checkups, sick-child care and immunizations, from birth until 18 years old. We offer extended hours that are more convenient for before- and after-school needs.

Your Child's Patient-Centered Medical Home

Our practice has been awarded Patient-Centered Medical Home™ (PCMH) Level 3 Recognition by the National Committee for Quality Assurance (NCQA). As part of our “medical home,” your child's primary care provider leads a care team dedicated to addressing your child’s comprehensive health care needs — arranging care with other qualified professionals as needed. The care team may include our doctors and nurses, care coordinators, psychologists, social workers and/or lactation consultants.
