Pre-Newborn Care

You may schedule a "meet and greet" appointment to ask any questions you have regarding the birth of your baby and what to expect.

Our pediatric providers are more than happy to meet with first time expecting parents before your child is born. This helps you and the provider to get to know one another, and to see if the pediatric provider is right for you and your baby.

Please contact our front office to schedule the "meet and greet".

Well-Baby / Well Child Check-Ups

Proper check-ups help ensure total wellness of your child. Newborns and infants need frequent check-ups during their first 2 years of life to ensure that they are growing and developing on track. Appointments are readily available. In addition, we will contact you as a friendly reminder when your baby is due for his or her next check-up.

Well-Baby / Well Child Check-Ups

During a routine well-baby checkup, your baby's height, weight, and head circumference will be measured. A complete physical exam will be performed, and anticipatory guidance will be provided to help you prepare for the next stage of your child's growth and development.

As your child grows, additional well-child visits include developmental screenings, routine vaccinations, growth monitoring, dietary guidance, parenting tips, and screening blood work when appropriate.

We follow the American Academy of Pediatrics (AAP) guidelines designed to provide comprehensive health supervision from infancy through adolescence.

Taking your child to the doctor only when they’re sick often isn’t enough to ensure lifelong health. The AAP established a recommended schedule of preventive visits (see below) so parents can anticipate upcoming milestones and discuss important topics with their pediatrician. These visits create opportunities for proactive care, early intervention, and strong doctor–family partnerships—the foundation for a healthy future.

Schedule of Well-Child Visits:

2 months, 4 months, 6 months, 9 months, 12 months, 15 months, 18 months, 24 months (2 years), and annually thereafter for a health supervision visit. Each visit includes a physical exam, growth assessment, developmental screening, and an academic and behavioral check-in to support your child’s overall well-being.
