Because every child is extraordinary!

E-VISIT UPDATE 4/1/2020:

We hope that you are all staying home and staying safe. This is a difficult and trying time for all of us and we want you to know that we are here for you if you have questions or need an appointment.

We are now able to do  E-visits (Telehealth) in order to continue taking care of our patients and helping them avoid unnecessary trips to an urgent care or emergency room. Please call our office for more information.

Also many parents have been asking if they should reschedule their child’s well visits. We are following the recommendations of the American Academy of Pediatrics (AAP). They say that In light of the pandemic, pediatricians need to continue to provide well-child visits and immunizations for newborns and young children but delay such visits for older adolescents. We are praying for all of you and look forward to seeing you again soon.
