We appreciate your business and will meet with you as soon as possible.

We are open Monday and Tuesday from 8 am until 7 pm and Wednesday thru Friday from 8 am until 5 pm. Our phones open each day at 8 am. A physician is usually in at 8:30 am Monday thru Thursday and at 10 am on Friday and 9 am on Saturday. There may be slight adjustments to these hours so please confirm with our staff. For your convenience, we are also open on Saturdays from 9 am until noon. After hours, we can be reached for urgent matters and our answering service will direct the call to the physician on duty. We ask that you call our office prior to going to the ER, urgent care or retail clinics.

To protect children from a number of potentially serious diseases they should receive vaccinations recommended for them by the American Academy of Pediatrics and your Hahn Pediatric Group healthcare professionals. The proper vaccines prevent your child from contracting a serious illness and are often mandatory for admittance to school. If your child is not completely vaccinated or if you have questions, please ask one of our representatives for more information.
