Keeping our patients healthy and promoting healthy lifestyles is the mission of every one of our providers at Lewisburg Pediatrics. From the development of infants to treating children of all ages, our staff is committed to serving you and your entire family. 

Since opening our practice over 40 years ago, we have created a caring and private setting to ensure that you and your child are always comfortable throughout your visit. We are strong believers that communication is key to creating a trustful bond with our patients that last a lifetime and leads to better diagnosis and treatment. From the moment you walk in our doors, every one of our staff members, from the front desk to your doctor, is committed to your well-being and giving the best care possible.

One visit to our office will show you why so many of your neighbors rely on us. 

To schedule an appointment, please call 570-523-3264. Please be advised if you arrive fifteen minutes or more past your scheduled appointment time, you may be asked to reschedule. We will do all we can to accommodate requests, however, we must also keep in mind the schedules and acuity of other patients. Saturday morning appointments are available for acute illnesses only.   


It is the office policy to collect payment (including co-pays) at the time services are rendered. Our practice participates with many insurance plans. If we do not participate with yours, we expect payment at the time of service. We will be happy to file your claim for services if you have given us all the required and correct information. Should disputes regarding payments arise, we may require your assistance in communicating information to your insurance company.


Dismissal from our care is at our discretion, and may occur in lieu of excessive debt owed past due dates, repeated missed or tardy appointments without communication, unruly or unsafe behavior, noncompliance with medical advice, or other unforeseen circumstances deemed not to be congruent with office policies.
