Mason Clinic - Pediatrics
Pediatrics specializes in the healthcare of infants, children, and adolescents. Our goal is to provide their patients with the best possible medical care, and parents with preventative guidance, as they follow your child from birth to adulthood.

- Monday-Friday: 7 a.m. to 5 p.m.
Pediatrics
When things get busy, Pediatrics providers team up to make sure all kids needing same-day care are seen. The staff is also available on-call nights and weekends, so that they can help parents determine whether their child needs to be seen immediately at the Hospital, the next day at Mason Clinic, or can be treated at home.
Arriving on time for your scheduled appointment is important in addressing your healthcare needs. Please notify Mason Health as soon as you know you will need to change or cancel your appointment. You are required to cancel your appointment at least one business day prior to your scheduled appointment because of high patient demands. Your ability to schedule future appointments will change because of missed appointments or cancellations.
If you have questions about our No-Show and Cancellation policy, please call the clinic or download a copy of the No-Show and Cancellation Policy as indicated below. Please bring your ID and copy of your insurance card to your appointment.
Reach Out and Read

At each well-child checkup for children from infancy through age 5, our clinicians offer advice to caregivers about early relationships and literacy and give children a new book to take home to build their home libraries. From 2003 to 2024, Mason Clinic-Pediatrics handed out 39,524 books to families at well-child visits.
