Meet Our Providers

Welcome to Mountainland Pediatrics... we're glad you're here! The American Academy of Pediatrics believes that every child deserves a medical home. Put simply, a "medical home" is a model for delivering healthcare that is accessible, continuous, comprehensive, family-centered, coordinated, compassionate, and culturally effective. We want you to think of Mountainland Pediatrics as your pediatric medical home. Our philosophy of care is child-centered, family-focused, and collaborative. There are so many important decisions you'll need to make throughout your child's infancy, childhood, and adolescence! Breast milk or formula? Circumcision or no circumcision? Belly-button ring or no belly-button ring? Our pediatricians, physician assistants, and nursing staff will always be here as a valuable resource and support system for you throughout your child's formative years. Meet our providers!
