As pediatricians, we aspire to provide the best possible anticipatory guidance to promote the optimal health, growth, and development of your child. We do this by applying the principles of evidence-based medicine and the guidelines of the American Academy of Pediatrics to the unique needs of each individual child and family.

Centennial Pediatrics is now located in its own free-standing state-of-the-art medical facility off Highway 121 and Independence to provide the highest quality medical care to the Frisco, North Plano, Allen, McKinney and the surrounding communities. See our new address and directions.
