Brian Allen, MD, FAAP, is a board-certified pediatrician who specializes in pediatric infections and antimicrobial stewardship — using the correct medication effectively in dosage and time. He helps patients and their family treat and manage neonatal and congenital infections; infections of the bone, joint, skin and soft tissue; meningitis and other infections in the central nervous system; and community- and hospital-acquired pneumonias.

Allen emphasizes being an informative, welcoming presence for children and their families who takes time to explain the ‘why’ behind an approach. He is excited to join a team that is fully devoted to putting the health of the child in our area first.

An avid baseball and sports fan generally, Allen is married and enjoys hiking with his wife and dogs Buddy and Mabel, and spending time with their cat, Poppy. He also plays pickleball and ultimate Frisbee when he has time.
