Commonwealth Pediatrics
About
Commonwealth Pediatrics is a pediatric primary care practice in Stoneham caring for children from birth through age 22. Its board-certified pediatricians and nurse practitioners aim to be a medical home where families are known, supported and respected, and they help children reach goals related to school, sports, friendships and family. Visits cover well checks, urgent sick appointments, virtual visits, behavioral health and after-hours care.
The practice was co-founded in 2015 by Dr. Michelle Lock and Dr. Angelica Espinosa-Louissaint. As members of the Pediatric Physicians’ Organization at Children’s and the Boston Children’s Hospital Primary Care Alliance, they collaborate with nearly 500 pediatric providers statewide and with Boston Children’s specialists. That network lets the office treat many ongoing conditions on site, including acne, ADHD, allergies, anxiety, concussions, depression, headaches and simple orthopedic injuries.
