We are currently accepting new patients!

Washington Square Pediatrics is the office of Drs. Sally Roth, Susan Laster, Cara Guenther, and Shannon Fernandez-Ledon. Located in the heart of Brookline, Massachusetts, our small private pediatric practice cares for children from their very first checkup through college graduation and beyond. Watching our patients and their families grow up with us is the best part of being a pediatrician.
Why families choose us
Our patients choose us because they know they will get excellent medical care in a personalized office. We have access to the most up to date pediatric information in the country through our affiliation with Boston Children's Hospital Pediatric Physicians Organization, the hospital's preferred primary care network. Through our affiliation with Harvard Medical School, we stay current on the latest in pediatric medicine.
The relationship between your family and pediatrician is at the heart of our office and this approach is reflected in our practice model. All well visits and any weekday sick visits are scheduled with your pediatrician. You can reach your pediatrician through portal messages or by leaving a message with our staff. Urgent questions after hours or on weekends are answered by the doctor on call. And sick visits are always available when necessary, including Saturdays, Sundays, and holidays. We are here to help.
