About

Bio

Enter your bio...I received a BA in Biology at Brandeis University in Waltham, MA. I attended medical school at Boston University and trained in pediatrics at the Floating Hospital for Children at Tufts Medical Center in Boston. I have practiced high quality pediatrics in an outpatient and inpatient setting for the past 12 years in the suburbs of Boston. I have been the health consultant to many public and private schools. I have served on the Board of the Independent Physician Association at Emerson Hospital in Concord, MA and helped in establishing the medical home, assisted in electronic medical integration and representing physicians in their contracting with major insurers. I am well versed in all aspects of pediatrics including behavioral issues.

Specialties
Doctors may have more than one area of specialty interest. Board certification in a specialty area means the doctor has completed formal training and has practice experience in that specialty, and has passed the certification examination from the corresponding accredited medical specialty board.
