Family Member Quote

“Dr. Schneider is a remarkable pediatrician, specializing in adolescent care, with the courage to talk straight to parents and to make referrals as needed. She suggested two options for our son and was very honest about their strengths and weaknesses. It was her referral to the Eating Disorder Clinic at the Hospital at Princeton that finally set us on a path that resulted in success for my son. Throughout that process, she was thorough in her medical evaluation, insightful in her analysis, and caring in her communication with both child and parents.”
