Ben Zimmerman Director

Feeding Specialist BS, MS in Psychology with an Emphasis in Behavior Analysis


Ben has been working exclusively in pediatric feeding for the last 14 years. His job history includes working at the Kennedy Krieger Institute (affiliated with Johns Hopkins) in the Feeding Disorders Program. During his tenure at KKI, he worked as a feeding therapist in the Inpatient Feeding Disorders Unit, where children and babies between 9 months and 11 years of age were treated for severe food refusal. He also worked in the Outpatient Feeding Disorders Program doing feeding therapy with a variety of cases. This included doing clinic evaluations to determine whether a child was appropriate for the program, as well as determining where they belonged in the feeding program if treatment was advised.

After working at the Kennedy Krieger Institute, Ben decided to open his own feeding clinic (the Los Altos Feeding Clinic) in order to work on advancing his own feeding protocols. He then became the director of the Feeding Clinic of Los Angeles.

Many procedures that Ben has developed are also being used at some of the bigger feeding clinics, which include the Marcus Autism Center in Atlanta, the Monroe Meyer Institute in Nebraska, and the Kennedy Krieger Institute.

Ben is also interested in training other professionals who work in feeding. He has taught a number of advanced seminars about using a behavior based approach to feeding.

Ben works from a behavioral perspective, although from his experience working in a multidisciplinary team at KKI, he has learned that other disciplines must be taken into account when conducting feeding therapy.
