Culinary Medicine Programming

Medical Student Programming

Discussions are underway with the Geisinger Commonwealth School of Medicine to launch Culinary Medicine as an elective course. This month-long clinical elective will be a collaboration with Geisinger’s Nutrition and Weight Management department. Students will split their time between Nutrition and Weight Management, where they will explore counseling, surgical, and medical interventions, and Culinary Medicine, where they will attend classes as students and ultimately facilitate community classes.

Medical Professional Programming

Professional classes are held at least weekly for residents and fellows at this time using the teaching kitchen on the Danville campus. Classes are not offered in a series format, rather, they are available for registration individually. This allows for ever-changing rotation schedules and allows the physicians to take classes which are relevant to their practice area.

Community Programming

(Pre-COVID, standard operations) Community classes are offered in a series of four (4) classes to any interested adult. This includes community members, patients, and employees. Classes are typically offered on consecutive weeks and may be held in the daytime or evening. Weekend classes typically offered monthly.

(Current/ COVID operations) Due to changes in operations related to COVID19, community classes are being offered to employees only at this time. Employees are required to complete a daily symptom-checker and report any COVID19 exposures prior to class. Class capacity is minimal with social distancing and masking strictly enforced. Classes have also been switched to a virtual format at points.


The Culinary Medicine program is approved as an activity which counts towards MyHealth Rewards, an incentive program to receive an insurance premium discount through the Geisinger Health Plan. MyHealth Rewards considers an individual’s health metrics and lifestyle choices, then provides resources to help them meet their goals. Other healthy activities which are part of the program include dental visits, weight counseling, gym and sport reimbursement, yoga classes, and more. Participants who complete a community series of four (4) or more Culinary Medicine classes receive a credit towards the premium discount.


The main challenge to date has been securing a reliable and optimal kitchen. Geisinger does not yet have their own teaching kitchen facility, so have been reliant on a local college’s teaching kitchen and a small demo-style kitchen located on Geisinger’s main campus in Danville, Pennsylvania. The college has been an excellent partner; however, kitchen availability is limited. Geisinger’s demo kitchen can only hold a small number of participants as space and appliances are limited.

Other challenges have included attendance and recruitment. While many classes are full, there is unfortunately a high no-show and cancellation rate. Recruitment has been difficult as marketing efforts and resources have been limited. Additionally, no volunteers or support staff are involved in daily operations. This puts logistical limitations on the number of classes which can be offered.


Funding is provided through grants and charitable donations. Other revenue-generating options to create a more sustainable model are being considered.

Research and Publications

No research publications at this point in time.

Survey data is collected from participants, including learning objectives and outcomes and attitudes towards cooking and nutrition. Geisinger developed their own documentation and survey utilizing internal research resources, but also offer Health Meets Food’s program survey and questionnaire to contribute to the national data pool as able.


Efforts to create an interactive social media page are underway, in order to engage past, current, and future participants.
