Open Door Clinic

What Open Door Clinic does

Open Door Clinic is a nonprofit free health clinic founded in 1991 and headquartered in Middlebury, Vermont, providing no-cost medical and dental care to uninsured and underinsured adults in Addison County. The clinic determines eligibility based on insurance status (uninsured) or under-insured status (defined as deductible exceeding 10% of gross annual income), and sees patients by appointment at weekly Tuesday evening clinics and selected Friday mornings at 110 Porter Drive. Beyond primary medical and dental services, it offers health insurance enrollment assistance, financial aid, transportation support, community resource referrals, and a dedicated Outreach Program targeting Latin American migrant/immigrant workers and Caribbean H2A seasonal workers at local orchards, with bilingual (English/Spanish) service delivery.

The clinic operates a hybrid paid-staff-plus-volunteer model: 1–10 paid staff are supported by 137 volunteers contributing over 3,700 hours in 2025, anchored by an Executive Director (Heidi Sulis) and a Volunteer Medical Director (Dr. Linn Larson). Technology footprint is limited to a WordPress website, bilingual Instagram (@opendoormidd), Facebook fundraising pages, YouTube videos in multiple languages, and bilingual newsletters — these function as community outreach and donor-engagement tools rather than service-delivery platforms. The clinic's signature non-clinical initiative is "The Most Costly Journey," a graphic medicine anthology co-developed with Vermont Folklife Center, UVM Anthropology, and cartoonist Marek Bennett, which was selected for Vermont Reads 2022 and the Library of Congress 2022 National Book Festival.

The business model is a donation-and-grant-funded nonprofit: services are provided free of charge, so there is no fee-for-service revenue. Funding sources include individual donations, Facebook/Instagram fundraisers, Venmo (@OpenDoorClinic), stock gifts, annual appeals, and grants from entities such as Farm Credit East ($25,000 Lipinski Award in 2024), Vermont Community Foundation, United Way of Addison County, and The Pad Project. ODC is a member of the Vermont Free & Referral Clinics coalition alongside partners including UVM Extension, Bistate Primary Care (an FQHC), Vermont Care Network, and Champlain Orchards.
