The Triangle Area Network (T.A.N.) TAN is a full service clinic providing comprehensive and primary care for all individuals in Southeast Texas, including the under-insured and uninsured. T.A.N. also operates a food pantry. Our annual food drive helps replenish canned items. On a monthly basis, church members sign-up and prepare lunches for patients traveling to Galveston for treatment. Volunteers are also needed to assist T.A.N. clients with transportation to Galveston.
