Southlake / Tri-City Management Corp.

Southlake / Tri-City Management Corp., doing business as Geminus Corporation, is a tax-exempt nonprofit organization operating as a federal grant recipient (26% prime grants, 74% sub-recipient grants) in substance abuse prevention, mental health services, and child development programs across Indiana. The organization holds no federal contracts and does not compete in the prime contracting space; instead, it receives grant allocations and sub-awards from federal agencies and state pass-through grantees.

Geminus Corporation's capability portfolio centers on evidence-based prevention and early-intervention services. As a prime grant recipient, Geminus holds a $425,000 five-year Substance Abuse and Mental Health Services Administration (SAMHSA) Center for Substance Abuse Prevention award (CFDA 93.492) running through September 2031 to implement the Geminus Partnership for Success project, targeting underage drinking, marijuana use, and tobacco or vaping prevention for individuals ages 9 to 18 across Lake County, Indiana. The project employs the Strategic Prevention Framework and delivers multiple evidence-based interventions, including Smart Talk cannabis prevention curriculum, Class Catalyst social-emotional learning (CASEL-designated), Be Strong Families Parent Cafes for family protective factors, SAMHSA's Talk. They Hear You. parent engagement campaign, and the Did You Know opioid awareness initiative. Geminus also holds Head Start and Early Head Start grants awarded by the Office of Head Start, with the Head Start and Early Head Start prime grant running through January 2029 and an Early Head Start-Child Care Partnership grant completing in January 2026.

Customer concentration is heavily weighted toward USDA Food and Nutrition Service, which accounts for 46 of the 66 total awards in the source data (covering 91% of the award count). The Department of Health and Human Services agencies — including the Administration for Children and Families and SAMHSA — combined represent a secondary funding stream across substance abuse prevention, mental health services, and child care partnerships. Geminus serves ten distinct federal customer agencies in total.

The sub-recipient footprint dwarfs the prime portfolio. Geminus receives 49 sub-awards (74% of its federal footprint) flowing from the Indiana Department of Education and Indiana Family and Social Services Authority as prime grantees. Sub-award activity has accelerated sharply — 3 awards in 2022 rising to 17 in 2025 and 16 through September 2026 — with monthly recurring allocations from Indiana DOE spanning October 2022 through the present. A January 2026 sub-award from Indiana Family and Social Services Authority funds substance abuse prevention within Indiana communities targeting the general public and high-risk populations; two July 2023 sub-awards from the same state agency fund mental health service delivery. The combined $525.5 million in obligated dollars across the 66-award footprint reflects the scale of annual USDA Food and Nutrition Service allocations flowing through Indiana's state administrator to Geminus as a sub-recipient operating entity.

Performance is based at Merrillville, Indiana 46410, with service area scope encompassing Lake County, Indiana (estimated population 504,612, with demographic composition 70.8% White, 24.6% Black or African American, and 21.3% Hispanic or Latino).
