Genisys Credit Union, headquartered in Auburn Hills, Michigan, has done something most brands never do with athlete sponsorship: it kept renewing. What started as a single partnership with Detroit Lions tight end Sam LaPorta has become a multi-year, two-athlete program that Genisys has renewed and expanded every season since 2024, adding Lions wide receiver Isaac TeSlaa in 2025 and renewing him again in 2026.
