GPM Health and Life Insurance Company is known for serving federal employees, military families, and seniors with Medicare Supplement, life, final expense, whole life, and term life coverage. The company traces back to 1934 and is part of the GPM Life group, a mutual organization owned by its policyholders rather than shareholders, with a home office in San Antonio, Texas. GPM Life carries a B++ (Good) financial strength rating from AM Best. Because GPM does not run a member self-service website, you handle claims, billing, and policy changes by phone or mail rather than through an online portal.
