We believe that healthcare is the foundation of a secure retirement. Medicare is one of the most important transitions you will make, and it shouldn't be a source of stress. Our mission is to provide the clarity, expertise, and personalized advocacy you need to choose your coverage with total confidence.

With nearly four decades of experience in the insurance industry, Steve Thomas has served Arizona clients since 1986. After 17 successful years with a national captive insurance company, he chose to become an independent agent — allowing him to provide objective guidance focused solely on his clients’ best interests. In 2026, Steve sold his property and casualty agency, Schaller & Thomas Insurance, to concentrate exclusively on life and health insurance. Through MedigapAZ, he helps Arizona retirees and pre-retirees navigate Medicare with clarity and confidence — ensuring they understand their Medicare Supplement, Medicare Advantage, and coverage options while avoiding costly, lifelong mistakes. Born and raised in Arizona, Steve understands the unique needs of local families transitioning to Medicare. He and his wife Claire enjoy fitness, the Arizona outdoors, and spending time with their growing family. Steve remains committed to serving his community with integrity, clarity, and long-term relationships.

GHW Partners is focused on providing an intentional, elevated experience for the entrepreneurs and producers dedicated to long-term impact.
We were founded on a singular belief: true partnership means creating a space where top leaders receive the strategic support, guidance, and challenge required for meaningful, sustained growth.
