Dennis Postema has built a career on a simple bet: relationships scale a business faster than hustle alone. As founder of Postema Insurance & Investments, he grew a single Ohio operation into a multi-state agency by leaning into networking rather than treating it as a side task. Dennis Postema joined Sean Kelly on the Digital Social Hour to break down the networking approach that changed the trajectory of his business.
From there, the discussion widens into comfort zones, stress management, and the mentors — including Brian Tracy — who shaped how he leads. It's a grounded conversation about the unglamorous habits behind sustained growth.
