Calvin Sulak

INS Marketing Systems

Calvin Sulak is President and CEO of INS Marketing Systems.

Calvin Sulak began his insurance career in 1970 as a field sales agent, becoming a district manager within two years. By 1979, he had formed his own insurance agency known as Best Marketing Systems (BMS). The agency’s impressive sales force sold major medical, life insurance, Medicare supplements, and ancillary products. In the 1990s, BMS officially became INS Marketing Systems and continues to provide exceptional customer service, training, and marketing tools that are vital to the agents and customers they support.

Calvin is proud to have helped launch the first electronic healthcare sales platform, additionally, he previously served on the NAHU advisory council. He also takes great pride in being a hands-on field trainer for new agents and helping them become well-rounded and successful. He and his wife, Roann, have made INS Marketing Systems a second-generation home that includes several of their children working as active agents. The agency has evolved into a one-stop shop providing life and health products of all types, with a close-knit family atmosphere felt by each person they work with.

Calvin and Roann currently reside in Waxahachie, Texas. They have eight children and 14 grandchildren and are focused on living life to the fullest. Calvin and Roann are dedicated to providing life and health solutions that fit both the producing agent and their customers’ needs. Together, they work to ensure a captivated, not captive, partnership.
