Senior Vice President of Sales

Kevan began selling insurance in 1992, and to this day, he is still redefining the sales industry into an experience of mutual trust and education. The desire and pursuit of becoming a trusted advisor has always been Kevan’s ultimate goal. He creates a stress-free process by educating clients and ultimately empowering them to make informed decisions for their families and businesses.

This ability, along with a self-starter attitude and strong customer rapport, has earned him Texas Monthly Five Star Home & Auto Insurance Professional for ten consecutive years.
