A proud Vietnam veteran, Curtis served in the United States Marine Corps. After his military service, he owned and operated Form and Pour Concrete for over 40 years. He specialized in colored and imprinted concrete and was known for his craftsmanship and strong work ethic. Curtis was a kind and generous man who helped others freely, believed in earning what you had, and was known by everyone as a genuinely good guy.

Curtis loved the outdoors. He was happiest on his property working in the woods, mowing, moving dirt, hauling logs with his Bobcat, splitting firewood, and stacking them perfectly. He truly enjoyed riding his Harley, heading to the Caribbean for some scuba diving, flying his para plane, skydiving, driving his 1970 Corvette, or just sitting at his beautiful pond.

Curtis had a strong and loving presence, and those who knew him remember his strength, his generosity, and the steady guidance he offered to those around him.
