For my wife, Carol for being a solid rock and support in my career. For my parents, who

continue to teach their sons, no matter how old they get. To my brother, Rick, for showing

me that happiness isn’t achieved, it’s a choice. To my grandparents, for their sacrifices to get

us where we are today, their stories of life in a better time, their bear hugs that seem to get

stronger every year, and baked goods that my mouth waters for at the very thought of them.

My aunts and uncles, cousins, and nieces for always making room in their schedules for me

at a moment’s notice when I come home to visit.
