Sean Callahan
Assistant Project Manager

Who, living or dead, would you like to eat dinner with the most? And why?
Muhammad Ali. He was an inspiration to people around the world, was a civil rights icon, received the Presidential Medal of Freedom, not to mention being the Heavyweight Champion of the World, to name only a few of his accomplishments! To experience some of that fiery passion and drive firsthand, while enjoying dinner, what more could you ask for?
How did you get into construction?
My father was a plumber and then a building manager for most of his career. Being by his side to constantly learn how to build things, problem solve, and fix things was something that I always enjoyed as a child and still enjoy now. For me, getting into construction was the natural course of things.
Who or what inspires you?
My biggest inspiration comes from the people that I meet/am around every day. Those who handle the curve balls of life yet continue to wake up early each morning and execute without missing a step.
What is one thing on your bucket list and will you accomplish it?
Becoming a published author. I plan to accomplish it but don’t expect to be any Stephen King!
