Our Story
A trade learned for life
At MRG Construction, craftsmanship is more than work. It is a lifelong passion.
The company was founded in 2014 by Mark Gavigan, a father of three, and built on hard work, dedication, and pride in delivering quality craftsmanship that families can enjoy for years to come.
With over 35 years of hands on experience in woodworking and construction, Mark dedicated himself to mastering the trade straight out of high school. After years in the union refining his skills and learning every aspect of the craft, he chose to build his own company, focused on custom woodworking and personalized service.
Today, MRG Construction is known for high quality custom woodwork, detailed craftsmanship, and a genuine commitment to customer satisfaction. Whether it is custom trim, built ins, renovations, or unique woodworking projects, Mark brings each customer’s vision to life with skill, precision, and care.
