About Us
Founded in 2003 by Dan Flatten, Core Building Company was built on a foundation of hands-on experience and a passion for craftsmanship. Dan began his career in commercial construction in 1988 and became a general contractor in 1995. After years of working his way up through the trades, he established Core Building Company to bring a higher level of integrity, quality, and collaboration to every project.
With that foundation, Core Building Company was established to deliver exceptional quality and service in commercial interior construction. Over the years, we’ve earned a reputation for precision, integrity, and lasting partnerships. Our expertise spans a wide range of projects, including corporate offices, medical and dental facilities, life science environments, retail spaces, and religious institutions.
At Core Building Company, we believe in doing things the right way, through collaboration, craftsmanship, and a commitment to exceeding expectations on every project.
