Mammoth is Veteran Owned
Our Mission - Veteran Owned Small Business (VOSB)
Established in 2016 as a Hoosier owned and operated S-Corp, Mammoth Construction is a ground-up General Contractor. Founded by former U.S. Army non-commissioned officer and combat veteran Chief Executive Officer Jason Marlow with lifetime construction management professional and Chief Operations Officer Joe Gaw, they believe in “a commitment to building excellence by inspiring intelligent and tenacious teamwork” throughout every project. Leaders with military grade integrity, well-educated communicators, and experienced contractors make for a safe, quality building experience for customers and designers alike.
Proven Experience - Mammoth's Team
Mammoth’s team members have a wealth of experience stretching back much further than our founding. With the expertise to design and build complex and logistically challenging construction projects, Mammoth Construction has tackled projects from picnic shelters to airports and everything in between.
New turnkey/ground up commercial construction, renovations and buildouts, hospitals, schools, libraries, industrial manufacturing facilities, and warehouses are all well within Mammoth’s wheelhouse and our deep bench of subcontractors.
