Humble Beginnings


Don Freeman had toiled with the idea of owning his own business for sometime, after witnessing his father, John Freeman, pilot a successful sheet metal/mechanical company known as Freeman Metals. Don's dream came to fruition in July 1995 when the doors of Interstate Mechanical and Millwright Inc., IMMI, opened in Spartanburg South Carolina.

We welcome Seth Freeman, Jason's son, who is our latest addition to the family legacy.  He proves that welding is truly in the Freeman blood.

Today, nearly 25 years later, Jason Freeman, Don's son, keeps his legacy alive by standing by his original mission statement: Provide versatile big corporate capabilities with dependable small business values. Interstate Mechanical and Millwright Inc.,IMMI, now provides services throughout North Carolina, South Carolina and Georgia and have come to be known as the company that goes the extra mile to leave their clients with the most positive experience possible.
