AMS Inc. was founded in 1970 by Mr. Paul Simonson. The company was founded with the philosophy of providing top quality janitorial services through sound management principles and technical advances. This philosophy has allowed us to satisfy hundreds of customers allowing for tremendous growth for AMS. This growth has resulted in several million square feet of facilities to be maintained daily in retail, office and institutional buildings by trained professionals. Since 1970, the company has grown exponentially. We now serve customers in North Dakota, Minnesota, Montana and Idaho. We have a management structure that ensures the ability to effectively manage and still be very responsive to our customer’s needs. John Simonson serves as President in Idaho, Tom Greene serves as Vice President in Fargo, North Dakota and Dan Harnist is the Regional Manager based in Minot, North Dakota.
