Founded on January 24, 1990 A group of green industry professionals decided their companies, and others like them did not have representation by any existing association, thus forming the Association of MontanaTurf & Ornamental Professionals (AMTOP).

During the conference of 2007, the membership voted in the additional ‘P,’ adopting it into the by-laws, forming the Association of Montana Turf, Ornamental & Pest Professionals (AMTOPP).

Today, the members of AMTOPP include a large array of disciplines within the private and public sectors of the green industry, in Montana.

The Board of Directors strives to keep the association moving into the future while maintaining the founding members’ vision.
