About Us

LEGEND Technical Services, Inc. (LEGEND) is a woman-owned business offering diversified analytical laboratory testing and industrial hygiene consulting that operates a network of offices and laboratories throughout the midwestern and southwestern United States.

1991

Minnesota Headquarters

LEGEND was established by two former Twin City Testing Corporation professionals with experience in commercial chemical analytical testing and health and safety consulting including remediation design and over-site.

LEGEND opened its first location in St. Paul, Minnesota that houses an environmental laboratory and industrial hygiene consulting group.

1992

Wisconsin Expansion

In 1992, we opened our first expansion office in Mosinee, WI. Nearly ten years later, another office was opened in Appleton. By 2009, we relocated all Wisconsin operations to Eau Claire, WI, where we’ve found a home for the last decade.

1996

Arizona Acquisition

In November 1996, we acquired Bolin Laboratories, Inc. in Phoenix and Tucson, AZ. The commercial microbiology lab quickly evolved into a full-service environmental lab to serve the enormous needs in the region.

1997

North Dakota Expansion

Our rapid expansion continued into 1997, when we opened our Fargo, ND office. The Fargo team quickly established themselves as a leader in asbestos and mold services.

2015

New Building

LEGEND has continued expanding throughout the years relocating our St. Paul laboratory in 2005 and building a new laboratory for the Phoenix, AZ location in 2015.

2016

Cannabis Laboratory

LEGEND becomes the first laboratory in the country to have a validated method for cannabinoids in plant material. In doing so, A2LA accredited our laboratory for cannabis testing to ISO/ICE 17025 standards.
