St. Croix Sensory is an industry-leading sensory evaluation laboratory headquartered in the St. Croix River Valley of Minnesota.

Founded in 1980, Charles McGinley established McGinley Associates, PA, an environmental pollution control consulting business, with specific expertise and focus on control of nuisance odours.

In 1993, with the direction of Donna McGinley, St. Croix Sensory was formed as an independent, third-party odour laboratory providing accurate measurement of odour perception. St. Croix Sensory’s influence on the environmental industry grew with the development of the AC’SCENT Laboratory Olfactometer in the 1990’s and the Nasal Ranger® Field Olfactometer in the early 2000’s, providing key advancements in odour measurement.

In 2023, St. Croix Sensory has opened its first international office in Toronto, Ontario, providing the first independent odour laboratory in Canada.
