Info

Founded by Dr. Brian J. Strasnick in 1995, Willow Laboratories is a state and federally licensed laboratory that provides responsive, high quality lab work in a time-efficient manner. Since being founded, Willow has grown to become one of the leaders and largest providers of alcohol and drugs-of-abuse testing in the country. We serve a wide range of clients with both qualitative and quantitative results, doing millions of drug tests annually. As a recognized leader in the industry, Willow has made it a vision to categorize testing not as a punitive measure, but as a vital tool in one’s recovery. Headquartered just outside of Boston in Lynn, Massachusetts, Willow sits in a newly renovated 90,000 square foot building and services many of its clients through this location. In addition, Willow maintains local staff throughout Vermont, Rhode Island, New Hampshire, New York, Florida, Ohio, and beyond to further meet the needs of our customers.
