Since 1989, EnviroScience has supported environmental design and regulatory requirements servicing federal, state and municipal governments, as well as industrial, engineering and private clients. Headquartered in Northeast Ohio, EnviroScience has assembled a comprehensive team of biologists to provide environmental services throughout the United States and Canada. The company was created with the concept that a small, specialized biology firm could offer cost-effective, high-quality services by eliminating the overhead of a larger parent company. This concept still holds true today, as our scientists explore the latest in environmental legislation and regulations and incorporate the most up-to-date technology to gather and report data.

EnviroScience has grown to more than 130 employees and four office locations. It has been consistently recognized in the regional Weatherhead 100 Awards for its outstanding growth and plans to continue this growth.

Despite tremendous growth, our services remain tightly focused and technically comprehensive. Starting as a bioassay laboratory, the company gained a reputation for providing quality testing at competitive prices. As business expanded into surrounding states, clients began to request additional biomonitoring services. In response, EnviroScience formed a very specialized, multi-disciplinary staff of highly trained biologists. Our professionals offer a wide range of ecological services including aquatic surveys, wetland delineations, terrestrial surveys, lake management, and mussel surveys. All disciplines have been successful in working together to provide an extensive matrix of environmental services.
