Headquartered in Green Bay, Wisconsin, we find ourselves deeply interwoven in the heart of America's Dairyland.  Our roots took shape in the Green Bay Chamber of Commerce Incubator close to Lambeau Field.  Over the next 10 years, we grew and relocated to the east side of Green Bay in 2000. The new site started with 8,000 square feet of laboratory and office space.  In the fall of 2011, we again expanded, adding 15,000 square feet, tripling the size of the laboratory and adding dedicated space for a training center, a lab for special projects and office space for administrative needs.  

Cherney's Proficiency Programs
 
Programs run quarterly and are prorated if an individual chooses not to participate in all four quarters. Participants may analyze the test items for any, or all, of the tests specified for the given program.  Cherney will work with our customers to determine if their internal products and methods are comparable to our programs and matrices and help work through any troubleshooting that may arise. Should an unsatisfactory or unacceptable result be produced, customers may choose to participate in our Cherney Recheck program as well.
 
In 2014, our in-house training center was opened to customers and industry partners to fulfill founder Debra Cherney’s dream of providing answers and improvements to laboratories through information transfer and technical training. Following this vision of “Culturing Knowledge Through Training and Education”, our first course, Introduction to Food Microbiology – The Basics, a practical, hand-on workshop that incorporated lectures, demonstrations and lab activities, was created. Since then, Cherney has continued to expand, offering that meet a variety of different education needs.
