Provide quality research, critical communication, and timely and accurate reporting, building trust that results in long term relationships and a spirit of partnership.


With twenty-five years of experience in agricultural research, we opened Lange Research and Consulting, Inc. in January 2014 in Fresno, California (EPA Region 10), the heart of the Central Valley, where rich soil and long warm summers give us the ability to grow a diverse assortment of crops. 

In 2016 we opened our Florida research facility in Winter Garden, Florida (EPA Region 3), with field and greenhouse study capabilities.  With this new location we offer additional growing periods and another regulatory region to further fulfill our clients' needs. 

We have recently expanded our study management capabilities with the addition of two senior study managers, Fred Rice and Alex Gibbs.  Our team manages projects in Residue Chemistry, Environmental Fate, Pollinator Risk, and others, in the United States, Canada, and Central and South America.‚Äč
