Greg, Thomas and Dean met on a cosmic collision course, in what can only be described as destiny. From completely different backgrounds but with one common interest… science.
The three men had a vision, and a paper napkin.
That vision was to help their community, and others just like it, by building a lab capable of testing for the contaminants that plague the environment. The worst among those contaminants being PFAS/ PFOS, known to be cancer causing and environmentally destructive.
What better place to build such a lab than directly on a former air force base whose firefighting foam training poisoned the surrounding land and water.
With their lab, Enviro Lab Services, being established in 2020, their vision is now a reality.
Enviro Lab Services is on the forefront of testing technology and will continue to push the bounds of science and knowledge.
Gregory Rosenhauer’s Bio
Greg was born and raised in Michigan. He attended Oxford High School and graduated at the top of his class while enjoying extracurriculars like cross country, lacrosse, and martial arts.

Starting at the end of his freshman year, Greg joined an organic chemistry research lab where he worked extensively for three years during his time at Wayne State. This research experience included a wide variety or organic synthesis, purification, and characterization methods.
During this time Greg also spent a summer as a chemistry intern for Dow Agrosciences working on organic chemistry projects.
After obtaining a Bachelor of Science degree in chemistry, Greg attended graduate school at the University of Michigan. While studying chemistry at U of M, Greg performed research on various topics including organic synthesis, materials chemistry, physical chemistry, and analytical chemistry. Greg received his master’s degree in chemistry from U of M in 2018.
In addition to science, Greg enjoys the outdoors and frequently goes kayaking, fishing, boating, hiking, and off the grid camping. Greg’s passion for chemistry and love for Michigan has motivated him to improve the health and safety of the communities that live off the resources of this state.
