    What Sets Limnopro Apart?

    This company was started because we believed there was a better way to do things than previously done.  Few have the advanced training, experience, background, and technical abilities to advise clients to make sense of issues, and more importantly, to solve problems. We will help you to determine value, objectives, and metrics to evaluate the particular goals you have.  We will work from start to finish to design projects or provide services or advice to meet those goals.

    Limnopro is headquartered in St. Cloud, Minnesota, which is in the central portion of the state.  We provide professional services and consulting primarily to lake rich areas of Minnesota.  We accept biological samples for taxonomic work from all over the U.S.A.
