About Us

MBI has been providing scientific research and education since 1997. We offer a unique skillset, bringing together sound science and education based on extensive expertise and experience. Many of the techniques broadly utilized in standardized aquatic resource monitoring across Ohio and the Midwest were pioneered by members of the MBI team. We bring this expertise to the field, to the classroom, and to all that we do.
