About Us


The Minnesota Geotechnical Society (MGS) was established in 1969, as an independent, nonprofit organization.  At the turn of 2019, MGS officially partnered with ASCE, becoming Minnesota Geotechnical Society - a Geo-Institute Chapter (MGS-GI).

Our mission stands firm.  We provide a forum for geotechnical knowledge, encourage communication with other technical disciplines, and facilitate networking among engineers, geologists, educators, students, technicians, and contractors.  We strive to connect students to geotechnical professionals for career opportunities and scholarships.

Membership in the society is open to anyone engaged in activities related to civil engineering, engineering geology, soil science, land conservation, and planning.
