Geosciences encompass a wide range of career options in extractive industries, geotechnical and environmental consulting, and local to federal government agencies. Students, both undergraduate and graduate, may be unaware of the career options available and may find transitioning from their degree program to the professional workforce a challenge. Many faculty have little professional work experience outside of academic contexts, which can limit the assistance they offer. To address these issues, members of the Western Michigan University Department of Geological and Environmental Sciences Advisory Council (GESAC) created a career development and mentoring program. The goal of the GESAC Mentoring Program is to connect students to alumni mentors across a range of geoscience industries. Access to mentors will help students plan their educational journey, better understand career opportunities, and become a future geoscience leader. Interested students are connected by the program leader to a mentor in an industry relevant to the students' interests. Participating students are commonly seeking work or internship opportunities, advice about choosing program electives and potential career paths, or building their professional networks. Mentors also advise on crafting resumes and preparing for job interviews. A mentor and student might connect a few times or could maintain communication throughout the student's transition to the workforce. Since the program started in 2022, thirteen students have participated with nine now employed or in graduate school. The program is publicized in an internally hosted webpage, through the student-led Geology Club, and in seminar and classroom presentations. The main challenges to sustaining the GESAC program are recruiting dedicated mentors and overcoming students' hesitation to reach out to ask for career advice. Our long-term goal is that every geoscience student will have a GESAC mentor, and that program graduates will be willing to mentor future students of their own.
