Office Hours


The oSTEM at Colorado School of Mines Office Hour Program seeks to provide support and guidance to students who are looking for a listening ear in the LGBTQ+ community.

Participants are encouraged to ask questions, challenge stereotypes and gain self-confidence. The program provides not only sexual identity support to students, but also academic, career, community and personal guidance. Allies and all members of the LGBTQ+ community, including questioning individuals, are encouraged to participate.

Office hours will not be held on days off from school. Please check the oSTEM calendar for any changes or cancellations.

Due to the quarantine, office hours will be held digitally as needed. Most exec members are using the oSTEM discord to host office hours. You can contact us by email or through the oSTEM Discord.
