College mental health is at a crossroads. Prevailing approaches that focus efforts on healing individual students are unsustainable given unprecedented demand for mental health services. However, these challenges also present an opportunity for the field of higher education to diverge from that path and begin cultivating university communities where everyone -- not just mental health professionals -- take care of our students and each other. For well-being promoting efforts to reach all students, it is almost a requirement to focus on initiating changes in classrooms and other learning environments in collaboration with the instructors and other academic staff who interact with students on a daily basis. To this end, our Well-being in Learning Environments (WBLE) program creates partnerships with faculty to embed mental health support practices within classrooms, departments, and colleges. Herein, we reflect on six years of relationship-building with faculty, staff, and administrators to support student well-being at multiple levels within our institution, describing the theoretical framework, implementation, evolution, and outcomes of the WBLE program since its launch in 2017.
