Struggling with the lack of success in attracting students from underrepresented groups into the mathematics major, the Department of Mathematics & Statistics at Pomona College slowly moved away from a deficit model (e.g., lack of preparation among students) to focusing on the experiences of all of the students in the department. I will discuss the successes and challenges of a few of our concrete cohort programs as well as the role of collaboration, community, and climate in expanding access to educational opportunities in statistics, data science, and the mathematical sciences more broadly.  Additionally, I will provide specific ideas and strategies for making the classroom accessible and engaged.
