LaGuardia Community College is an international leader recognized for developing and successfully implementing initiatives and educating underserved diverse students. LaGuardia's STEM students are holistically advised by a team of dedicated faculty and staff members from different departments and divisions. As an innovative approach to advisement, students are first connected to an advising team member in their discipline-based first-year seminar and consequently guided by other cross-institutional advisement team members to ensure their continued success. In this article, we share our policies, processes, and promising practices in advising STEM student at an urban public institution. We present arguments that address and support five pillars for student success: 1) the student matters, 2) supportive culture matters, 3) effective communication matters, 4) data matters, and, 5) clear pathways and effective advisement matters. Finally, we present empirical evidence that show positive results in terms of students' retention. Specifically, there was an improvement in the actual Fall 2015 to 2016 return rate of STEM students, from 62.9% to 64.6%. Our scaled practice demonstrates the value of collaborative team-based advisement efforts as supported through professional development can improve community college STEM student persistence when the above five pillars are fully espoused by the institution.
