The purpose of this basic qualitative research study was to investigate the leadership style that student affairs leaders practiced and whether or not the leadership style contributed to the support of the programming and resources for undergraduate lesbian, gay, bisexual, and transgendered (LGBT+) students at public, four-year institutions. The literature gap included how student affairs leadership's role in supporting and retaining undergraduate LGBT+ students remain unknown. The literature is also unclear on how student affairs leader's leadership style impacts LGBT+ students. The study focused on three leadership theories including, transformational, transactional, and servant leadership. The study's significance was to expand on how student affairs leader's leadership style influences how they offer programming and support to LGBT+ students within their respective campuses. This study sought to answer the question, How does the leadership style of student affairs leaders determine what campus programming and resources contribute to the support of undergraduate LGBT+ students at public, four-year institutions? The study sample consisted of 15 student affairs leaders at 15 different four-year institutions. Each of the 15 participants was in an assistant director or higher position at the time of the interview. The data was collected through semi-structured, online interviews to identify the participant's leadership styles and how they provide programming and support to LGBT+ students. The data analysis supported transformational and servant leadership as the more effective leadership styles for providing quality programming and support for LGBT+ students. The participants who identified as transformational or servant leaders were also more engaged with LGBT+ students. In contrast, the transactional leaders were more focused on the larger scale of what works for the institution, not necessarily for the student.
