This study is positioned to contribute to our growing understanding of how COVID-19 has impacted our students and the individuals tasked with promoting their mental health and wellness. The overarching aim was to understand the lived experiences of middle school professional school counselors (PSCs) in addressing student mental health, during the COVID-19 pandemic, after a return to in-person instruction. The study strived to learn, if and how, the PSC's role has changed since returning to in-person instruction and to gauge the kind of support, if any, that they received with their counseling program. The researcher utilized convenience sampling from the Counselor Education and Supervision NETwork-Listserv, the American School Counselor Association listserv and Facebook. The study involved interviews with 10 participants who were employed as a middle school PSC, served in at least the fourth year as a PSC, held a master's degree in counseling, and had internet access. The researcher used Giorgi's descriptive method of phenomenology to analyze the data, which yielded three themes and three subthemes: (1) Awareness and Psychoeducation on the Mental Health Impact of COVID-19, (2) Adapting to Meet the Needs of Students (Utilizing Innovation; Structure and Intention with Direct Service Delivery; Shift to Reactive Services), and (3) Emotional Impact of Being a Helper During the Pandemic. The findings provide stakeholders, PSCs, and school counselor educators with a deeper understanding of factors related to addressing student mental health after a return to in-person instruction and how to better support PSCs in addressing these mental health concerns.
