Sarah Brazaitis, Ph.D. Faculty Advisor

Sarah has enjoyed serving as OHDCC’s faculty advisor for over a decade. OHDCC started in the early aughts as a small group of students sponsoring a handful of offerings and over the years it has developed into a high performing team designing and implementing dozens of workshops, panels, social gatherings, mentoring and networking events and an annual human capital case competition. Working closely with the students in OHDCC is inspiring and rewarding. They are fun and funny, smart and motivated, and, also, wonderful examples of service – generously sharing their time and wisdom with our Social-Organizational community every day. OHDCC is truly a reminder of the power of teams and of servant leadership. Outside of work, Sarah spends most of her time practicing servant leadership with her favorite team – Buddy, Javier, Mateo, and Grandma She She. (Well, with her two teenage sons, she’s mostly doing the servant part.)
