Melissa Nystedt

Vice President of Programs

Melissa’s career arc has been focused on empowering, equipping, and leading talented program staff to achieve organizational goals. She believes wholeheartedly in the impact that strong, professionally supported mentoring relationships have on both the mentor and mentee, and that girls today need a network of allies and champions to help them achieve their individual goals.

Successful mentoring requires heart and science and Melissa brings both to the table. Melissa began her career as a case manager for specialized foster care families and has always had a passion for supporting young people. Prior to joining the Big Sister Boston team, Melissa spent more than a decade with Big Brothers Big Sisters of Eastern Mass, leading the Program Match Support Team and driving research-based best practices that yield quality results. As a continuous learner around issues of racism, power and privilege, Melissa is excited to bring that passion to Big Sister’s ongoing commitment to diversity and inclusion, and explore how it intersects with mentoring relationships, staff, and the broader community. Prior to entering the mentoring field, Melissa holds a Bachelor’s degree in Social Work from Gordon College.
