Bryn Mawr Alum Joins Posse Boston Advisory Board
Bryn Mawr College Posse alumna, Kerlyne Jean (KJ) has joined the Posse Boston Advisory Board, building on years of service as a volunteer and corporate partner, connecting Scholars with professional opportunities.
KJ is a director in PwC’s Health Advisory group where she advises leaders at some of the nation’s largest health systems on operations strategy and enterprise transformation. Since joining the firm in 2015, she’s helped organizations modernize how they deliver care, strengthen operational and financial performance, and improve the experience of the patients, communities and workforce they serve. She holds an MBA and a master’s degree in public health from Boston University. Her commitment to health care was shaped early by her mother’s career in hospitals, and it continues to guide her focus on the people who make health systems work.
Before joining the advisory board, KJ strengthened the relationship between Posse Boston and PwC. She has hosted career exploration events, participated in the first round of Posse’s Dynamic Assessment Process and recruited colleagues to get involved. These efforts introduced Scholars to consulting careers while creating new ways for PwC professionals to engage with Posse.
Recently, KJ hosted Posse Boston’s 2026 Alumni Induction event, welcoming new graduates into the local alumni network as it reached its 1,000-alumni milestone.
Posse Boston Director Yinnette Sano has known KJ since serving as her trainer during Pre-Collegiate Training. KJ’s appointment marks a new chapter in a relationship that began nearly two decades ago.
As an advisory board member, KJ brings the perspective of a former Scholar, a senior health care consulting leader and a longtime volunteer. Her experience connecting Scholars, alumni and colleagues will inform her work supporting Posse Boston.
“Seeing KJ grow in her leadership throughout the years has been such a gift,” says Yinnette. “I have had the privilege of working with her since she was 17 years old. She has always been a natural connector, agile-minded, and so insightful.”
