CHERYL L. CULLINAN, a PhD student in the Department of Learning and Instruction, passed away unexpectedly on Oct. 14, 2022. She was 52.

After earning a master’s degree in secondary English education from Buffalo State, Cullinan served as an ELA and social studies teacher at Kadimah School of Buffalo, an adjunct professor at Erie Community College, and an ELA and SAT instructor in UB’s Upward Bound Program. She was a wife and a mother as well as a coach and academy staff trainer for the Clarence Soccer Club.

“When I think of Cheryl, I think of laughter, humility and wisdom. Cheryl found humor everywhere and shared her joyous spirit generously. She was an eager learner and listener who was humble despite her many accomplishments. Among the most noteworthy of these accomplishments was Cheryl’s ability to forge and sustain strong relationships with students at all levels. Relationships were always her focus—you couldn’t talk to Cheryl without hearing about her family and her students, whom she loved deeply. Her spirit will live in our hearts, and in the hearts of all who were fortunate to know her,” said Cullinan’s doctoral advisor, Julie Gorlewski.
