With an admiring nod to Henry Wadsworth Longfellow, Carissa Greenhow quoted from his poem “Excelsior” and encouraged her fellow graduates to “reach onward and upward” at Macomb’s 89th commencement on May 10. Greenhow, who graduated with an associate of applied science degree from the College’s Physical Therapist Assistant program, was the Most Distinguished Graduate and commencement speaker. Her degree was one of approximately 1,500 awarded by the College at the end of the winter 2013 semester. A Detroit native, Greenhow, 21, intends to transfer to Oakland University and pursue, ultimately, a doctorate in physical therapy. “When I began at Macomb, I thought when I finally walked across this stage I would be finished with my education,” Greenhow told her audience. “But the professors at Macomb have inspired me, like many of you, to continue that journey and pursue even loftier goals.”
