Marcia Stanley, age 70, is a lifelong learner and teacher. When she’s not boxing three times a week at Rock Steady Boxing, you can find Marcia singing with her Tremble Clefs singing group, walking with her friends, swimming laps at the YMCA, or coaching private swimming lessons. Marcia has always communicated with ease. And for the past three years, that has still been the case. But since receiving news of her diagnosis of Parkinson’s disease, these last couple of months have proved challenging.
