Ethan Zohn and Jenna Morasca have reached another milestone together.
After getting a stem-cell transplant as part of his ongoing battle with Hodgkin’s lymphoma, Zohn, 38, was by the side of longtime girlfriend as she graduated Wednesday from Columbia University with a masters in Counseling & Clinical Psychology, with an emphasis in substance abuse.
“Through over three years of blood, sweat, tears, heartache, bewilderment, flashes of genius and insight, filming our now Emmy-nominated show Everyday Health, filming Amazing Race, stem cell transplants, two years of Ethan’s cancer treatments and sleepless nights, yesterday I graduated!” Morasca, 31, said on Thursday.
A healthy-looking Zohn – who is smiling in a photo of the couple – expresses how “proud” he is of his significant other. “To see her battle through all sorts of challenges and still find her passion for academics is such an inspiration,” he tells PEOPLE. “Plus, now I don’t have to pay for therapy.”
