“Grey’s Anatomy” star Patrick Dempsey H’13 appeared on The Ellen Show last week. After a decade of portraying fictional Bowdoin grad Derek “McDreamy” Shepherd on television, Dempsey — a Lewiston native known for his philanthropic work in Maine — was awarded an honorary degree from the College during Reunion Convocation last June. Dempsey gave a shout out to Bowdoin on air.
