Evan Riley of Thomaston has been selected to serve a third term as the state ambassador for the Muscular Dystrophy Association. Riley will make public appearances throughout the state, representing children and adults in Maine with muscular dystrophy, ALS and related life-threatening diseases that severely weaken muscle strength and mobility.

Riley was diagnosed with Duchenne Muscular Dystrophy at the age of 2. The illness can affect the muscles of the hips, pelvic area, thighs and shoulders, and later the skeletal (voluntary) muscles in the arms, legs and trunk.

Riley is in fifth grade and his favorite subjects are math and science. He often goes ice-fishing with his family, and has attended MDA Summer Camp for the past three years.
