This is Mason.

Mason is four years old. Like other boys, he likes playing outside, squabbles with his sister and builds rocketships with blocks. He also has sensory processing disorder, which means he reacts to sensory stimuli differently, and he undergoes therapy to help him cope with these stimuli.

I met Mason one morning during his hippotherapy session at Chastain Horse Park. Having met his therapist Brent on a previous assignment for The Atlanta Journal-Constitution, I had originally thought about working on a story about hippotherapy — but after I met Mason, I wanted to know more about him.
Mason’s mother Carol is an occupational therapist, and she was very open and candid about her son and the disorder. She let me follow Mason for another hippotherapy session, and then for an occupational therapy session in their house. On my fourth visit with Mason, I spent the entire day with him — all the way up to bedtime.
