News No Comments Dr. John McAllister, of Little Rock, has always known that he wanted to work in a field concerning vision, even though he wasn’t always sure what that career would look like. “I was always enamored with the eyes and vision,” McAllister said. “I was trying to figure out my path of what I wanted to do in life, and one day I thought I wanted to be an optometrist. That opportunity got away from me, and the next opportunity was in the field of blindness and vision impairment. When I got into the field, I loved it.”
