Longtime ABC News medical expert Dr. Timothy Johnson was honored at AccesSport America’s annual leadership luncheon at the Millennium Bostonian Hotel. Twenty years ago, Johnson highlighted AccesSport America on “Good Morning America” and the organization, which helps people with disabilities participate in sports, suddenly got a lot of attention. Also at the luncheon were Boys & Girls Clubs of Greater Boston CEO Josh Kraft, “Chronicle” host Anthony Everett, movie producer Dorothy Aufiero (pictured with, from left, Johnson; 9-year-old Tycho Dickerson of Arlington, the organization’s athlete of the year; and Ross Lilley, founder and executive director of AccesSport), and John MacNeil of Moody Street Pictures. . . .
