Dr. Batshaw's wife, Karen, is a social worker in the field of international adoptions. His children also continue this legacy of making a difference: His daughter, Elissa, is a special education teacher and co-authored the chapter on special education in this edition of Children with Disabilities; his son Michael is a social worker; and his younger son, Drew, has overcome the challenges of attention-deficit/hyperactivity disorder to graduate from Vassar College and enter business school.
