Galveston County Daily News, July 14, 2008 Melvin Williams, director of the office of equal opportunity and diversity at UTMB, writes in this guest column about the 18th anniversary of the Americans with Disabilities Act, which was signed into law by President George H. W. Bush in July 1990. UTMB will recognize the signing of the ADA at noon on Tuesday in Levin Hall, with a celebration that will feature Jonathan Kaufman, president and founder of DisabilityWorks. "More and more organizations will begin to view workers with disabilities as assets and once they do, they will come to realize how much diversity exists within the disabled community."
