NTT DATA acquired Keane in 2010. Perot Systems was established in Herndon, VA in 1988 by Ross Perot after selling EDS to GM. The Healthcare and Life Sciences business grew out of strong IT services relationships with companies such as Tenet Healthcare, Owens & Minor, and Harvard Pilgrim Health Care. Dell purchased Perot Systems in 2009 for $3.9 billion primarily for its Healthcare and Life Sciences vertical services expertise. Dell Services was purchased by NTT DATA Inc. in 2016, combining the strength of Keane and Dell Services to become NTT DATA Services.
