After serving as CACI's President and Chief Executive Officer for 23 years, Dr. London stepped out of the CEO role to become Executive Chairman on July 1, 2007. In this position, he oversees strategic initiatives to ensure shareholder value, advance client missions, cultivate key client relationships, and monitor major financial transactions, including CACI's legacy mergers and acquisitions (M&A) program that Dr. London began in 1992. He has an established role as a public figure representing CACI to customers and the federal information technology (IT) industry. Dr. London's efforts also focus on the evolution and transformation of defense, intelligence, information technology, and network communications. Dr. London has written and published Our Good Name (Washington, DC: Regnery, 2008), documenting CACI's remarkable campaign to challenge the grossly distorted and exaggerated media reporting of the company's work in Iraq for the U.S. Army at AbuGhraib prison. Drawing from official government documents, sworn public testimony, and public records, Our Good Name sets the record straight and details how CACI succeeded in overcoming false allegations while meeting the urgent needs of a nation at war. He is also the author of the book, Character: the Ultimate Success Factor (Jacksonville: Adducent, 2013), which provides an insightful and practical demonstration of how good character and ethics are the key to long-term success for both organizations and individuals. Dr. London is regularly invited to speak about character and ethics in the media and at public forums, and in August 2014 instructed a webinar on the influence of character as part of a certificate program offered to senior leaders in the federal community by the online university TMGovU.
