Dermot O’Reilly was appointed on September 16, 2016, to be the acting Director of the Defense Criminal Investigative Service (DCIS).

He then went to work for the Air Force’s Office of Special Investigations’ (OSI) Boston office as a criminal investigator. While there, he went to Harvard, earning an M.A. in government in 1998. In 2001, he was sent to London as OSI’s resident agent in charge. He returned to the U.S. in 2004 as chief of the inspections division.


O’Reilly in 2006 was made director of operations for OSI’s Region 7. Later that year, he became acting special agent in charge of OSI’s Office of Special Projects. In 2009, he moved over to the National Reconnaissance Office as deputy director of the Office of Security and Counterintelligence, a joint-duty assignment. He took a year off to attend the National War College and, upon earning a master’s degree in national security strategies in 2012, returned to OSI as Deputy Executive Director. While in that post, he served for a few months in the Joint Counterintelligence Unit in Kabul, Afghanistan. In 2014, he was made the Defense Department’s Assistant Inspector General for Investigations, with responsibility for international operations, national security and cyber security. He held that post until taking over at DCIS.

Please open an investigation like the navy one involving the Orlando VA padding the Rx drugs sold thru the pharmacy and do not limit this to just Orlando it appears to be a common practice to Rx lots of vets and not provide the co pay waivers as the co pay waiver for Rx is a seperate form in addition to the co pay waiver for services, i specifically told my Drs I wanted walgreens Rx and repeaatedly that was ignored by the VA I refused the last Rx and demanded my treating order the Rx at Walgreens and the cost was about 2.00 VA wanted 24.00 more than what BCBS paid them. I also had failure to comply with patient choice skin cancer treatment after the first few months the VA stopped paying and I had a bill over 1000.00 The VA still screwed up the billing process with BCBS which passes the bill to the Veteran. I request that you look into this as well nothing fits you as a patient cannot book a van ride at the time and location of the scheduling which results in missed appointments and Drs without patients in a work day. Over one million were missed as I recall.The VA failed to send notice on time of appointments and failed to even update the appointment cards which would arrive after the appointment was missed.
