I was Aaron's divisional Chief while serving onboard the nuclear submarine USS Kentucky (SSBN 737) (Blue) when he first reported. The time I spent with him, I found him to be a very intelligent and a driven sailor. He adapted very well to his new surroundings with a great attitude. He quickly grasped the inner workings of a complex communications suite which involved many modems, sensitive cryptograph equipment, and computer based programs for configuring circuits needed to ensure national security in the short time I was his supervisor. For any position Aaron is applying for, you will get a very good and knowledgeable asset as well as a supportive team member. - John Manogue | Ship Superintendent | Portsmouth Naval Shipyard
