A native of Big Flats, NY, MAJ Colyer received his commission after attending the United States Military Academy at West Point in 2000.  He was selected to attend medical school directly after graduation and attended Penn State University.  It was at Penn State that he developed a strong interest in Ophthalmology and vision research.  Upon graduation from Penn State, he performed a transitional internship at Walter Reed Army Medical Center.  During residency, he cataloged every patient who sustained eye injuries from Operation Iraqi Freedom and Enduring Freedom as part of a IRB-approved research protocol.  This information has been used to brief Army leaders, the VA leadership, media, and Congress regarding the impact of vision loss on our wounded warriors.  Based principally on his interst in healing our wounded warriors, MAJ Colyer has over 30 publications to his credit.  He is an invited lecturer nationally and internationally.
