Denver Colorado Criminal Defense Attorney Geoff DeWeese
A proud Colorado Native, Mr. DeWeese brings over 17 year of legal experience to the Law Firm of Jacob E. Martinez. Graduating from Fairview High School in Boulder, Geoff went on to earn his BA from Seattle Pacific University, and his JD from the University of Denver in 1999. Prior to starting law school, Geoff enlisted in the Army Reserves as a paralegal, soon becoming a sergeant, and upon graduating he was granted an Active Duty commission as an Army JAG attorney. Geoff is currently a lieutenant colonel in the Army Reserves.
During his time on Active Duty in the Army, Geoff held a wide array of challenging assignments. Early in his career he completed the Army’s challenging Airborne School and deployed to Kosovo. He served as a prosecutor in Germany, carrying the heaviest trial load in his Division and litigating complex cases including murder, rape, sexual assaults, possession of child pornography, and drug distribution conspiracies. In his practice, Geoff was noted for his meticulous trial preparation and his ability to work well with various law enforcement agencies.
Geoff next took on task of defending Soldiers as a trial defense counsel, spending four years in assignments in Alaska and Washington. A zealous advocate for his clients, Geoff’s success at suppressing evidence lead to law enforcement and commanders saying they had to “DeWeese proof” their cases. Geoff fought hard and earned key acquittals in tough sexual assault cases and got numerous cases dismissed prior to their even reaching trial.
His passion and skills lead to his being tapped to handle the toughest cases throughout the region to include California and Hawaii. In 2004 Geoff was assigned to be part of the defense team representing SPC Ryan Anderson, a member of the National Guard charged with aiding the enemy. Fighting against a government case that involved both Army Counterintelligence and FBI investigations and classified evidence, Geoff took the lead on key mental health issues.
Geoff was also responsible for the sentencing case, and helped his client avoid a life without parole sentence as argued for by the government. In other cases, Geoff became an expert in cybercrimes, obtained favorable pleas for clients charged with crimes such as accessory to murder, and represented a client in a retrial of a murder case nearly a decade old, helping his client move from a sentence to life without parole to a term of only thirty-five years.

In 2007 Geoff was sent to earn an advanced law degree, an LLM, in military law and focused a part of his research on sentencing in criminal cases. He was next assigned as the primary legal advisor to an Army Special Operations group, overseeing a junior prosecutor and providing legal advice for missions around the globe, and deploying for a short period to Qatar. He was next assigned as a chief of military justice for Army Central Command, overseeing prosecutors and cases in the United States, as well as in multiple countries across the middle east including Qatar, Kuwait, Iraq, Egypt, and Afghanistan, and deploying for a period of time to Kuwait.
In his final active duty assignment, Geoff was stationed for four years with the United States Strategic Command in Omaha, Nebraska, the senior military command responsible for nuclear, space, and cyberspace missions for the Department of Defense. In recognition of his background and talents, Geoff was made the chief of cyberspace operational law. Geoff provided critical advice on national security policy, future military planning, and current operations. He was invited to speak on cyber defense at prestigious NATO cyberspace conference in Tallinn, Estonia. Geoff still maintains a Top Secret, SCI clearance.
In 2015 Geoff put his family first and decided to settle back home in Colorado to allow his children to grow up without continuing moves and to be near grandparents. Being near the majestic Colorado Rockies was certainly a draw for the entire family. Geoff worked as a deputy district attorney in Arapahoe and Douglas counties from August 2015 through November 2016 when he joined Jacob E. Martinez and returned to the mission of zealously defending those charged with crimes. Upon leaving Active Duty, Geoff has continued his service as an Army Reserve officer and is currently a senior defense counsel.
Geoff has earned numerous awards and distinctions over the years including a Defense Meritorious Service Medal for saving the life of a climber on the highest mountain in the lower 48 states, California’s Mount Whitney. Geoff is a proud Airborne Paratrooper and has been designated with additional skill qualifications as an Expert in Military Justice and a member of the Army’s Cyber Mission Force.
A passionate advocate who listens and works with clients and helps them navigate the challenges of being charged with a crime, Geoff will work with you, always with the goal of achieving the best result possible and ensuring you can make informed decisions backed by a zealous defender who will protect your rights every step of the way. Geoff is a smart choice for you when facing criminal charges in state, federal, or military courts.
