About
Throughout my 23-year career in Force Reconnaissance, special missions support, and national-level contracting roles, I’ve learned that mission success is built on disciplined execution, trust, and strong leadership. I’ve led Marines and joint-service personnel in complex, high-pressure environments where precision, adaptability, and teamwork are non-negotiable.Across my career, I’ve planned, coordinated, and executed sensitive operations supporting national security objectives; managed high-risk dive and reconnaissance training programs; and integrated emerging technologies across tactical and operational environments. Whether leading a Force Reconnaissance Team in combat, or supporting international and interagency defense efforts, I’ve built a reputation for calm decision making, integrity, and mission-focused leadership.Where I am headed:I am continuing to expand my impact in the defense, intelligence, and special operations support community. I’m focused on roles that leverage my background in project management, tactical operations, technical surveillance, and team leadership. I bring a steady hand, a strategic mindset, and more than two decades of experience working at the intersection of risk, readiness, and national-level mission support.Let’s connect if: • You are a defense or intelligence organization seeking a trusted leader with deep operational experience and a proven track record in complex environments. • You are a program manager or contracting lead looking for a strategic problem solver who can integrate training, technology, and personnel into high-performance teams. • You are a professional who values conversations around leadership, innovation, technology integration, and service.

Experience

Senior Enlisted Advisor / Operations Chief
Served in roles of increasing responsibility to include Force Reconnaissance Team Leader, Chief Instructor for the Marine Corps Combatant Dive Detachment, and Operations Chief for a 135-person Force Recon Company. Across these assignments, I led complex training and operational programs, mentored elite personnel, integrated advanced technologies, and supported mission-critical operations across joint-service and interagency environments. I directed long-range reconnaissance, urban surveillance, precision fires integration, and military freefall and dive operations during multiple deployments, leading teams in dynamic and high-pressure environments. As Chief Instructor for the Marine Corps Combatant Dive Detachment, I managed all aspects of specialized dive training and oversaw the qualification of more than 200 divers across the Marine Corps, Navy, and AFSOC. In this role, I shaped curriculum, enforced stringent safety standards, and advised senior leadership on modernization and capability development for future dive operations. As Operations Chief for 3rd Force Reconnaissance Company, I oversaw operational readiness, training plans, and deployment preparation for a Force Recon unit consisting of 60 Reconnaissance Marines and more than 135 total personnel. I served as the senior enlisted advisor to the Commanding Officer, guiding organizational priorities, risk management, and resource allocation to maintain a high-performing operational culture. This body of work reflects more than two decades of leadership, operational excellence, and technical proficiency, built in some of the most demanding environments in the U.S. Armed Forces.
