Currently serving on active duty in the U.S. Navy as an Operations Specialist with a specialty in ASTAC (Anti-Surface/Subsurface Tactical Air Controller), I’ve developed strong skills in high-pressure decision-making, strategic coordination, and operational efficiency. Now pursuing a Bachelor of Science in Accounting from UMGC, I’m transitioning that same precision and analytical mindset into the world of finance and business management. My goal is to bring a disciplined, detail-oriented approach to helping businesses manage and optimize their finances.
Outside of crunching numbers, I enjoy working on cars, tackling hands-on projects, and spending time outdoors—whether it’s hiking, working out, or simply enjoying nature. I’ve been happily married to my wife Sofia for two years, and life is always exciting with our two dogs, Ichigo and Ollie. After spending three years living in Japan, I’ve gained a deep appreciation for global cultures and look forward to continuing to travel and explore the world.
