Profile Information

Short Bio:
I'm an analytical, details-oriented, results-driven Operations Research Analyst, Logistician and proven leader. Known for process improvement, applying operational research/systems engineering techniques to answer complex questions faced by Headquarters Marine Corps decision makers.

I'm truly passionate about improvement and using operations research/data science methods to influence beneficial change when required, but there are times when simple works and I understand that balance.

I have experience with predictive analytics, queuing models, discrete-event simulation software, optimization modeling, applied statistics, relational databases and data visualization methods.

I'm also a firm believer that hardly ever is there significant impact without effective team involvement. I offer exceptional team and interpersonal skills coupled, with strong communication and presentation skills.

I have over 17 years of proven leadership, 7 years as a Marine Corps Logistics Officer and over 1 year of Operations Research experience for Headquarters Marine Corps at the Pentagon.
