I always thought flying was the best part of my 20 years of Naval service. But when I really thought about it, I realized teaching and mentoring were by far the most rewarding aspects of my life as a Naval Officer. Once I retired in 2022 and finally got back to San Diego, I set to work finding the best way to continue mentoring future leaders.

I am excited and passionate about helping young people develop self-confidence in discovering who they are and what they want to be. As an instructor, I like to draw from my various experiences around the world and right here with my family in San Diego. My four kids continue to provide my wife and me with plenty of “learning opportunities.”

I love the outdoors and adventuring with my family.

I was born and raised in Milwaukee, Wisconsin, and proudly served in the U.S. Navy, enlisting on July 24, 2002. After dedicating 21 years of service, I retired as a Chief Petty Officer on August 31, 2023. Just a year later, I began living my dream as a Naval Science Instructor at Canyon Hills High School.

Throughout my military career, I discovered a deep passion for mentoring and guiding others. I believe high school is a pivotal time in a young person's life, and I am committed to helping them build a strong foundation of motivation and self-determination. My goal is to make a positive impact on as many students as I can.

Outside of work, I’m an avid runner and a coach for flag football, soccer, and basketball. I’m also a huge fan of horror, sci-fi, and comic books (anime not so much!). As a proud Cheesehead, I’m a die-hard Green Bay Packers fan and a shareholder (Go Pack Go!), and I love supporting the Milwaukee Bucks. Above all, I cherish spending quality time with my family. I’ve been happily married to my wife for 18 years, and together, we have three wonderful sons.
