Team USA Worlds

  • "Without a doubt the highlight of my shooting life has been qualifying and representing the United States as a member of Team USA in 2014"

  • Thanks to our beloved leader, Mike Voigt, we were able to win Gold in Open Senior.

  • In 2017 we again represented the USA in France at the World Championships, winning Silver.
    Sadly, Mike passed away this year, but I will always carry with me his words of calm determination. He was one of my biggest supporters, both publicly and behind the scenes with IPSC. 

  • If elected, I will truly have Mikes voice in my head, and gaze over my shoulder.

  • I am honored that Maggie Reese Voigt, Mikes' wife, fellow shooter and love of his life, has endorsed me to run for Area 2. (Thank you Maggie)

  • Mike, this is for you!


My Other Passion

  • I have been many places, and done many things.

  • I was raised on a ranch, introduced to the business world at age 17 as an auditor clerk, and founded and owned many startups.

  • I served in the military special forces, and could have made that my career but for a few decisions.

  • I have worked construction, photography, movies, law enforcement, security and accounting.

  • But I never lost my love for animals.

  • From horses, to dogs, to cats, to snakes and exotics.

  • Animals are never far from me, and I have devoted my life to helping them.

  • My dog school, which I founded in 1997, offers or has offered behavior modification, obedience, daycare, swimming, agility, boarding and AKC testing.

  • I have specialized in bomb detection, narcotic work, tracking, sports competition, French Ring, agility, protection dogs, dock diving and others.

  • I have trained dogs for movies, commercials and music videos. 

  • While my family comes first, it's always hard to decide if I love shooting or dogs more.

US Citizenship

  • In January 2017 I was sworn in as a United States citizen. This ended a long journey, and is one of the greatest moments in my life.

  • Words cannot express how it feels to give up everything, move to a strange country and start a new life. 

  • It was a difficult task, made more so by the cost. 

  • But I had a dogged determination to succeed. 

  • And I did it legally and by the book.

  • NO regrets! Ecstatic to be a part of a great country.

  • With me is my son Christopher, and my Dad, Leolin.

  • I have always been a competitor. I love the excitement, adrenaline and passion of going up against others. 

  • I have also competed in many dog sports, at local and national level.

  • Shown is French Judge Dominic Piton. Under him I earned the second highest score in history competing with my Belgian Malinois, Karnak.

  • In 2014 after competing in Dock Diving in California, I returned home, built my own commercial dock pool, bought the franchise and started our club. We went on to win the Facility of the Year in 2014.

  • I have also won titles in French Ring, Agility, Tracking, AKC Obedience, Detection and other dog sports.

  • I no longer compete in dog competition, preferring to focus my attention on the shooting sports.


Media Consultant

  • I worked for NBC for about ten years as a consultant on dog matters; appearing live, filming segments and occasionally producing short stories.

  • I have also appeared on Good Morning America discussing and demonstrating narcotic and explosive detection canines.

  • In the photo left, I filmed a segment with the chopper pilot of Channel 3 news.

  • I have also been involved in producing, and been interviewed by, projects related to shooting, guns and transportation of firearms.

  • No bio would be complete without some personal side of me. 

  • In this photo, I am hanging out with some guy in a fishing vest at the SHOT show in Las Vegas.

  • Seriously though, one of the things I enjoy about our sport is the friendships I have made with people from all over the world.

  • We don't always agree on everything - heck, I remember an argument I had with Rob over using electronic scoring. It was at Rio, and it went on for an hour.

  • But our sport brings us together

  • The best part of running for election has been making even more friends, and sharing the dream.
