Owner and Lead Instructor - Beau Doboszenski

Beau joined Defensive Mindset Training’s predecessor, Sealed Mindset Training, in 2010. He took on every role as he dove into the defense training industry, and developed his expertise as lead instructor, manager, videographer, photographer, scriptwriter, editor, and curriculum developer.

Beau took over and rebranded Defensive Mindset Training in 2017 to continue training and content development. He is passionate about giving people the confidence of knowing they can protect themselves and their loved ones, or the ability to rout their opponents at firearms competitions. His experience is that firearms should be practiced like any other martial art, where it’s regular training over time that leads to mastery.

Beau loves teaching all skill levels, whether reducing a novice’s stress at handling their first firearm or helping elite shooters hone their technique to improve speed or accuracy. He focuses on physics, neuroscience, and proven effectiveness — not just how cool something looks on camera. In his own training time, Beau lives for an excellent range session with lightning fast draws and split times and perfect accuracy with his rounds.

Beau’s background includes:

  • 4 years as a US Army Parachute Infantryman, including acting as a first responder in the Pentagon on 9/11

  • 2 years as a Sentinel and Relief Commander at the Tomb of the Unknown Soldier in Arlington National Cemetery

  • Black belts in 5 martial arts, plus years of experience in many others

  • A degree in history, with a focus on military history

When he’s not working, Beau enjoys cooking, listening to podcasts, and spending time with his wife, sons, and two dogs. 

A private training session with Beau gives you exclusive access to the guy behind the entire DMT program, who can help with any issue and answer any question.


Instructor - Kevin

In 2017 Kevin arrived to take DMT’s Foundation Handgun / Rifle classes and knew he’d found his home. In 2018, Kevin became one of Beau’s Advanced students and a training assistant before eventually becoming an instructor himself. He lives for teaching and helping others develop their very own warrior spirit and defensive mindset.

Kevin’s background includes:

  • Current Law Enforcement Officer

  • 3+ years in the Army as a Parachute Infantryman

  • 10+ years of Martial Arts and Self Defense training. Currently training in BJJ and Muay Thai Kickboxing

When he is not working, Kevin is constantly training in the gym, studying Psychology, researching new material, and finding ways to improve the training curriculum or dry fire training at home with his SIRT Pistols.

A private training session with Kevin lets you work with one of DMT’s most experienced instructors, who’s also a current Law Enforcement Officer. Kevin’s the resident expert in gun gear and equipment, and can help you develop your ideal setup.


Instructor - Blake

Blake spent many years in the Martial arts followed by an amateur career in full contact fighting in Illinois. During this time, Blake looked into joining Law Enforcement to protect and serve, which is when he became interested in firearms and training.

When a different career path eventually brought Blake to Minnesota to train with a local pro full-contact fighter, Blake discovered Sealed Mindset Training (now Defensive Mindset Training) in 2011 and began to train and craft his firearms skills using their proven training method.

With the recent civil uprising in Minneapolis, Blake realized that DMT has been the leading training company to help citizen defenders. He joined DMT as an instructor to help fill the needs of new gun owners looking to protect themselves. 

Blake trains regularly in combatives with firearms, and has spent time with local Law Enforcement departments in scenarios, force on force, and peace officer training. He has experience in American and Muay Thai Kickboxing as well as Kali.

A private training session with Blake brings you expert instruction, along with Blake’s mastery of the physical aspect of gun defense and ability to help you connect combatives with firearms.


INSTRUCTOR - JORDAN

Jordan began training with Defensive Mindset Training in 2017, eventually becoming an instructor. He has a strong passion for teaching self-defense and firearms and building confidence in fellow citizen defenders. Jordan’s degree in education taught him how to engage with students to make sure they’re actually learning, step-by-step. He has spent thousands of hours training and teaching firearms, from foundational levels to advanced tactics and scenarios. Jordan regularly wins Top Shot at national firearms training academies, which he credits to the superior instruction at DMT.
