We often get asked "why is your name spelled wrong?" Trust us, we did pass 5th grade. There is some symbolism there. get a hold of us to schedule a class and find out what it means.

John "Jay" Jankovich

Jay began his career in 1997 when, after an ill advised trip to the Jackson Crossing mall, he found himself at USMC Recruit Training Depot, San Diego California. Jay was astonished to find his trip to California wasn’t the fun trip to the beach his recruiter had promised. Instead men in strange hats yelled at him for 13 weeks. Jay miraculously completed recruit training and infantry school, going on to serve fifteen years in the United States military as an Infantryman.

Jay visited twenty-four countries during his service, many of which were fun and relaxing. Some locations however… not so much. Jay deployed to Iraq, Afghanistan, and Djibouti - where Jay disliked the environment because the military banned alcohol consumption there. Jay eventually advanced to a rank where he no longer did cool, action-guy stuff, and was promoted to making power point slides for commissioned officers. His service ended in late 2012 after a comedy of errors in Iraq led to an eventual medical retirement. He’s been training any law abiding citizen he can get his hands on ever since.

Jay has been a firearms instructor since 2000, with instructor level courses including USMC Rifle/Pistol Coach, USMC MOUT Instructor Course, US Army Small Arms Master Gunner’s Course, CSAT Rifle/Pistol Instructor Course, NRA and USCCA CPL Instructor courses, and numerous other courses that serve only to inflate his already massive ego. At one point Jay somehow got a college degree in criminal justice, defying the predictions of Mrs. Walker, his fifth grade teacher, who once told him he'd be lucky to graduate the fifth grade.

Jay has worked as an infantryman, a small unit leader, a court officer, armed security, body guard, bar bouncer, professional shooting instructor and coach, and he even survived holding the flashlight for his dad in the 1980s when the car needed fixing.

Jay loves teaching because he passionately believes citizens can make a difference against the forces of evil if only someone would show them how. Preferably for money, though to his wife's chagrin, he often gives away knowledge totally for free. Whether this is out of concern for great Americans or just to hear the sound of his voice, is a matter of intense debate.

    I have been training with MCD since 2018, I have taken each individual module they offer and most of the team ones and I keep coming back. The reason is simple, it is effective, progressive, structured training that starts and ends with a complete mastery of fundamentals. From the ground up each class was designed to reinforce the fundamentals and build off of each other, you will be in CQB and it will click, wait, that's why he's been having me do it this way. Jay makes it fun when it needs to be and serious when it's game time. You will get your moneys worth, that I can promise you.
    I appreciated the classes because each drill built on the following drill and the instructors ability to quickly and professionally troubleshoot and assess each individual student in regards to what they are doing and helping each student reach their potential in achieving clean shot groups and executing shots on the desired target.
    Looking for years,

    I have taken courses before and most of them miss the mark on instruction that I can understand and apply. Jay and his team work efficiently and use common sense to get the basics across. After learning from Jay and his team I feel more confident in my ability to defend myself and those I love and care about.
    At this point I've taken all of the pistol classes and followed them with the basic rifle and Rifle CQM. I couldn't be happier with the time and effort I've spent with instructor Jankovich. I'd recommend any one of his classes.
