Jack Rumbaugh, Suarez International's new Director of Training, has been the Tier One Staff Instructor for the states of Virginia, West Virginia, and Maryland since his moving to the area in 2004. Jack is one of SI's original staff instructors. He teaches out of his home range outside of Winchester, VA and travels all along the Mid-Atlantic as well as nation-wide to present the Suarez International family of classes. Jack found Suarez International in 2002 and the material presented resonated with him. He wanted to be a part of spreading the common-sense approach to gunfighting and became an instructor in short order.

Jack is a former column editor for Concealed Carry Magazine and still contributes on occasion. His column, The Force on Force Notebook, gained national exposure when his study of the Virginia Tech shootings was featured in a panel discussion hosted by the Southern Sociological Society in Richmond, VA in 2008.

Jack is certified to teach nearly all of the Suarez International curriculum, including Close Range Gunfighting, Extreme Close Range Gunfighting, 0-5 Feet Gunfighting, Defensive Knife, Terrorist and Active Shooter Interdiction, HRO CQB-Fighting in Houses, Force On Force Gunfighting, and Kalashnikov Rifle Gunfighting, just to name a few.

Originally from Florida, Jack has been around guns most of his life, learning to shoot before he entered the first grade. His introduction to Martial Arts began in Middle School and he has retained an interest to this day. Jack is an avid student of the knife since he hosted a knife seminar in 2006. Jack believes that anyone who carries a gun should also pursue some of the other martial disciplines to be a well-rounded fighter. He lives in the distant suburbs of Washington, DC with his family and his two dogs.
