My name is Hector Vivieca, and I bring more than 20 years of combined military and law enforcement experience to every class. I currently serve as a Federal Law Enforcement Supervisor and previously served as a police officer with the Metropolitan Police Department in Washington, D.C.
I am also a U.S. Army veteran and have completed advanced tactical and firearms training, including SWAT-related instruction. My goal is simple: provide professional firearms training that helps responsible citizens become safer, more knowledgeable, and more confident firearm owners.
