Goldsmith Security Academy, Bartlett

The head honcho of Goldsmith Security Academy doesn't mess around—in addition to being a civil-service bada$* who acts as a public notary, warrant giver, and subpoena server, he's an expert in firearms, security, and tactical defense. And he passes on his accumulated wisdom at his academy, where he teaches classes on security—both armed and unarmed—and proper handgun ownership. In fact, he oversees courses sanctioned by the state of Tennessee for prospective gun owners to acquire the necessary handgun permits.
