Don and TC are very good people and carry themselves very professionally and friendly as well. Just did my renewal class for my CCL yesterday and it was a breeze. Don and TC also helped me out when I locked my keys in my car at the range that the class met at. I like how they tell the rules of the range and how things will go so we all have a sense of what was yet to come during the range and class times. They use the highest quality firearms for range day and highest quality range ammo. You will feel safe, secure, and confident, while and after attending your initial Concealed Carry or Renewal class while being guided by them. Thank y’all and will be continuing with TC and Don for every renewal for my CCL. They also offer other services too like detective training as well. Much appreciated y’all!!! More...

I was very satisfied with the results I had working with Don and TC. I came here to take the 20 hour unarmed security classes and to get assistance with applying for my PERC license. Don takes his teaching seriously and ensures that you are able to understand the importance of role and responsibilities you will be working in. TC is great and has a wealth of knowledge and experience. I would recommend you book your next classes with them. You will not be disappointed. More...

Armed Security
Our Armed Security Services provide a heightened level of protection for people, property, and assets where credible risk is present. Armed security officers are carefully selected, fully licensed, and trained in threat assessment, de-escalation, defensive tactics, and lawful use of force.
We focus on prevention first—maintaining a visible, professional presence that deters criminal activity while ensuring rapid, disciplined response when necessary. All services are delivered in strict compliance with state and federal laws, with clear use-of-force policies and ongoing training standards.
Armed security is appropriate for environments requiring an elevated security posture, including high-value assets, sensitive locations, or areas with increased risk.

Unarmed officers are trained in situational awareness, de-escalation, access control, and customer interaction, making them well-suited for environments where professionalism and communication are critical.
Officers work proactively to deter unwanted activity, enforce site policies, document incidents, and coordinate with management or law enforcement when necessary. All services are delivered in compliance with applicable laws, client directives, and established post orders.
Unarmed security is ideal for locations seeking effective security coverage without the need for armed personnel.
Missing Heirs
Our Missing Heirs Services assist attorneys, executors, fiduciaries, and courts in locating and identifying missing, unknown, or unresponsive heirs in probate and estate matters.

Each case is handled with discretion, accuracy, and respect for legal and ethical standards. Findings are documented in clear, court-ready reports designed to support probate proceedings, estate administration, and due-diligence requirements.
