I completed level one training with David on 12/18/25 and this has been the best training I've ever received. Mr Brown is extremely knowledgeable, patient and does not beat around the bush with the dangers of this career. He has a passion for his work and wants to see men and women in the field be prepared. I scored 100% on my exam. I will be looking for future trainings at his establishment. God bless you, David Brown.

I’m 49 years old I’ve been going to the school for two years. This kung fu school saved my life. I was fat had heart issues and chronic pain. I was practically in a walker. I started out. It was very difficult but the stretching movement and memorization has changed my life. I am 25 pounds Lighter I have no pain and I’m moving around like never before. It’s good to learn a new skill when you’re older. Highly recommend

I'm a private investigator and manager at NarrowGate Security. We recently attended one of their Level-3 training courses which also included firearm certification. The classroom setting is very conducive to focused sessions and the curriculum is presented in a very clear, thorough and practical manner. Our instructor, David Brown has an incredibly firm grasp of the course material and his no-nonsense approach to teaching combined with his ability to connect with individuals of any skill level makes for an engaging and insightful experience. The entire Triad team is beaming with dedication and each of them has a deep commitment to situational awareness, respect and safety. Whether you're looking for a place to get a new certification requiring top-down training or a basic renewal, these inspired professionals are willing and able to bring out the best in you.

I highly recommend David Brown and his staff with Triad security services David is very knowledgeable, respectful and professional. I had to renew my level three guard card with class time and gun range time. My only regret was not taking or knowing of Mr. Brown’s service prior to my previous training 1,2 and 3 Otherwise I would have taken Mr. Brown classes from the beginning. It was an honor and privilege to have met such a wonderful man. The knowledge that Mr. Brown provides is stellar! If you are searching for great training for self improvement in defense for security purposes or individual knowledge. Look no further . Tony SFNM

I honestly loved this training and classes. It's the best I have been through in awhile. 20 years of security and D. Brown was great. Very knowledgeable and detailed and made sure we knew and understood what he was teaching. As a female security supervisor officer I can say I am more confident in myself and helping others . I would highly recommend him and his crew. They are dictated and determined to make sure we will be safe on our posts or jobs. I was never disappointed at all. I got my butt whipped and I am so grateful for it because I know how to properly defend myself and be safe. Best ever for security training. I won't go anywhere else.
