Very efficient professional staff well-trained. Located on POST Road Westbury. Convenient if you live in Nassau Suffolk or even it's not that far from QUEENS. Checked their website or call them if you need specific training. Saturday classes are available.

School was fantastic. Bernard is very knowledgeable and you will walk out of this school with a new perspective on security. You are not just getting your license in this school, you are going to learn valuable knowledge that will help you on the job. There is no doubt in my mind this is the best security school around period.

Recently took my eight hour course here and was very impressed by the professionalism and care shown by Interstate Security & Investigations. They cover all bases, have time, have patience for you, and not only help you to get your license but help you to find employment as well. Bernard Hardy and his team are professionals and I intend to go back to them indefinitely.

Through Mr. Hardy and his team at Interstate I completed my 8-hour pre-assignment training and 16-hour on-the-job training. Each course was presented in a fun and relaxed format. In addition to preparing you for a role in securities, Mr. Hardy adds insight from his experience to motivate you towards being a successful person. Everyone was professional and delightful, prompt and courteous. Highly recommended.
