The Murrieta Chamber of Commerce has been using National Business Investigations for years and there is a reason why. It's because they are the best! We help to run a three day Irish Music Festival in our City and always trust this company with all of our security needs. Their staff is fully in charge of making sure our event runs smoothly for all staff, volunteers and the public. The attendance this year was 8,000 people and not one problem. They are professional and friendly-always! But can flex the muscle if ever needed. We highly recommend National Business Investigations! Rhonda Warner VP Operations Murrieta Chamber of Commerce
