Professional Safety Training Services (PSTS), Inc. is a minority-owned and family business founded in 1988 By Calvin C. Williams, Sr. while employed as the Regional Health, Safety and Environmental Compliance Director for a large Chemical Waste Management firm. His son, C. Curtis Williams, II worked in the HAZWOPER field in 1990. Then, went into the Army as an Airborne Medic. In 1996, he joined the company as an instructor and now owns and operates the company. Our PSTS company logo represents a person extending their hand downward to pull the other person upward, across the threshold to safety. Our slogan is: “Place the Safety of your Employees in Our Hands!” The slogan coincides with the helping hand depicted in the logo. We gladly extend out our hands to be of service to you and your company. Our mission is to make sure that everyone we teach know that they are responsible for their own safety and well being and that safety is not optional.
