While we had already been providing training services for several years, Shafer Environmental (now Trailmarker Ltd) formally established its training division, Ground Zero Instruction (GZI) in 1990. This photograph was published in The Meadville Tribune along with a story in February 1990. Dave Shafer is still conducting training courses under Trailmarker GZI.
Besides Bill and Ray, several other highly qualified instructors have been integral to the quality and effectiveness of our training including Larry Bonino, Dave Kummerlowe, Ron Weikal, and Karen Eglinton. We are proud of our efforts and are appreciative of those that have worked and supported GZI through the years.
Still pushing “The Practical Approach” GZI offers a full range of hands-on and classroom training including HAZWOPER, permit-required confined space entry, hazard communication and GHS, respiratory protection and air monitoring instrument use. Contact Dave Shafer for more information.
