Trench Shoring Company has expanded the diversity of its Trench Shoring University (TSU) with the addition of new trainer, Fred Estrada, and now provides bilingual classes in its training program.

Today, under the management of veteran North American Excavation Shoring Association (NAXSA)- certified t r a i n e r , G r e g Shreenan, Trench Shoring University can effectively communicate safety measures, dangers and risks of underground construction to the scores of workers for whom Spanish is their primary language.

The bilingual aspect of TSU can also be adapted for both online (remote learning) as well as classroom situations. Additionally, in the near future, Estrada will be offering Spanish-only training classes through Trench Shoring University.

Trainer Fred Estrada brings over forty years of experience in construction and shoring. From 1978- 81, He worked for CLPeck Construction, which built South Coast Plaza in Costa Mesa, CA. From 1981- 90, he worked for AEG Construction, a familyowned business, where he gained experience in identifying the right materials, equipment and tools for each project. Over the next 30 years, Fred worked for several companies including Rados Construction, where he gained experience in heavy civil engineering, pipe laying, construction of bridges and overpasses. He then moved on to FCI, the Silverado Eastern Transportation Corridor joint venture with Sukut, and then to Atkinson Construction, often working with the same core group of project workers, gaining valuable hands-on experience in every aspect of construction and trenching.

In 1998, Estrada was trained by Trench Shoring Company founder, Tom Malloy, in CAL-OSHAtrench and excavation standards and still proudly displays his Certificate of Completion from that training. He himself was motivated to enter the training profession so he could do his part to protect workers in the trenches. “Years ago, I saw three deaths firsthand in pipe laying,” he notes. “Back then, our teams weren’t properly trained because the current OSHA training just didn’t exist. There has been an evolution in hazard awareness over the past decade or so. I came to Trench Shoring Company with a determination to save lives.” 

His epiphany came during an early training, when several classmates asked Estrada to translate some of the information into Spanish. He realized even then that there was a huge need to communicate to these Spanish-speaking students who were reluctant to speak up.

Estrada received his formal classroom and computer training from TSU training manager, Greg Shreenan, who has almost two decades of classroom training. Like Estrada, Shreenan had over 30 years’ experience in construction. Two decades of ground experience with heavy equipment prepared him for his career in underground safety.

Certified as a National Utility Contractors Association (NUCA) instructor in 2006, Greg has trained over 10,000 people, is passionate about the potential of NAXSA to serve the training industry, and shares with Fred Estrada, a determination to keep people safe. Both Greg and Fred present TSU materials that are built from the latest in CPE and CSC curricula, and satisfy all OSHA requirements. This revamped training underscores Trench Shoring Company’s mission of safety in the trenches and the importance of superior training for its clients and contractors both throughout California, and Las Vegas, and now, throughout the country.
