"Came here to take my TRAQ Certification through the ISA. They did really well in taking protective measures for COVID19. They spaced us out properly, good air flow, good presentation setup for the instructor/proctor, and the grounds themselves was very pleasant. Good place to test. The trees on the grounds were a great example to test on for risk assessments. Overall a great experience, and recommend as a place for extended learning development."
