"The course was very useful for me. The instructors are very knowledgeable and take interest in helping out individuals in their specific work-related problems."
—Arvind Sethuraman, Mesa Natural Gas Solutions, Power Systems Engineer
"Your use of Zoom (web interface) was the best I've been part of! I've been in other web-based training sessions in the past 12-18 months and you by far have it down! I really enjoyed that you took the time for specific questions! Great training!"
—Joel LeMahieu, DeTroye Electric Services, Inc., Electrical Department Manager
"This training made me confident in what I felt I already knew and gave me an understanding of the areas that were not clear in the NEC."
—Richard Linke, Hilscher-Clarke Electrical Contractors and Engineers, Electrical Designer
"Instructor was extremely knowledgeable on the subject with many real-life examples."
—Glenn Walls, Professional Power Systems, Owner
