After graduating from the University of Houston, Eric took a job as an electronic technician and installed and serviced life safety systems in high-rise buildings. After seven years he went to work for Dow Chemical as a power distribution engineer. His work with audio systems had made him very sensitive to grounding issues and he took this experience with him into power distribution. Because of this expertise, Eric became one of Dow’s grounding subject matter experts. This is also how Eric met Mike Holt, as Mike was looking for grounding experts for his 2002 Grounding vs. Bonding video.

Eric taught the National Electrical Code for professional engineering exam preparation for over 20 years, and has held continuing education teacher certificates for the states of Texas and New Mexico. He was on the electrical licensing and advisory board for the State of Texas, as well as on their electrician licensing exam board.
