About

McAvoy & Markham Engineering and Sales Co was founded in 1981 by Frank McAvoy and Jim Markham to serve the electric power industry in Southern California. Since then we have expanded to cover Arizona and Nevada.

We are committed to providing the best value and support to our customers.

McAvoy-Markam has another wonderful side purpose, it supports the Nice Guys of San Diego. The Nice Guys have been a part of San Diego since 1979, helping local families and individuals who, through no fault of their own, have fallen on tough times. Our goal is to get people back on their feet and self-sufficient. – Join us!
