Welcome Mcavoy & Markham
TSTM welcomes Mcavoy & Markham Engineering & Sales to our growing family of highly knowledgeable agents.

McAvoy & Markham was founded in 1981 by Frank McAvoy and Jim Markham to provide professional sales representation to the electric utilities. We are an agent and distributor for quality electrical supplies and components used for the measurement, construction and maintenance of the generation, transmission and distribution of electricity.

McAvoy & Markham offers a wide range of metering, distribution, substation and transmission, and tool product lines. We believe in selling only high quality items which are not necessarily the lowest costing products. We choose innovative suppliers that provide the best technology for our customers. We have many demonstration products available for customers to evaluate.
