Avionics shop owners Ed Lansberg and Morris Brown

History of EDMO Distributors

In 1971, avionics shop owners Ed Lansberg and Morris Brown identified the need for a dependable avionics distributor in California. They agreed to form a partnership, and EDMO was born. The company soon became the distributor for the renowned manufacturer of avionics test equipment, IFR Systems (once Aeroflex, now part of VIAVI Solutions).

Over the next two decades, EDMO became an integral partner for avionics shops and avionics manufacturers throughout the United States and Canada. Wire, cable, and installation supplies were quickly added to the growing list of products and services offered.


The EDMO building

Growth in an Ever-Changing Industry

In 1993, EDMO moved its operation to Spokane, Washington, and within six years built its new headquarters where the business operates today. Since then, the company has grown to be a global supplier to the aviation industry with customers in more than 180 countries.

Always looking for a way to better serve the needs of its valued customers, EDMO opened a warehouse in Nashville, Tennessee in 2017. With this expansion, EDMO offers 1-2 day shipping to most of the US.

Looking to the Future

Today, EDMO still stands apart from the rest being recognized globally as a leading avionics distribution company. Customers have access to an extensive and readily available inventory while receiving exceptional and personalized service. EDMO’s marketing team brings significant value to all levels of manufacturers. The continued expansion of product lines and services guarantees that EDMO will meet the needs of the aviation industry today, and in the years ahead.
