More Info on Lieder Development

Lieder Development began in 1968 by founder Gordon J. Leslie. Gordon began his executive career as Manufacturing Head of Research and Development at Rover Cars in England. He was responsible for design and production of the first 35 Rover vehicles with gas turbine engines.

After immigrating to the United States, Leslie began his career in the waveguide industry as a V.P. with A.T. Wall. He founded Lieder Development in 1968 and by 1977 the organization was incorporated in the state of California. Leslie’s goal was to provide the highest quality passive waveguide components with the best delivery time in the industry.

Since then, Lieder Development has been known throughout the world as a company where quality, service, delivery time and competitive cost are always mission critical to our customer’s success. We’ve built our reputation on providing the best quality and delivery time in the industry. Lieder has received numerous quality awards over the years, including Northrop Grumman's Space Technology Gold Supplier award.

Our current executive team of five individuals has over 100 years of combined experience and technological expertise in the waveguide industry. Lieder is equipped and ready with the solutions our customers need in the time they need them.
