As an already successful representative for Republic Conduit, Don Griffin was always looking for a new line to which he could apply his sales expertise. Don was immersed in the electrical industry and noticed a need for replacement lenses and lay-ins of all kinds. Diffuser Specialist was started in 1982 by Mary Ann and Don Griffin with the philosophy that it is always cheaper to replace the lens than replace the entire fixture. With very loyal customers, Diffuser Specialist quickly grew into South Texas’ primary source of diffusing materials and accessories.

The 90’s brought rapid growth as Diffuser Specialist expanded their product lines. As the business grew, Mary Ann found herself taking a larger role in the company and became CEO. Under her guidance, Diffuser Specialist branched out through the rest of Texas with a second location in Houston. This new location allowed for quicker shipping times to national and international customers. Our large warehouses and family owned hospitality make us the number one choice for all your plastic diffuser and electrical supply needs.
