Mark B. Carlson

Founder & Vice Present

Mark founded Martel on July 2, 1984 because he recognized the need for a reputable firm to provide telecommunications solutions for businesses on Delmarva. He brought with him an extensive background in technology and electronics repair, but most important was his dedication and desire to build a better future with his business. In a true example of the “American Dream,” Mark has grown Martel from one man working out of a garage to a full-service technology solutions company with a wide range of products and services and a full staff of technicians and sales team operating from a commercial facility in Dover, DE with a fully stocked parts warehouse and 24/7 service.

With over 45 years of experience in the technology and construction fields, Mark remains a tremendous technical resource for the company and looks forward to many more years of helping clients succeed. In his free time, Mark enjoys spending time with family and boating on the many waterways on Delmarva.
