Meet the S&D Industrial Tool Supply Team

From what many have told us, S & D Industrial Tool Supply had humble beginnings. We got our start in 1984 out of the home of our founders Sam & Diane Martlaro. With only a handful of customers and a promise to "Provide Service and Dependability," they successfully broke into the competitive Southern California tool distribution market. Even though we have grown into one of Orange County's leading industrial tool suppliers, we are proud to say many of those original customers still partner with us for their tooling needs.

At S&D Tool Supply, we believe that excellent service and dependability begin with having the right team in place; a team of people with the right attitude, experience, and industry knowledge. Using this criteria, we have selectively grown our team over the years to meet these expectations.

Our inside Sales team all have 20 or more years experience serving our industry. Our outside Sales Team is regarded as the best technical application team in the area. Our team can take you from blueprint to finished products. With these things in mind, we are proud to introduce you to our entire team.
