Meet the S&D Industrial Tool Supply Team

In 1984, founders Sam & Diane Martlaro initiated operations from their home, armed with just a handful of clients and a commitment to "Provide Service and Dependability." Their venture proved successful, enabling them to establish a foothold in the fiercely competitive tool distribution market of Southern California. Despite evolving into one of Orange County's premier industrial tool suppliers, we take pride in maintaining enduring partnerships with many of our original customers.

At S&D Tool Supply, we firmly believe that outstanding service and reliability hinge on assembling the right team. Our team embodies the ideal combination of a positive attitude, extensive experience, and industry expertise. Guided by these principles, we have meticulously expanded our team over the years to meet and exceed these standards.

Our internal Sales team collectively boasts 20 or more years of experience dedicated to our industry. Recognized as the foremost technical application team in the region, our external Sales Team possesses the capability to guide you seamlessly from blueprint to finished products. With these considerations in mind, we are delighted to introduce you to our entire team.
