The Estrin Zirkman Sales Agency was founded by Michael Estrin June 1993. (Originally called Estrin Sales Agency) 1993 was a very different world, but the fundamentals of business always have remained the same. Service. Service to the Designer, Service to the Dealer, Service to the Contractor, Service to the manufacturer. By giving the highest quality service, people naturally gravitate to the products we represent. We always do our very best to satisfy everyone. Repeat business is the most important. We pride ourselves on being versatile. We fit our talents to the need. We are honest and direct in our communications. We truly enjoy what we do and who we do it for!!!
