Our Founder

John Tarr Sr. began his career in 1967 with Fisher Scientific (ThermoFisher Scientific), in the QC Department for Instrument Manufacturing.  

Over the next 10 years, John held several engineering and technical training positions.  In 1978, after ensuring the manufacturing team "got the process right", John joined the Technical Service Group for Instrument Repair as a Senior Service Specialist for the Atlanta district.

A mere 3 years later in 1981, John was promoted as the District Service Manager for Detroit and Cleveland. In 1987, after a 20-year career with Fisher Scientific, the foundation was rock solid for John to go off on his own.

As one of the most experienced and knowledgeable field technicians for laboratory equipment in the United States and a passion for helping people who help people, John founded Service Specialist of America, Inc. with the support of his loving wife, Joyce.

Now semi-retired, John acts as a consultant to our company by leading training seminars and imparting decades of knowledge on the SSoA staff.  Every now and then John will make a service call and connect with customers that became his friends over the past 30 years.

The Core Values John and Joyce founded SSoA upon remain today and are the basis on which we run our business:

  • Be Honest
  • Be Helpful
  • Be Creative
  • Be Thorough
