Doug Garriott

Doug Garriott started in the automotive business in 1980 working in a service station. He graduated from Lincoln Technical Institute here in Indianapolis, Indiana in 1984. Afterward, Doug worked in the field as a driveability technician for over six years. He later hired on as an instructor for Lincoln Technical Institute. He taught several classes including: Engine Performance, Fuel & Emissions Systems, Advanced Automotive Electronics, Service Shop Management and Service Shop Procedures. During this time, Doug also completed the “Master Instructor Train the Trainer Program”.

Doug came on board full time with Linder Technical Services in 1997 as the Injector “Wizard”. His main focus is in the injector lab. Doug spends countless hours on research and development each year. He works closely with Jim finding fixes for the “pattern failures”. On average, we ship around 250 injectors each week and that number is growing every day!

In addition to his responsibilities in the injector lab, Doug trains 1-2 groups of technicians each year here at our facility in Indianapolis.He also teaches fuel injection seminars at locations both at home and abroad and teaches the fuel injection portion of our one-week “Guru School.”

Doug also travels frequently with owner, Jim Linder, to trade shows across the country. They can regularly be seen in Columbus, OH, Ontario, CA, Lexington, KY and Kansas City, MO. The next time you are at an automotive trade show, look for the Linder Technical Services banner and stop by and say HI to the “Wizard”!
