Dr Tim Parker started teaching 30 years ago and hasn't stopped. He currently teaches dozens of courses a year, for many different audiences.

Timothy Parker Training Systems Inc. was created to provide a corporate framework for teaching and educational programs. Through Parker Training, thousands of courses have been delivered in a wide range of subjects to customers ranging from the US Military to Fortune 100 companies.

Parker Training is incorporated in several countries around the world and offers expert training programs, consulting services, and remote education programs to diverse audiences.

Ten years ago Dr Parker began converting his popular UNIX courses to video, allowing libraries and corporate customers to purchase the video courses for use. That trend continues with video training programs in a wide variety of subjects.

Dr Parker's latest venture is setting up a subsidiary in Vietnam, offering specialist training in a variety of fields.
