Wm. Roger McPherson, Chairman of the Board
Roger McPherson founded Tengam in 1972 after developing and engineering a convergence ring magnet for the television industry. It was molded along with a part produced by McPherson Plastics, a family-run plastics business. Roger improved the manufacturing process and met the challenge of producing an industry first: injection molded magnets. This leading innovation had a strong impact in the marketplace and the magnet industry. Roger was quick to start developing better ways to produce parts using complex materials and innovative molding process techniques. With over 40 years of inventive ideas, Roger has continued to expand and improve upon his original manufacturing advancements, and has overseen Tengam’s steady growth. Roger is happily married, has two grown children and three grandchildren.

“Never mind what the past has delivered to you but do remember what it has taught you. So be passionate about your forward moving life, trust in your beliefs and in yourself, all while recognizing that you will never be able to do what your heart does not feel and what your mind did not imagine.”
Jeff Spitzner, Business Development Manager
Jeff joined the Tengam team in March of 2017 bringing with him an extensive range of knowledge. Jeff began his career in the United States Navy with a focus on operating and maintaining all the ships motor and generator sets. Following the Navy Jeff received a B.S. in Electrical Engineering from Western Michigan University. With degree in hand and experience in motors and generators Jeff worked in the magnet and motor winding business with responsibilities ranging from design, to quality, to product line manager. Jeff’s most recent employment gave him great experience in the heavy truck industry starting out as an engineer and eventually moving on to account management and sales and marketing. During this time Jeff earned his MBA in Global Management from the University of Phoenix.
Jeff and his family have a heart of serving their community through foster care. His family has taken in 11 children so far ranging from new born to 7 years old. Some of them only stay for a few days while others have been long term. One was made a permanent edition to their family when they adopted a 1 year old girl in November of 2016. That adoption had a significant impact on Jeff’s family showing them just a glimpse of the depth of love Jesus has for each person, thus providing the strong desire to continue serving the community.

Andrew Hirzel, Senior Engineer
Andy is deeply involved in magnet FEA design, test, manufacturing processing, quality control, and magnetization. Applications he has successfully undertaken have ranged from single particle magnetization analysis to 500 kW 1000 Hz synchronous motors. His theoretical understanding (Maxwell’s equations, anyone?) combined with practical factory experience provide a great fit to Tengam’s team. You will find that every subject related to magnetics is interesting to Andy, no matter the detail.
Andy graduated from the University of Michigan with a bachelor’s in Industrial & Operational Engineering: a background that, like most magnet people, was not specifically in the field. He has wide ranging experience in manufacturing, but after he drifted over to the domain of magnetics he has never quite broken free of that fundamental attractive force.
When not looking for magnet flux, Andy stays plenty busy with his wife and daughters. Andy is also prone to running nearly any distance, with any fellow runner. Stop by with your running shoes on, anytime.
