About Us

John Ryburn Services (JRS) was established by John Ryburn in 1987 in Noel, Missouri.
JRS was incorporated as John Ryburn Services, Inc. in 1994. The founder, John Ryburn, has over 30 years of experience on Thermco equipment and over 46 years of experience in electronics. Since its establishment, JRS has maintained an excellent growth rate dedicated to providing quality service for Thermco, ASM PECVD and virtually any other type of diffusion furnace.

People ask how we ended up in this small town in rural Missouri. After retiring as a Vice-President from Thermco Systems, Inc., John Ryburn started consulting due to customer demand. He was also frequently requested to supply training on Thermco TMX equipment. A site was needed close to home for this purpose and it had to be a location that could support this type of equipment. The JRS location in Lanagan has worked out very well as a training facility for many years.

JRS supplies extensive training, equipment support and service, specially engineered products, and circuit board repair to all customers. Additional capabilities include process engineering support and upgrades to Thermco TMX Systems, ASM Plasma Systems and Semy Mypro.

JRS draws from a varied group of experienced specialists throughout the United States with numerous combined years of experience on diffusion and plasma furnaces and various other equipment. Each of these specialists is willing to travel world-wide to provide service to our customers.

Thanks to the many satisfied customers we provide service to, JRS continues to grow. If an item of particular need for your organization is not mentioned above, please don't hesitate to contact us.
