About Us

Midwest Time Control was established in 1988 to supply the time equipment industry with reliable master clock systems. We offer a full line of Master and secondary clocks as well as power boosters and power supplies. Our Master Clock line is compatible with most clock systems on the market and with many older clock systems, as are our versatile digital and analog clocks.

Your timekeeping expert, Dennis and the good woman behind him, Jackie.

In 2013, husband and wife team Dennis Sundermeyer and Jackie St Aubyn purchased MTC from its founder Mike Moon.  Educated as an electronics technician in the US Navy and at the University of Missouri, Dennis has spent his career in electronics with a focus on radar systems.  Jackie’s expertise is in office management and customer service.   Originally located in Owasso, Oklahoma, we have migrated south over the years.   Now (and forever) located in the Rio Grande Valley on the Texas/Mexico border, you’ll find us in the town of Donna, Texas, just 45 minutes west of Brownsville.

Our dealers are our lifeline.  We strive to keep current on new technologies and product enhancements based on the feedback of installers and end users.  While Midwest Time Control is small enough to respond quickly, we are large enough to supply the volume of equipment you need.

Our products have a proven record of reliability. New products are extensively tested to live up to or exceed the standards expected by the industry. The Master Clock, which is the heart of any clock system, is unequaled in reliability and serviceability.  Let us help you solve your timekeeping issues.
