About e3 Diagnostics St. Louis

e3 Diagnostics St. Louis opened in 1988 as GNS Audiometrics, Inc. As one of our two founding employees, Dave Stewart started as a Service Manager and eventually took on the role of Regional Sales Manager in 1996. As one of his first orders of business, he hired current technician Jay Feco to head up the service department.

Eventually, our name changed from GNS Audiometrics, Inc. to Gordon Stowe, but our vision and dedication to customer service remained unchanged. We’ve even added more technicians to increase the output of our service department, and an Office Assistant to improve our administrative and customer service processes.

Each member of our St. Louis area team of professionals has extensive backgrounds in the following service areas:

  • Electronics Engineering
  • Telecommunications
  • Field Service
  • Medical Equipment Calibration and Repair
  • Hearing Healthcare Product Service and Repair
  • PC Networking
  • Sound Booth Assembly

We strive to provide our customers with a more service-based and consultative approach. This means we put emphasis around helping you understand your audiology equipment options so you can make good decisions based on your facility needs and budget. Our factory trained technicians also work with your to ensure your audiological instruments are calibrated and working properly on a daily basis.

In need of a new audiometer, tympanometer, OAE screener, or hearing instrument fitting system? How about repair or calibration services on your current instruments? Get in touch with us today! We’d love to chat with you and guide you through our expansive product catalog to find the perfect device for you!
