John Cadwell, BSEE, MD, develops the world’s first microprocessor EMG in the basement of his Seattle home during his residency at the University of Washington School of Medicine. He partners with his brother, Carl Cadwell, DDS, to form Cadwell Laboratories. Their first product is the Cadwell 7000 EMG.
The Cadwell 5200A puts Cadwell on the map. This small, powerful, robust and easy to use machine becomes the best-selling EMG machine ever made. The company outgrows its previous facility and moves into 909 N. Kellogg St. in 1986.
Responding to changes in industry trends, Cadwell replaces the 5200A with the Sierra line, which continues to serve the global EMG market today.
