Next to Disneyland, few companies have as rich a history of innovation and longevity in Anaheim as Mettler Electronics. Founded in 1957 by engineer and inventor, Hal Mettler, the firm is the world leader in portable ultrasound and electro-stimulation therapy equipment used in chiropractic, physical therapy and sports medicine.Hal's son Stephen C. Mettler was, until recently, the firm's President and Chief Operating Officer. Today his son, Mark Mettler, serves as President and heads up International Sales. Matt Mettler serves as Vice President and National Sales Manager.Hal Mettler introduced his company and groundbreaking Sonicator 700 in June of 1957, with its unheard of price of $199.50. Because the new device was so affordable and portable, it revolutionized ultrasound therapy, making it readily available to a wide range of therapists and patients. With the new Sonicator, therapists could move the machine easily between treatment settings to reach any patient requiring therapy. It was an engineering breakthrough on the order of the transistor radio.
