Professional Journey

Mohr joined UE Systems in 1988 as a salesman. The company was then about 15 years old. Michael F. Osterer had founded it in 1973 and was its president until 1985, and he remains chairman. UE Systems builds handheld and fixed ultrasound instruments, sold under the Ultraprobe name, along with acoustic cameras, remote monitoring systems and training. Maintenance teams use them to hear leaks, failing bearings and electrical discharge before they cause downtime.

Mohr moved up through the sales organization, first as regional sales manager and then as National Sales Manager, before becoming a vice president and eventually president. His career has run through the commercial side of the business, and Acorn Energy’s board describes his experience as operational and managerial, with a track record in product development and marketing leadership. Over his tenure UE Systems grew from a national brand into an international company. Its offices include Toronto, Mexico City, Hong Kong, India and Almelo in the Netherlands, and its customers include Fortune 500 companies.

In August 2018 Mohr joined Osterer on the board of Acorn Energy, Inc., whose executives also lead its OmniMetrix business. He sits on its Audit, Compensation and Nominating Committees, which the board has determined to be independent. He was nominated for re-election in the company’s August 2026 proxy statement. His reported beneficial holding in Acorn, about 3% of the common stock, includes shares held by UE Systems itself.
