Marsh Electronics

Representing the marketplace interests for over 30 years.

A closely held distributor of electronic componentry, Marsh Electronics is the kind of Wisconsin-based firm that the entire state can be proud of. A successful, mid-size employer, and a regional leader in distributing a wide range of electronic components and solutions throughout the North Central United States.

Although founded in 1937, O’Neil, Cannon, Hollman, DeJong & Laing came on board back in the 1980’s. In that time, the company was acquired by a larger National firm, then purchased back by the current management team. O’Neil was present at both transactions ensuring a smooth transition. Likewise, our firm has been involved in virtually every aspect of their business — from employment, contract, human resources, and more.

President John Casper has valued our relationship so much that our President, Jim DeJong, was asked to be a member of Marsh Electronics’ Board of Advisors.
