OMB will continue to be managed locally by its current leaders and will adopt the Salas O’Brien name after a transition period, according to the company.

The acquisition brings in new clients in sectors like healthcare, hospitality, theme parks, research and manufacturing.

Salas O’Brien said it’s expected to bring in 2019 revenue of $145 million. The company is led by Darin Anderson, a 2019 Business Journal Excellence in Entrepreneurship honoree.
