DENVER — EKS&H, a Denver-based accounting firm with operations in Fort Collins and Boulder, has completed a merger with Detroit-based Plante Moran.

The combined company is now the 11th largest accounting, tax, consulting and wealth management firm in the nation.

EKS&H has offices at 1155 Canyon Blvd. in Boulder and 1321 Oakridge Drive in Fort Collins. Each office has roughly 40 employees.

The firm, founded in 1978, also has two offices in Denver and one in San Francisco and employs a total of roughly 750 people company-wide.

Plante Moran has about 2,300 employees in offices in Michigan, Illinois, Ohio, Japan, India and Mexico.

In 2017, the two companies had combined revenues of $626 million.

To celebrate the merger, Plante Moran is hosting a charity contest called Plante Moran Cares. The contest will award $30,000 to three Colorado non-profit organizations.

“The fact that we’re a larger and stronger firm only strengthens our commitment to our staff and our community,” Joe Bertsch, managing partner of Plante Moran’s Rocky Mountain region, said in a prepared statement. “We couldn’t think of a better way to celebrate the combination of our two firms than by giving back to a community that’s given much to us throughout the years.”

Nominations will be accepted through Oct. 11. For more information and to register, visit plantemoran.com/cares.
