Wright Medical plans to add 100 employees to its Cherry Road corporate headquarters.

The 100 employees, which would bring Wright’s workforce at the location to 400, would be part of a 20,000-square-foot expansion of the headquarters, according to an application to the city-county Office of Planning and Development for additional parking.

The application was filed March 26 by the Pickering Firm Inc., which would design the parking plan for RBM Cherry Road Partners, the company that owns the property and leases it to Wright.

Wright moved from Arlington to the Cherry Road campus in January 2014.

“With Wright’s continued growth and the recent announcement of their merger with Netherlands-based Tornier, Wright would now like to expand into the remaining 20k square feet to accommodate an additional 100 employees,” wrote Cara L. Martin, principal owner of Pickering Firm in the letter to OPD officials.
