Cushman & Wakefield of Arizona, Inc. negotiated leases totaling 24,486 square feet for a commercial real estate advisory firm and a medical care company at 4141 N. Scottsdale Rd.

Fresenius Medical Care of Waltham, Mass., signed a 12-year lease for 15,317 square feet. Fresenius provides dialysis treatment through a network of more than 1,800 facilities nationwide. Keyser signed a 6-year lease for 9,169 square feet. It is relocating from 1048 N. 48th St. in Phoenix.

“Both tenants saw an opportunity to plant a flag in the heart of Old Town Scottsdale,” said Chris Latvaaho. “Scottsdale continues to attract innovative companies that see the value of locating their business in what has been branded as the live-work-play that is unique to Scottsdale and not easy to replicate anywhere else in the Valley.”

The anchor tenant is Aetna Life Insurance. With the two leases, occupancy will be 89 percent.

Latvaaho and Tim Whittemore of Cushman & Wakefield represented the landlord, an entity owned by certain affiliates of Westport Capital Partners LLC. Keyser was represented by company owner Jonathan Keyser. Fresenius was represented by Pete Wentis and Jim Greene of CBRE.
