PHOENIX–Columbus-based Nationwide Realty Investors has signed a lease with Arizona based health and wellness leader Isagenix International, LLC to occupy a 150,000-square-foot, single-tenant building at its master-planned Rivulon development in Gilbert.

The Isagenix lease agreement launches the first phase in the 250-acre Rivulon development located at the corner of Gilbert Road and the AZ Loop 202. The Isagenix building is scheduled to be completed in late 2015 as part of the approximately three million-square-feet of class A office, 500,000-square-feet of retail and hospitality uses planned for the project.

“We are excited to kick off the first phase of development at Rivulon with the construction of the Isagenix headquarters and significant infrastructure improvements,” says Nationwide Realty Investors president and COO Brian J. Ellis. “The commitment by Isagenix to locate its worldwide headquarters at Rivulon allows us get construction underway and will begin to establish Rivulon as a best of class business district.”

The recently announced four-story, 125,000-square-foot speculative office building originally planned for the Isagenix site will shift slightly east, and be located adjacent to the new headquarters. Construction on the speculative office building will begin in the second half of 2014 with anticipated completion in fall 2015. NRI also recently announced a 45,000-square-feet LA Fitness for the project. Construction of the LA Fitness building will begin this month, with anticipated opening in March 2015.
