WEST BRIDGEWATER, Mass.--(BUSINESS WIRE)--J5 Infrastructure Partners (“J5”), based in Irvine, California, and Leaf Communications (“Leaf”), based in San Clemente, California, as of today, will begin doing business as Centerline. The evolution is part of a broader rebranding initiative announced by their parent company, Centerline, in May 2023.

“This is an exciting step for our organization, bringing the teams from J5 and Leaf under the Centerline brand”

J5 (now doing business as Centerline) is a telecommunications infrastructure company that performs both wireless and wireline services, including site acquisition, leasing, permitting, zoning, wireless and fiber engineering, utility coordination, and equipment installation.

J5, established in 2000 and acquired by Centerline in 2021, works directly with each of the top four wireless carriers in the U.S., as well as tower and other infrastructure owners and state and local governments.
