Mobile Defenders soon will break ground on a $7.5 million, 95,000-square-foot industrial building. The Grand Rapids-based seller of aftermarket cellphone parts will use half of the new building for growth and expansion. Mobile Defenders currently is located in a 20,000-square-foot facility at 3990 44th St. SE, Kentwood. Initially, Mobile Defenders will use half of the new building at 6155 East Paris Ave. SE and lease out the other half with the expectation to take over more of the building as the company grows. “Technology is even more critical today based on how society has changed,” Mobile Defenders CEO Jordan Notenbaum said. “Students day-to-day need their devices to work, especially when you’re studying remotely. Having your Chromebook go down for two days isn’t an acceptable option when you need to be online every day.”
