In 2018, our good friends at Great Lakes Clinical Trials were kind enough to let us sublease part of their office in Andersonville located at 5149 N Ashland Ave, Chicago, IL 60640 to start Gilleon Health. In the Spring of 2019, we opened our permanent office at 2831 N. Milwaukee Ave, in Logan Square and our staff began splitting time between both locations.

When our sublease expired in November of 2019, we closed the Andersonville office and officially moved to the Logan Square location fulltime.
