Our Andersonville office is located at 5149 N Ashland Ave, Chicago, IL 60640  which is exactly 2 miles north of Wrigley Field. While we don't have a designated parking lot, there is plentiful non-metered street parking on Ashland and the immediate side streets.

We share an entrance with Great Lakes Clinical Trails. The main door is on Ashland, just south of Foster Ave under the blue awnings (Note: there is no common ownership between Gilleon Health and Great Lakes Clinical Trials).

We accept new and existing patient appointments at this location Tuesdays and Thursdays. Our administrative team is available Monday - Friday at 773-832-8700 or FrontDesk@GilleonHealth.com.

Our general fax is 312-253-7491 and our fax number specifically for prescription request is 312-967-5879.
