Suburban P.I. is a licensed and insured full service Private Detective Agency, owned and operated by Steven Yahnke and the Yahnke family, with a special emphasis on customer service.

Suburban P.I. incorporated in 2004 and has been building a successful agency ever since. We are proud to say that we still serve our very first client!

In January 2013, Suburban P.I. Inc. opened its second office at 75 Executive Dr., Suite 421, Aurora, IL 60504 (on the outer drive at Westfield Fox Valley Mall/Rt. 59). Now with two locations, one in Kane County and one in DuPage County, Suburban P.I. is even better situated and equipped to service all of your investigative needs.
