Private Investigators and Process Servers in Pennsylvania


We are Private Investigators and Process Servers with multiple locations in Southeastern Pennsylvania and beyond. Notaries available where specified.

It is a common misconception that private investigators and process servers are required to have an office and license in each county in Pennsylvania. While we are headquartered in Lansdale, PA, we are licensed to serve the entire state of Pennsylvania – and we do! From Philadelphia to Berks County, Montgomery County and beyond, our friendly staff is ready to assist you. Read what some of our clients from Southeastern Pennsylvania had to say here.

We have received detailed investigation reports…within a 48 hour period. These return rates – along with the attention to detail – are evidence of Michele’s work ethic. Finally, Michele’s prices – and more importantly – her quotes, are what I have really come to appreciate. With Harris Investigations, you know what you are getting.
