Great Lakes Professional Investigations, LLC

Fantastic experience: Periodically, we will reach out to Great Lakes to assist us in a case matter. Jacob has always been aware of our desire to have the job done right. They have a tendency of doing things opposite of what the sheriff has done and we like that. It keeps our success rate up, and always leaves the door open for us to reach out for them when we are at a time of need.

Fantastic experience: Jacob is an outstanding helpful source for important information regarding legal research matters. Even provided some key information as a courtesy to help me.
