Client Testimonials

I have used Sandlin Private Investigators many times in the past and have always been very happy with their work.  I am now engaging Sandlin for all of my law firm’s private investigative needs.  From simply serving someone with their court date, to needing complex investigative services performed on a party opponent, this is the team for you.

Aaron Freeman, JD, The Freeman Law Office, LLC

I first met Jack Sandlin when he worked at the Marion County Prosecutor’s office leading their investigative efforts.  In his career at the Prosecutor’s office and at the Indianapolis and Southport Police Departments, Jack represented the best in law enforcement.  He has shown himself to be a man of integrity who has dedicated his life to God, his family and community.   Jack’s professionalism as an investigator and commitment to his clients has always been exemplary.  As a fellow investigator, I’ve worked with Sandlin Private Investigators on a variety of complex, criminal and civil matters over several decades, both in the U.S. and internationally.  They have shown themselves to be valuable assets with excellent resources and knowledge.
