Founded & Managed by Kathy Griffin

[ Licensed Private Investigator ]


Kathy Griffin grew up in Houston, Texas and attended the University of Texas in Austin. A great part of Kathy's formation came from her dad, a Houston Institution. Michael Griffin is the consummate Houston booster. Much of his notoriety came from his ownership and management of Griff’s Pub near downtown Houston for 56 years -- the oldest Irish sports pub in Houston. He held rallies and parties for Houston’s sports teams, athletes, and even politicos. He’s semi-retired now, but he can still be found working with the Kgriff team by serving civil process. As Griff likes to tell people, “Be nice to your kids, you never know when you’ll be working for THEM one day!”


Kathy spent a lot of time at that bar, growing up… hanging out with dad. Whether it was St. Pat’s Day or a big playoff game, Griff would end up hiring some HPD officers for security. Over time, Kathy got to know and admire half of the Houston Police Dept. When she graduated UT, a lot of those guys were retiring from city duty and many started working as private investigators. One of them took a chance on Kathy as an intern, and the rest is history.
