Larry joined Marin Consulting’s team of professional instructors in 2008 and after retiring from POST rejoined the team as an associate before deciding to take the reins as the owner and director.  Our team believes that supervision is the key to maintaining and enhancing law enforcement professionalism at all levels and Larry is excited to again be a part of this team of exceptional and highly respected instructors.
