About Justin

Who better to act as an adviser to law enforcement officers who have suffered an injury on the job than a retired law enforcement officer who’s been through it all? Cooksey & Marenstein is incredibly lucky to have Retired LAPD Sgt. Justin Mudgett joining our team. After going through his own work-related injury that kept him off work for over two years, Justin gained invaluable knowledge and insight into all of the benefits available to injured officers, as well as the workers’ compensation process in general. He also gained a unique skill set while assigned as the IOD (injured on duty) Coordinator at Devonshire station, handling hundreds of injury claims.
After honorably completing his service with the U.S. Army in 1992, Justin joined LAPD Academy in 1993. During his 28+ year career with the department, Justin worked at many different stations in addition to Devonshire, including Foothill, West LA, West Valley, Hollywood, Rampart, and OVB Homicide (Cold Case Section); and he held a wide variety of assignments, including patrol, Special Problems Unit, Narcotics, and acted as Complaint Sgt. supervising the Rampart Administrative Office. Justin is proud of the knowledge and wisdom he accumulated during his law enforcement career and is looking forward to being able to give back by helping other injured first responders who are in need of vital information and guidance.
