Our Christian Mission and Investigative Standard
Living Waters Investigation & Protection exists to serve with excellence, humility, and an unwavering commitment to truth. Our Christian-based identity shapes how we treat clients, protect confidential information, and document facts, while our federal law enforcement and military JAG background shapes how we plan and execute investigations.
Our service philosophy is grounded in Luke 8:17: “For there is nothing hidden that will not be disclosed, and nothing concealed that will not be known or brought out into the open.” That principle means careful fact gathering, lawful methods, clear communication, and documentation that can be understood by counsel, clients, and the court.
Edgar Rios
Founder Leadership and Brand Identity
Edgar Rios founded Living Waters Investigation & Protection after 21 years as a Deputy U.S. Marshal, supported by military JAG training and disciplined federal law enforcement experience. As California PI #189675, a PI Qualified Manager, Registered Process Server #1962, and Registered Legal Document Assistant #0469 in San Bernardino County, he brings practical understanding of investigative work, field documentation, and professional accountability.
The firm is intentionally boutique: clients receive a defined plan, direct communication, and work tailored to the lawful objective. English and Spanish language support is available, and every case is approached with professionalism, confidentiality, and respect for the limits of California law.
