About Martin’s Private Investigations
Since 1995, Martin’s Private Investigations has delivered professional investigative and protective services to clients throughout California and Arizona, including corporations, legal professionals, and private individuals.
With a foundation built on decades of experience in civilian law enforcement, military law enforcement command, and executive protection operations, MPI provides fact-based investigative services and risk-informed assessments intended to support client awareness and decision-making.
MPI conducts risk assessments for schools, critical infrastructure, regional hospitals, and corporate facilities, identifying observable conditions, potential vulnerabilities, and areas for consideration. These assessments incorporate structured analytical methodologies, including the CARVER+ methodology, to evaluate criticality, accessibility, vulnerability, and potential impact across identified assets and environments.
Our approach is designed to assist clients in evaluating risk, prioritizing threats, and implementing appropriate mitigation measures aligned with their operational needs, resources, and duty-of-care responsibilities.
All investigative findings and assessments are based on information available at the time of review and are provided to support situational awareness and informed decision-making. MPI does not guarantee the prevention of future incidents; however, our work is intended to help clients better understand potential risks and available mitigation strategies.
We maintain strict confidentiality and deliver all services with professionalism, discretion, and adherence to applicable standards.
