Marcus Holloway
VP of Business Development
Marcus Holloway comes from a family with deep roots in maritime security, representing the second generation to build a career protecting people and property. He retired in 2021 after more than 25 years with a coastal sheriff's department, where he rose to the rank of lieutenant in the marine enforcement division. Over his tenure, Marcus worked a wide range of assignments that included harbor patrol, dive recovery operations, and a stint as a field training officer responsible for developing newer deputies.
In his final decade of service, Marcus commanded a regional maritime smuggling interdiction unit and later helped stand up a joint task force focused on dockside cargo theft and port corruption, working alongside federal partners and customs officials to dismantle organized trafficking networks operating along the waterfront. His assignments frequently demanded long-term surveillance, confidential informant management, and coordinated takedowns across overlapping agency lines.
Marcus also handled sensitive internal affairs matters and high-profile fraud cases, work that sharpened his eye for documentation, interview technique, and building cases that hold up under scrutiny. That same rigor now anchors his approach to private sector investigations.
Since stepping away from public service in 2021, Marcus has applied his background to corporate due diligence and insurance fraud work, with a growing specialty in supply chain and asset protection investigations. At Encyphir, he draws on that experience to lead business development, showing clients how disciplined, professional investigations can safeguard their operations, their bottom line, and their reputation.
