About

Masterchek Inc. is an MBE, DBE, SDVOSB, and SMWBE-certified second-generation family/veteran-owned investigative firm, with the desire to want all of our customers to feel as if they are part of the vision and goals of the company. When the founder Vincent Garrett started in the investigation industry in New York City, N.Y. in the 1970's he was determined to provide top-of-the-line service at an affordable price. In 2000, his son, Vincent Demps, our current owner took over the helm and has been committed to continuing in the same original direction. During his college years, he was called to active duty to serve in Operation Desert Storm in 1990-91 and spent several months assisting with running a P.O.W. camp in Saudi Arabia. After serving during this wartime conflict, Vincent returned to continue his education at Fisk University where he majored in Pre-Law and Business Management. After college, Vincent spent many years at Bass Berry Sims PLC, a 300-lawyer firm that represents numerous publicly traded companies and Fortune 500 companies working alongside one of Nashville's most well-known senior partners and a team of lawyers. At Bass, Berry, and Sims PLC, Vincent assisted with the complex litigation and investigation in many high-profile cases which were argued on some of the nation’s highest courts. He recently added college degrees in Cybersecurity and Homeland Security, which adds to the diversity of our firm. He is also one of only five certified private investigator trainers in the State of Tennessee. It is his diverse military, legal, and network security background that has allowed us to expand our services to meet the changing demands in the industry. At Masterchek we value each and every customer as they are not only the foundation that keeps our business going but also the reason we entered into the investigative field with the hope of giving them a service they can trust.
