Our Story

Global Investigative Services (Global) began in 1993 with a simple mission: to help employers make informed hiring decisions. What started as a small partnership between a healthcare staffing agency owner, a retired police officer, and a private investigator quickly grew into a licensed private investigation firm serving the Washington Metropolitan Area.

In the early days, background checks were conducted manually—via fax machines, courthouse visits, and phone calls. But between 1996 and 1998, Linda Mack and Marc Linchuck transformed Global by introducing secure online technology, expanding services nationwide and internationally, and positioning the company for long-term growth.

Today, Global is a PBSA-accredited background screening company, a member of Concerned CRAs, and adheres to Privacy Shield Principles and the EU’s GDPR. Under the leadership of CEO Marc Linchuck, Global continues to innovate and deliver trusted screening solutions to clients of all sizes, anywhere in the world.

Our company has been a client of Global Investigative Services for approximately 3 years. We were looking for a company who understood our specific requirements and whose processes were reasonably simple. Due to our fast growth and the immediacy of some of our custom requests, we have truly tested their ability to deliver. They’ve consistently exceeded our expectations when it comes to accuracy and quality, ease of use and customer support. I’m grateful to consider them a partner.

One of the best advantages we have had in working with Global is the integration with our ATS – so follow up with candidates and retrieval of reports are really seamless. We are confident that once we submit the request, the process is underway without delay. The staff who handle our requests are very proactive in following up with us if additional information is needed to complete any portion of the background check; they don’t just rely on entering activity notes in the system, but reach out and call us which shows that they are sensitive to our process and expected turnaround times. Their pricing is fair. And in a couple of unique cases, the leadership was very accessible to address questions and help us understand how to appropriately and legally follow up with our candidates.
