About Us

Our Story

Detective Services (DS) owned and operated by private detective Mark Grover in Melbourne, one of Australia's most sought after and successful private investigators.

Setting up a practice in 1990, Mark placed an advertisement in the Yellow Pages under 'Private Investigators', followed up with a mail drop in Melbourne drawing in a core group of clients which enabled Mark to swiftly prove his abilities, gaining him a respected and distinguished reputation throughout the private and corporate worlds for his professional and intuitive approach.

In 1992, Mark was hungry to expand his knowledge beyond the local standard practices and invested in travelling the world; networking with industry leaders, fine tuning his investigation skills, gaining exposure to numerous blue chip companies and assisting on diverse cases such as espionage and fraud matters. Bringing back vast knowledge, skills and technology at the time unavailable in Australia brought innovation home and moved the industry forward in leaps and bounds.

In a dramatically changing and evolving technological world, the next decade offered opportunities to continue to build on the skills and industry expertise Mark had established his reputation on. Detective Services had to expand in order to deal with demand. Mark head hunted some of Australia's most sought after up and coming private detectives, providing training and mentoring them to use his finely honed methods and systems of investigation.

Building and growing the practice which today has a network covering every city & outback town in Australia to a vast international group of industry colleagues across; the United States, South America, Europe, Africa and Asia. The practice continues to grow and build on the foundations established by Mark, ensuring both private and corporate customers have access to the most advanced network of constructive, active and experienced investigators the world over, who are engaged in traditional and emerging forms of investigative solutions enabling Detective Service to offer unrivalled service and results.
