“When I want to know what is happening in North America about criminology I go to one person in particular - Doug MacGregor. Over time Doug has shown himself to be reliable, informed, astute and aware. I find his views invaluable.”
- David Wilson
Emeritus Professor of Criminology Birmingham City University
“Tenacious, determined, inventive and resourceful, just a few of the words that accurately describe Douglas. Most importantly he has an insatiable appetite for detail and the ability to think creatively, which are invaluable characteristics for somebody operating in this field. He sits firmly at the top of his game.”
- Peter Bleksley
Author & Broadcaster
"Douglas provides a superbly comprehensive service, full of detail and information. Not only is he thoroughly professional but he works quickly, which is a huge advantage for broadcasters and podcast producers."
- Mark Sandell
podcast producer "Beyond Reasonable Doubt" and "Manhunt- Finding Kevin Parle" for the BBC.
“Douglas MacGregor is a geographical wizard! His expertise is only overshadowed by his generosity. The Cold Case Investigative Research Institute (CCIRI) is a 501 c 3 non profit. MacGregor has donated his time and talents on numerous cases yielding answers for law enforcement and families. CCIRI has been fortunate to have The Geographical Profiler as an expert on numerous Cold Cases as well as developing cases. He has been spot on every single time!”
