One of the oldest detective agencies in world

In 1924, the Mannheim Police Council MENG founded the Detective Agency MENG and is now one of the oldest and most renowned detective agencies in the world.

This laid a solid foundation for the successful establishment and the rapid and sustainable development among the top detective agencies in the world.

In 1961, the MENG detective agency was handed down to Rick Aschman and from then on it has been unceasingly developed.

By 1999, the visionary management of Rick Aschman had created 17 additional bases throughout Europe and 2 in the USA, which remain among the most successful and progressive detective agencies.

...very professional and reliable. The clear evidence that you have gathered has helped me immeasurably in making a very difficult decision with conviction. Thank you so much!

Stefan B.

HR Manager

I can only recommend the detective agency MENG to conduct private investigations! They are pleasant, focused and truly cared about our needs. Within a very short time they found the [...] information I needed about my deceased grandfather, which led me to finally find my birth father! I am so grateful for your help! Absolute professionals!

Dear detective agency MENG team! Your detective agency is by far the most thorough, compassionate, and methodical I have ever done business with. Your detectives are true masters of their trade and have repeatedly provided concrete evidence of several suspected cases and also offer excellent and reliable customer service.
