Thomas Lauth and his team are, quite simply, incredible. Smart, creative, compassionate, efficient, and always there. When my friend’s daughter went missing, we engaged Lauth to find her, and they did. The nightmare Lauth helped shepherd us through didn’t end there, however. The next phase involved getting the endangered young woman to safety. I still marvel at the quick-thinking, creative solutions Lauth and his team of caring experts came up with in the seconds, minutes, hours and days that followed. Lauth also acted quickly to provide a deep list of contacts (mental health, social workers, lawyers, advocates, organizations in Indianapolis where we were) they help us secure the young women’s complex needs. For our unexpected, volatile, chaotic and heartbreaking situation, it was so very good to have Thomas Lauth study expertise to count on. Can’t ever think him and his lead investigator enough.

“The information Lauth Investigations was able to obtain in regards to the unethical activities occurring at one of our warehouses was exactly what our HR Director needed to begin termination procedures on not just one individual but an entire department. I would definitely recommend them!”
