“We engaged Theia Investigations to do an “Alive and well” check on a very reclusive relative.  This was a sensitive case and [they] carried out our instructions to the letter, always consulting us before proceeding to the next stage.  We were really pleased with [their] work and he achieved results in quite difficult circumstances.  We will use his company again and recommend him to others."

"Due to an unfortunate turn of events, I had to hire a private investigator. I mulled it over for a long time, thinking it somehow untoward and shadowy. I had never had to do anything of this nature before. When I finally mustered the courage to call, [they] were so congenial and patient, it was like speaking to a friend who already knows the best AND worst sides of you. Within one day [they] made progress and by the end of the week [they] got me 99% of the info I needed. As with the previous reviewer, I did not price this out in advance so I can't compare to others. I knew, however, that if I hired a licensed and certified person, I would have to pay a professional's rate. It turned out to be about the cost I expected. [Theia] is a class act and will make this as easy for you as possible. "

"I recently used Theia Investigations, and am extremely satified with the services rendered. The services I received were prompt, professional, and in as much detail as could be expected. I have not used this type of services before, and therefore cannot judge the rates charged. If I ever need services in the Bay Area again, I will definitely use Theia Investigations. Thank you [Theia]!"

"After having dealt with numerous sleepless nights, wondering where my teenage daughter is, and whom she is with, I turned to Theia Investigations after a strong nudge from a dear friend. I was told that they could install a type of software on my computer so that I could monitor, without being detected, who my daughter was chatting with, and what types of topics she was engaged in. What I learned was shocking. After I confronted my daughter about this, she threatened to run away. Upon hearing this, I called back to Theia, and had them install a gps tracking device on my second vehicle, the one my daughter uses. When she followed through on her threat to leave, I was able to track her every move, and I had local law enforcement knock on the door of the "crash pad" where she was staying. Not only did I get her home safely, I was able to find out who she was hanging out with, and ultimately put a stop to it...they were substantially older than she! Thank you Theia! Your service is timely and necessary."
