Tommy, Thousand Oaks, CA

I was concerned about a situation involving my minor daughter and Doerner Investigations was there to help me. They are professional, compassionate and thorough in all they do. I would tell anyone needing answers to not hesitate and call Doerner to investigate.

This team of investigators is a first class operation. They keep the client informed the entire way through the process and get the job done no matter how big or small. Highly recommended to anyone needing some PI work done of any type!

Dana, Beverly Hills, CA

Doerner Investigations was recommended to me by a Criminal Law Attorney. My situation was very time sensitive and my family needed accurate information very quickly. Doerner Investigations was very professional throughout the entire process and sympathetic to the situation and continued to check in with me even after the services were complete. They were available to me at all times and helped us through the process in many ways. Much gratitude for Doerner Investigations, saved the life of a loved one. I highly recommend this company to anyone!!
