The company arrived in an unmarked SUV. The person first walked through our office and property to ask us what we wanted searched.  They then explained that the dogs would be picking up on odors. They came with two search dogs. We have a small office, so they went through first with one dog and then the other. Very helpful and useful. I would definitely hire again.

Abruptly one day, in the face of a threat, I was advised by a wise and seasoned law enforcement professional to consider hiring a private investigator and referred me to Doerner Investigations.  This was for me a foreign concept; but I am glad I listened, and grateful that I consulted Amy Doerner (Doerner Investigations).   I would expect a qualified investigator to be very smart, coupling impressive analytic skills with right-brain intuitiveness.  On those scales, Amy is impressive.  Her questions were incisive, revealing, astute; her search was focused and thorough.    She understood financial limitation, and prioritized clearly, distinguishing the essential, the preferable, the optional.  While I found Amy’s investigative abilities and style outstanding, something else sets her apart:  Character.  She is personable, kind, patient.  She understands fear.  She has integrity.  She takes the safety of her client very seriously.  Besides investigating, she took time to advise me on security measures; took even more time to follow up with me to make sure I landed with the right professionals; AND followed up with them to make sure they were on task. She has my appreciation and my respect. And I sleep soundly again.  I highly recommend her!

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.

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!!

Doerner Investigations has twice helped me locate my daughter who suffers from mental illness. Amy Doerner’s ethics and concern go beyond what I would have expected. She is trustworthy, intelligent and intuitive. She kept me informed during the search and was sensitive to both my worries and my daughter’s paranoia. She continues to follow up and check in with me, and continues to “keep an eye out for my daughter.” She is a dedicated professional and a friend.

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!

I highly recommend Doerner Investigations if you are in need of PI services. As an adoptee, I was able to find missing links that have eluded me for years! They were extremely professional and highly committed to my case. I am forever grateful and would not hesitate to use them if needed again.
