At Carlson Investigations, we customize each investigation to meet your exact needs.  Since we know the information and evidence we gather are vital to building your case, we present you with accurate and detail-oriented reports.
Criminal Cases
We specialize in many different types of criminal cases.  For many years, we have worked closely with local lawyers, district attorneys, and government agencies.  
Other Investigations
Although we specialize in criminal cases, Carlson Investigations has worked on a variety of investigations.  From missing persons to cheating spouses, we have the experience and tools to assist you with your case.
Background Investigations
A background investigation is crucial when you or someone you know may be involved with another person.  Dating or becoming new business partners are common and is important that you know that person's background.  
At Carlson Investigations, we know that you are putting your trust with us to investigate your case carefully.  Take a look at some of our testimonials from our current and past clients.
