Professional Associates of Downtown Investigations

There are many cases that require multiple Detectives, which would be impossible to have on staff, full time.  Many Private Detective Agencies are operated in small capacity.  Most are single person operations, while some may have a few employees. Larger Detective Agenices that have up to 15 employees, typically do volume work from insurance companies that supports their business model.


We're proud of being a small firm with a big reach.  


Detective BiIlard has built a personal network of Licensed Private Detectives, in Massachusetts, Michigan, across the country and internationally.  Our Licensed Detectives have years of experience and specific talents in the investigatiion field that make them valuable assets on casework.  Some are expert surveillance investigators, seasoned interviewers, skilled researchers and more.  


Regardless of the team that needs to be assembled, we have pre-selected access to the most qualified Detectives for any assignment, which saves our clients time and investigative budget.

Client Testimonials

“Based on what little we knew, we were at a disadvantage.  The information that Dowtown Investigations provided proved inavaluable to our case at trial.  Completely changed the game.”​- Attorney Client, Boston, MA
"When I called Downtown Investigations, I had no idea what to do.  I never needed any services like this before.  I was at the end of my rope and it was nothing that the police could get involved in, "until I had proof," they said.  The time that Downtown Investigations spent to explain the process and understand my case was kind of amazing, but the results of the investigation were even better.  The police detectives were blown away with the evidence we now had.  They were finally able to do something and my sleepless nights were over." - Private Client, South Boston, MA
"If I had not involved Downtown Investigations, I know my family would not be together today.  They got the proof I needed after my mind was racing with wild assumptions." - Private Client, Arlington, MA
“We did an internal investigation that yielded no results.  Then we hired a Private Investigation firm to conduct a full investigation, which did not provide any additional information or results.  On the advice of our council, we hired Downtown Investigations so that we could demonstrate our due dilligence to our insurance company in case of potential liability. Downtown Investigations worked professionally and timely and determined who was responsible for sabotaging a joint venture partnership and leaking sensitive company documents under an alias.  We were not expecting the results they provided.  We were shocked that they were able to get a full written confession from an employee that had been employed with our company for 26 years.” - Corporate Client, Prudential Center, Boston, MA​
"We hired Downtown Investigations to conduct a high-level background investigation for an employment candidate that would be placed into a sensitive role.  The due diligence and presentation of the information uncovered was unmatched to anything we have seen in the past.  We are satisfied with the results and will be using Downtown Investigations again."  - Corporate Client, Michigan
