Whenever our firm needs top caliber financial due diligence investigations we turn to Brosnan Risk Consultants. They are a unique firm in that they have married the disparate skills of highly trained forensic accountants, financial services investigators and NYPD detectives. This unlikely, but highly effective team, has worked wonders in providing actionable and accurate intelligence during our due diligence for our portfolio companies.

Brosnan is the go to security firm for TD Bank. Their security officers are professional, polished and highly trained. Brosnan is a pleasure to work with.

Greg Braca

Chief Executive Officer

As you the Rockland GAA grand opening drew tens of thousands of people from all over the United States and Ireland. I can't say enough about the service we received. Brosnan’s idea about leaving the "Brosnan SmartTruck" on premise was a big hit! It was a brilliant idea that supported our volunteer security unit. The two officers were very professional. Scott and Mateo were timely and carried a large amount of responsibility as our association had hundreds of thousands of dollars in supplies and electronic equipment to be safeguarded. The weekend was without incident.
