Extremely pleased with the results of INTERPROBE’s work for years.

I consider INTERPROBE my east coast ‘office.’ They have been an asset for surveillance and technical countermeasures for our firm for more than 15 years. Their support on cross-national cases and assignments unique to the Washington, DC area is highly valued.

They made a case against my client and I decided I better get them on my side for the future. I have used them ever since.

Great results by these investigators. They are accurate, ethical, and very persuasive in court.

…Ultimately, all of our cases requiring surveillance or a technical touch were referred to them. We depended on their capabilities and appreciated their reliability and fairness for more than 20 years.

My go-to investigators for more than 15 years; prior to receiving my judgeship.

After more than 50 years of heading one of the first and most recognized P.I. Firms in the Washington, D.C. Metro area, without reservation I can say that INTERPROBE was our first choice for contract surveillance and technical investigative services…

INTERPROBE is a stealthy surveillance team with great support personnel. They have delivered excellent surveillance service on sensitive domestic and international matters on numerous occasions.
