The work behind the answer
The facts rarely announce themselves.
Before we decide where to look, we take the time to understand what brought you here and what a useful answer would actually change.
The facts may live in records, timelines, interviews, or details that do not quite add up. Finding them takes patience, sound judgment, and the experience to know where to look next.
Passant Investigations works with attorneys, claims professionals, businesses, and individuals who need more than information. They need a clear, reliable picture of what happened.
What we investigate
One team.
Many ways in.
Some matters begin with a person. Others begin with a record, a claim, or a question that will not go away. We build the work around what you need to establish.

Our story
More than three decades of finding what others miss.
Passant Investigations grew from a family tradition that began with Ralph Passant’s Business Information Company in 1969. In 1990, Ralph and his son Frank founded Passant & Passant and built a reputation for careful, thorough investigative work.
Rebekah joined the firm in 2018 and acquired the company in 2022. Under her leadership, Passant pairs that hard-earned experience with modern research tools, stronger nationwide coordination, and the personal attention that has always defined the firm.
Rebekah and Frank are licensed Pennsylvania private investigators. Passant Investigations is fully bonded and insured, and is a member of PALI and NAPPS.
