Nashville PI Firm Expands Surveillance and Investigation Services

Paul Dillon Grows Private Investigation Firm With Expanded Services in Nashville

Nashville, United States – April 25, 2026 / The Dillon Agency /

The Dillon Agency, a private investigation firm based in Nashville, has announced a formal expansion of its service offerings under the continued leadership of founder Paul Dillon, adding structured programs for infidelity investigations, corporate inquiries, and enhanced surveillance operations to its existing portfolio.

A Founder With Investigative Roots

Paul Dillon launched the firm after building a career grounded in investigative fieldwork and a commitment to delivering factual, documented results for clients navigating sensitive personal and professional situations. His background shaped the agency’s approach – methodical, discreet, and centered on producing findings that hold up to scrutiny. That foundation has allowed The Dillon Agency to build a client base spanning individuals, families, and businesses across the Nashville area, each seeking professional-grade investigative support without the uncertainty of working with less experienced operators.

Expanded Services Address a Wider Range of Client Needs

The expanded service lineup now includes infidelity investigations, comprehensive background checks, covert surveillance, and corporate investigations. Each service is structured to meet the specific demands of its use case. Infidelity investigations, for example, involve documented surveillance work designed to give clients verifiable information rather than assumptions. Corporate investigations address concerns such as employee misconduct, fraud, and due diligence needs that companies face when entering new partnerships or managing internal risk. Background check services, detailed at thedillonagency.com/background-checks, provide individuals and employers with verified information on the people they are evaluating, whether for personal or professional reasons.

The expansion reflects the agency’s response to direct client demand in the Nashville market. Private investigator Nashville services have historically been fragmented across small operators with narrow specializations. The Dillon Agency has positioned itself to handle multiple investigative needs under one roof, reducing the friction clients experience when their situation does not fit neatly into a single category.

Paul Dillon on the Agency’s Direction

“We have worked with more than 200 clients across these service areas over the past several years, and the consistent feedback is that people want a firm that can handle the full scope of their situation rather than referring them elsewhere halfway through,” said Paul Dillon, Founder of The Dillon Agency. “Expanding our formal service structure around infidelity investigations and corporate inquiries reflects what we were already doing in practice.”

The agency operates with a small, experienced team and maintains a strict confidentiality policy across all case types. Clients working with the firm on surveillance or corporate investigation matters receive regular case updates and documented evidence packages upon case completion. The structured reporting process is part of what Dillon designed the agency around from the outset – ensuring that clients leave with information they can act on, not just observations that raise more questions.
