With over three decades of service, Dan Ribacoff and International Investigative Group, Ltd. has developed a reputation in private investigation, recognized among leading firms in the U.S. The family-owned company provides investigative and polygraph services, focusing on discretion and thoroughness. A team of former law enforcement officers applies experience across a range of cases, from personal to corporate investigations, extending support to clients worldwide. Through its commitment to integrity, International Investigative Group has cultivated a base of clients who value comprehensive service grounded in investigative expertise.
A Family-Owned Approach to Investigations

Founded over 34 years ago by Daniel Ribacoff, International Investigative Group remains family-owned, bringing a personal approach that emphasizes attention to client needs. In contrast to larger firms focused primarily on volume, International Investigative Group centers its operations on the client, aiming to understand and address each concern uniquely. This individual-centered approach has shaped its reputation for thorough and careful investigation, fostering long-standing client relationships that prioritize discretion and trust.
A family-led business model fosters a culture of accountability, where team members share in the responsibility for upholding standards of service. This approach means clients often experience a more personalized service, an attribute that stems from the company’s family-owned structure. The result is an environment where both client satisfaction and rigorous standards of truth-seeking are at the core of each investigation.
Experienced Team Rooted in Law Enforcement

International Investigative Group’s team includes former law enforcement officers who bring years of experience in criminal investigations, applying practical insights to a range of client matters. From background checks to corporate fraud investigations, the team approaches each case with a structured, evidence-based mindset. Having a background in law enforcement equips these professionals with an understanding of investigative protocols that help them conduct thorough investigations while remaining compliant with applicable legal standards.
The investigative skills of the team are complemented by their experience with evidence gathering, case analysis, and case resolution. Clients, whether corporate or individual, can rely on the team’s established practices, which are designed to yield clear and actionable information. The combination of law enforcement experience with private investigation provides clients with a versatile approach to uncovering facts.
Polygraph Services: A Complement to Investigations
Adding another dimension to its services, International Investigative Group also provides polygraph testing. Conducted by trained specialists, polygraph testing can provide clients with a tool for verifying truthfulness in specific situations. The polygraph services are managed with attention to both accuracy and respect for clients, reflecting the company’s focus on ethical standards and careful handling of sensitive matters.
These polygraph services supplement the broader investigative offerings of the company, allowing for a more comprehensive service package that addresses client needs in various contexts. With skilled polygraph professionals and a commitment to confidentiality, the polygraph services provide an additional resource for clients who require verification beyond traditional investigative methods.
Extending Services Globally
Beyond its U.S. operations, International Investigative Group offers investigative services to clients around the world, expanding its impact beyond domestic cases. The company has developed the experience necessary to manage cross-border investigations, addressing complex issues like intellectual property disputes, corporate fraud, and asset recovery on an international scale. This global reach means clients in diverse locations have access to investigation and polygraph services tailored to a variety of local regulations and cultural contexts.
By supporting clients internationally, International Investigative Group has gained insights into handling cases across multiple jurisdictions, enhancing its ability to respond to a wide range of issues. This worldwide network offers clients a consistent service approach, regardless of location or case complexity, and speaks to the firm’s adaptability in meeting diverse client needs.

From investigative practices to polygraph testing, the company adheres to standards that aim to protect client interests and maintain high ethical standards. This emphasis on professionalism and ethical responsibility has been integral to building trust with clients who rely on the firm to handle sensitive matters with care.
