Our Story: A Letter from Our CEO

Daniel PerezPresident & CEO, Subrosa Investigations
I founded Subrosa in 2001 and serve as the company’s President and CEO. The origin of our company name is near and dear to me, as the literal meaning of “subrosa” is to behave in a confidential manner. And handling sensitive matters with the utmost discretion is the foundation of our company.

Early on, I developed a clear vision for Subrosa: To become an investigative agency known for its integrity, service excellence, and diversity of skills, and to be recognized across the industry as a work environment that fosters growth, collaboration, and innovation. Nearly 20 years later, our Subrosa team has turned that vision into reality.

The entire Subrosa team is driven by our company mission: To offer client-focused protection through investigative excellence. Living our mission and vision is only possible because Subrosa investigators, leadership, and administrative staff share a passion for helping you by delivering consistently excellent service and demonstrating the same commitment to superior work as you.
