Letter from the CEO:

Dear Colleagues,

I am very pleased to introduce you to Subrosa and provide some insight into our story.

I founded Subrosa Investigations in 2001 and currently serve as the company’s President and CEO.  The origin of the name Subrosa is very near-and-dear to me as its literal meaning is to behave in a confidential manner.  Thus, practicing discretion in handling sensitive matters of every kind is the foundation of our company.  Through the early years of Subrosa, I developed a clear vision for how the investigative agency would operate.  We would become a company that was recognized for integrity, excellence in investigations, diversity in our skills, and we would be known for fostering an environment of growth, collaboration and innovation in the investigative industry.  I can say that after almost twenty years in business, our Subrosa team has turned that vision into a reality.

Living this mission and vision has become possible because Subrosa investigators, leadership, and administrative staff share a common passion for helping our clients and consistently delivering excellence.  We are a group that is driven by our company mission: to offer client focused protection through investigative excellence. This passion is demonstrated through the level of excellence that Subrosa delivers which is the same underlying commitment our clients have to superior work.

We are glad you are exploring our website to get to know us better.  Please be sure to reach out and let us know what we can do for you.
