Unparalleled Expertise

The name Rosenallen is synonymous with trust, fidelity, and service. Our tradecraft and outcome-based approach was developed through years of real-world experience. That is why our clients turn to us again and again. We are the Oregon based investigative service other providers strive to replicate.

True Professionals

Our investigators and experts are PhDs, Medical Doctors, Certified Fraud Examiners, Professional Engineers, CPAs, and former Federal Agents; each is an expert in their field and an experienced investigator in their own right.
ROSEALLEN prides itself on the quality and training of its investigators. We believe in recruiting, investing, and retaining highly qualified investigators that thrive in our company culture and adhere to our strict standards. Unlike other private investigation organizations, ROSEALLEN never outsources its investigations to other private detectives or agencies. We will sometimes use our extensive network of vetted non-investigating professionals with specific expertise to bring the highest level of quality resources to your investigation.

Who Are We?

We don’t provide biographies or publicly identify our investigators. Much of our work requires anonymity and discretion, and we serve our clients best by staying out of the public eye. Rest assured that we will provide proof of our credentials and experience after you or your attorneys reach out to us. If you want to find out more, don’t hesitate to reach out.

How big are we?

We have nine full-time investigators and twelve contributing experts and specialists. We have an in-house computer forensics laboratory in Portland, Oregon, as well as accounting, data mining, and eDiscovery forensic tools. We regularly work with trusted polygraphers, psychologists, and chemical and biological forensic laboratories. We also have an investigator dedicated to liaising with local, federal, and international law enforcement resources.

Who are our Clients?

We have helped clients worldwide, from extensive corporate fraud investigations at Fortune 500 companies to pro bono cases helping families desperate for answers about their loved ones. We see it as our responsibility to help bridge the gap between traditional government-provided investigation resources and clients’ needs for resolution and answers.

Why We Stand Apart

From less-than-favorable portrayals in the media and news to glorified fictional characters such as Holmes and Poirot, the title of private investigator conjures up many different preconceptions. In reality, private investigators run the gambit of what skills and experience they can bring to the table. There are lots of other private investigation firms in Oregon, but we feel confident in stating that there is no other resource available to the public that brings more specialized experience and skills to complex investigations. We are literally experts in our field. At ROSENALLEN we do not compromise on who we bring into our organization. We look for the best and make every effort to invest in our personnel. We are not a referral service. Many fancy private investigation websites are in the business of selling leads to forensic and investigation service providers. That is not this site. We work the cases our clients bring us.

All of our investigators are licensed by the State of Oregon through the Department of Public Safety Standards and Training’s Private Investigator licensing program established under ORS 703.435, and meet all standards enumerated within that statute.

Everything we do is lawful and thorough and accountable to the most exact legal and professional standards. We’re fully licensed, committed to continuing education, and members of the industry’s premier professional organizations. Our investigators are responsive, thoughtful, and ethical professionals with a substantive understanding of our clients’ needs.

ROSENALLEN is a vetted affiliate of the GK Sierra’s iGIN © (IntelLink Global Intelligence Network ©) . Many of our investigators are also credentialed through GK Sierra‘s Joint Intelligence Partnership Program with INTERPOL (International Criminal Police Organization), enabling us to provide unparallel resources to bring to bear on your investigation.
