a professional, private investigator agency dedicated to Criminal Defense Investigation and Process Service

As the Principal of Harrington Investigations P.C., Shane Harrington, PhD has become one of today's elite investigators. While Dr. Harrington continues to coordinate and conduct  intelligence gathering and investigative services throughout the Pacific Northwest, he has worked to narrow his focus. 

Dr. Harrington specializes primarily in criminal defense investigation. He is an analyst and field investigator who has concentrated his post-doctoral studies, research efforts and practical experience toward optimizing strategies and improving techniques in the field of Forensic Interviewing

In doing so, Dr. Harrington utilizes a hybrid approach. This integrates principles of Investigative Psychology and Forensic Victimology, along with varying theories of why people report...and perceivably commit, certain types of crime. Dr. Harrington uses this to substantiate a more concise investigative strategy. 

​Dr. Harrington's academic credentials are achieved by few and it is one of the many things that set him apart from other licensed investigators in the field.

Dr. Harrington applies a plethora of acquired skills and relevant expertise to every assignment.
