ERIC DUVEN
OWNER
Forensic Psychophysiologist
"The search for truth has guided my life. The importance of truth was instilled in me by my parents at a young age and hardened by my years as an Eagle Scout in Troop 100, chartered in Jamestown, North Dakota. A preponderance of my efforts in 26 years of law enforcement has been to find the truth of any situation. Nothing is made better or worse for having light shone on it; it is simply made real."
