“We had Dr. Christiansen present to our officers and I heard positive feedback for a year afterwards."
— Boulder County Sheriff's Office
Dr. David Christiansen
  is a licensed psychologist (CO License #1900)  in private practice, and has done more than 30 years of work with private clients and consulting with law enforcement and first responders.
  Dr. Christiansen taught for twenty years as an adjunct faculty member at the University of Northern Colorado and he has provided training to thousands of police officers, sheriff deputies, firefighters, paramedics and EMTs, social workers and attorneys, all of whom are exposed to trauma either firsthand or vicariously as a result of their work.
 His training is thorough, personal, humorous, detailed, and filled with many take-home points; his evaluations are strong indicators that his message makes a difference.
“I believe he truly understands and appreciates the often difficult situations that law enforcement officers and emergency medical professionals are routinely faced with.”
