Imagine what it would be like to live undercover for months at a time, and your success depends on building trust and detecting deception with some of the most dangerous people imaginable. That’s precisely what Pamela Barnum did for years as the only woman working undercover in a Drug Enforcement Unit of over ninety specialized police officers. As a result, she learned real-world techniques for building trust and interpreting body language.
When Pamela graduated from law school, she left policing and accepted a position as a federal prosecuting attorney. She spent countless hours in the courtroom, perfecting her trust strategies and body language expertise.
Following a successful 20-year career in the criminal justice system, Pamela studied corporate negotiations in graduate school. Now, she shares her expertise with others, teaching them how to improve their communication skills to increase trust within their organizations.
As a nonverbal communication expert and trust strategist, Pamela delivers techniques once thought of as a “secret second language” that participants can begin using immediately.
When you take decades of experience, including working deep undercover in narcotics, followed by a rewarding legal career, you get real-world strategies that help participants improve professional relationships using proven field-tested techniques.
Pamela shares her experience, research, and expertise with humor, honesty, and energy, blending actionable strategies with memorable stories.
She is also a featured expert and contributor in print media, radio, and television news programs in Canada and the United States and co-hosts on the hit TV show Building Bad. Pamela has also been honored to deliver two popular TEDx talks.
“POWERFUL action steps that can be put into play immediately! You are truly unique, accomplished, humble, and funny!”
“Dynamic. Engaging. Expert. All words used to describe Pamela Barnum by our conference attendees. Adding Pamela Barnum to your conference keynote lineup will take your event to the next level!”
“We are getting rave reviews after your presentation! I have had speakers for years and not one of them was as classy as you were. The results of the survey from your speech are in and you scored – Excellent! You might have broken the record for speakers!.”
“The easiest speaker I’ve ever worked with in my career!!! We’d love to have you back for a future event.”
“Fantastic presentation! We want you back to do another program for us!”
