Dr. Debra Dupree, the MINDSET Doc, transforms challenging confrontations into learning conversations, taking the ‘sting’ out of conflict.  She saw her own family-owned business embroiled in differences, leading to dashed dreams, damaged relationships, and broken hearts.  She turned these early experiences into a lifeline for smart people who fear conflict by bringing in the brain science behind blow-ups and emotional reactions.  She now turns “fear and conflict into peace and profits.”

Her goal is to help professionals in all walks of life to build climates of courage and curiosity for the people they serve, and set the tone and model the way for meaningful exchanges to “learn, listen and grow” to stop the cycle of conflict.

Dr. Debra is a Dispute Resolution Specialist, Conflict | Leadership Coach, and International Trainer |  Keynote Speaker.  She hosts the podcast ‘Decoding the Conflict Mindset’ to bring ‘thought leaders’ to her community worldwide to gain insight when high emotions run high and tough negotiations are at stake.
