The Wellness Team


Jesse Hartman
Role: Overseer of all things Wellness

I am 40 and a Washington native. I spent my senior year of college studying in southern France where I met my wife who is from Bogota Colombia. I learned French and Spanish and traveled extensively throughout the Americas, Europe, and Africa before venturing into the corporate world. After a 10-year career as Director of Training for a large company, I left to work with family and an amazing team at The Wellness Institute. I am the son of our founders, David Hartman and Diane Zimberoff, and am proud to lead a transition into a new era and growth of our organization.

Some notables include: I dropped out of Kindergarten and love photography, hiking, reading, learning, and all things Apple.

I get to be very creative in my job and wear many hats but my most favorite part of being here is meeting all the students!
