GrowOptimism leverages the best Behavior Science and Optimism research to help individuals and companies get better results.  Behavior Science helps understand human decisions, and why we sometimes suboptimize opportunities (e.g., cognitive biases, brain capacity, emotions).  


We deliver science-based solutions that drive higher performance through consulting, training, coaching, as well as a simple, fast and reliable test to help you identify people with more optimistic perspectives.  Here’s our virtual team.

Laura Heft, Ph.D. is the founder and CEO of GrowOptimism, LLC.  She has extensive experience working in Fortune 500 companies on behavior science consulting, leadership, selection/assessment, and employee and organization development.  Her Ph.D. is in Industrial/Organizational Psychology from the University of Missouri, St. Louis. 


“I have been an avid believer in the power of optimism for many years, which included conducting published research in a corporate setting over 20 years ago.  However, more recent experiments leveraging optimism to help myself and others overcome some of life’s challenges ignited a drive to deliver the message to a broader audience.  That’s why GrowOptimism, LLC was created.”
