With an advanced degree in human behavior and clinical therapy from Columbia University, Joshua has over two decades of face-to-face experience as a Licensed Clinical Therapist helping people tackle their mental health issues. From divorce to depression, he has supported thousands in managing their mood and more serious disorders (i.e. Bipolar I and II, addiction, eating disorders, anxiety, depression), using a no-nonsense approach based on Beck’s Cognitive Behavioral model. Estrin created what is now recognized as the “Shut Up Philosophy” and applied it to coaching some of America's top CEOs and celebrities, helping them navigate the pressures of being in the spotlight and the impact this has on work-life balance. While still a staunch advocate for all things health/mental-health, he aspired for a deeper understanding of human dynamics. As such, he completed a Ph.D. in applied mathematics understanding that, “if you can’t measure it, you can’t manage it.” He began to quantify kindness, fear, safety and anxiety by using predictive, multi-regression and linear models of statistics in his work and research. His knack for numbers became appealing to some of the largest companies and social media platforms including OWN, Walmart, Pepsico, and Instagram, where he is known as the “Math Whisperer” and “Data Dude,” using consumer data to help brands make informed, responsible and fiscally sound decisions. Wrap this up in a neat package and you have the perfect mix of a right and left brainer narrating in his latest audiobook, “Shut Up and Listen to Yourself 2.0” (2021) available on Itunes, Audible, and Google Play, reminding everyone that they need to use action, ability and awareness, in that order, and listen to their inner expert.
