Scott Leshin is the President and CEO of SJ Health Insurance Advocates.  Scott founded SJHIA after discovering firsthand how broken the health insurance industry is while trying to seek reimbursement for his son, Sam, who has cerebral palsy. 

Scott received his Bachelor’s degree from Syracuse University and Master’s degree from NYU Stern School of Business. Prior to founding SJHIA, Scott worked on Wall Street for both Morgan Stanley and Goldman Sachs. While working an intense full-time job, Scott was also managing the challenges and frustrations that came from navigating the health insurance bureaucracy. Through consistent and determined advocacy for his son, Scott continued to cultivate his knowledge and expertise of the health insurance industry. After achieving success for his son (who he still fights for daily) Scott decided to take his experience and build a company that would go on to help others.

Personally and professionally, Scott has made it his goal to help as many patients and providers as possible faced with similar needs and difficulties. Scott prides himself on managing a company comprised of competent, compassionate individuals who believe in the same.
