Our Team

Jason Herzog, MBA, is the CEO and Co-Founder of Holon Health. As a seasoned entrepreneurial leader and accomplished CEO, Jason has over 25 years of experience leading high-growth companies from conception to market leader status. He is passionate about driving systemic change that addresses the Quadruple Aim of healthcare: improving health, reducing cost, enhancing patient experience, and improving provider satisfaction.

Before creating Holon, Jason was the Founding CEO of Averhealth where it became obvious that the population of people involved in the criminal justice system who had a substance use disorder tended to have low healthcare literacy which impacted their ability to access services and the high-quality care they deserve. Not only did this cause lost time and financial burden to the individuals, it also led to increased costs for health plans and additional stress for justice systems.Jason knew that with the right approach and proper planning that the population could engage with healthcare in a way that increased patient satisfaction and improved outcomes for both patients and health plans. That’s why he founded Holon Health alongside Dr. Traci Sweet.

Prior to finding success building scalable healthcare companies at Averhealth and now Holon, Jason served as a Founding Partner at Creswell Partners, the VP at Harris Williams & Co., and has worked as a Financial Analyst and Business Associate. He has his MBA from the University of Chicago Booth School of Business and a BSBA From Rockhurst University.

Jason enjoys spending his time with his wife, children, and fur babies. His entire family shares a passion for active travel, snow skiing, and water sports.

Dr. Traci Sweet, Psy.D., is the Co-Founder and Chief Operating Officer at Holon Health. With over 30 years of experience providing operational and clinical leadership in the behavioral health and substance use disorder field, she has found success creating innovative healthcare solutions that drive results. For example, she pioneered the first integrated care models for SUD at Catasys, Inc. (now called OnTrak) in 2006 and has previously written evidence-based curricula for Spectrum Health Systems, Inc. (incarcerated individuals in treatment for SUD) and for the Commonwealth of MA (First Offender DUI program exclusively for women).

Dr. Sweet joined Jason Herzog in founding Holon because she wanted to create systemic and long-term change for a population that struggles with traditional healthcare models. She knew by combining the best evidence-based treatments to establish therapeutic alliances that she could break down barriers to care, build retention, and decrease stigma. “We needed to solve for longer-term engagement in treatment because high drop-out rates notoriously align with higher relapse and recidivism rates which hurt the patient, burden the criminal justice system, and cost healthcare systems. Holon addresses these concerns.”

Previously, Dr. Sweet was the COO and Head of Clinical Affairs at Kaden Health and the State Director of Operations for the Massachusetts Department of Corrections at Spectrum Health Systems, among other notable roles. She received her doctoral degree in Clinical Psychology and her MBA in Organizational Leadership and is also a Six Sigma Master Black Belt. She has completed fellowships at Yale University Psychiatric Institute and UPenn Medical Center. She has presented across the US at conferences like the Cape Cod Symposium on Addictive Disorders and the Disease Management Association of America and is a nationally recognized speaker and trainer in advanced techniques in CBT, motivational enhancement, relapse reduction, and complex disease management.

When not working, Traci enjoys spending time with her family and fur babies between FL and MA, traveling and adventuring, e-biking, and doing DIY projects.
