About Us

Founded in 2006, Tx Xchange was started to give healthcare, wellness, and fitness professionals the ability to deliver more engaging, participatory, and effective care to their patients or clients online. As a supplement to clinic-based care, case studies have proven Tx Xchange is very effective at increasing participation and enabling more cost-effective outcomes. During this transformational time in healthcare, Tx Xchange is focused on helping its customers meet the demands of a challenging marketplace, improve the quality of care they deliver, and increase revenue by "repackaging" and charging for their services online. The software is used by health, wellness, and fitness providers in United States, Europe, and Asia.

Tx Xchange's founders, Dr. Mark Barnes and Jonathan Epstein, are building a company culture committed to innovative patient-centric healthcare models that increase patient participation, enable more cost-effective outcomes, and help providers diversify revenue streams.
