About Us

PUSH is the first fair and effective progress-based health and wellness incentive program. The program leverages principles of behavioral economics to effect health behavior change, producing tangible benefits for organizations and their valued employees. This unique incentive management concept was developed by Dr. Greg Vachon, a practicing internist with over 25 years of experience in clinical practice and behavioral health counseling.

Founded in 2011, PUSH was one of 10 companies selected for the inaugural class of Healthbox, a prestigious accelerator program that supports innovative healthcare startups. The program was funded by strategic partners that include Walgreens, BlueCross BlueShield Venture Partners, Merge Health Care, and Sandbox Industries. Following Healthbox, the PUSH team moved to 1871, home to Chicago’s most innovative young companies. Today, PUSH works with organizations across the country to motivate employees to improve their health.

Dr. Vachon later moved to the Center for Partnership Medicine, Northwestern Memorial Hospital’s executive wellness practice, while completing academic work in public health.

In between raising three kids and running a successful wellness business, Greg still finds time for regular swimming and weight training. Stairmaster sessions ready him for climbs up the Adirondack mountains every summer. He may be the oldest member of the PUSH team, but he’ll tell you that he’s the fittest.
