Executive Coach
Career Background

Greg retired in October 2016 as a partner from McKinsey & Company. During his 15 years at McKinsey, Greg focused his client work broadly on healthcare. He served health insurers, hospital systems, large employers, benefit consultants, and the federal government in the areas of population health management, Obamacare implementation, payment model design and implementation, revenue cycle management and payment integrity, clinical quality improvement and optimization. Functionally, he worked on business unit growth, organizational redesign, business model redesign, mergers and acquisitions, pre- and post-merger integration implementation, and strategic planning.

Outside of client service, Greg’s passion at McKinsey was leadership development. For four years, he served as co-dean of Inspire, McKinsey’s weeklong training program to help consultants become more inspired and inspiring leaders. In 2012, he helped design and then manage Firm Master Faculty, a selective, appointed position for ~50 partners who dedicate a significant amount of their time to teaching and mentoring colleagues.

During his last two years at the firm, Greg also served as global dean of faculty and head of faculty excellence. In this role he was responsible for recruiting, hiring, performance management, and program delivery excellence with oversight of ~300 partner faculty, alumni faculty, and external coaches and all of McKinsey’s leadership development training. He continues to serve as alumni faculty on Inspire and development programs focused on diversity and the success of women at the firm.

Greg serves on two nonprofit boards focused on education:  the Joyce Ivy Foundation, which focuses on opportunities for high-school women from the Midwest, and School Year Abroad, which sends high school students to France, Spain, Italy, and China for a year of study. He was previously on the board of Citizens United for Research in Epilepsy (CURE), and remains passionate about finding cures for the epilepsies.

Greg lives in Ann Arbor Hills with his wife, Toby, and two children, Casey and Ian. When not at Ross, you can often find him on the local roads pursuing his passion for cycling.
