Keith Sherwood

Chief Financial Officer

Keith Sherwood, M.B.A

Keith joined the My Community Dental Centers (MCDC) executive leadership team as the Chief Financial Officer in 2007. In this role he is able to combine his 28 years of diverse finance experience to contribute to the expansion of My Community Dental Centers.

Keith completed his Bachelor’s Degree in Accounting and Master’s Degree in Finance from Walsh College in Troy, Michigan. After a brief time in the manufacturing business, Keith joined the ranks of the not-for-profit health insurance industry, where he worked for almost 20 years. Keith worked for Blue Cross and Blue Shield of Michigan and Priority Health before joining Community Care Plan (CCP) in 2001 as Executive Director. It was at Community Care Plan that Keith was first exposed to the rewards of working with the Medicaid population. Under his direction, CCP nearly doubled its membership and revenue, and was one of the most profitable Medicaid-only health plans in the State of Michigan. CCP also received the highly coveted Benchmark award from the State of Michigan.

After assisting with the sale and transition of CCP to a national insurance company in 2004, Keith became director of a multi-specialty health center serving the needs of the Medicaid and uninsured population. Under his direction, the operating results improved by $1 million by implementing LEAN process improvement strategies and open access scheduling, and by improving financial reporting tools. The highlight of this time, however, was the eye-opening experience of working directly in a setting that provides health care to the most vulnerable members of society.

Keith has served on the Board of Directors of the West Michigan Consortium and Kent Health Plan. He has also been a member of the Health Communities Access program (HCAP) of Kent County, Health Financial Management Association, Medical Group Management Association, National Management Association, and the Walsh College Association.
