Board of Directors

The MDF Board of Directors is comprised of volunteer leaders from the public and private sectors, many of whom are either living with myotonic dystrophy or have loved ones with the disorder. Their families represent many manifestations and varying degrees of severity of the disorder. The Board works closely with the MDF Staff and Scientific Advisory Committee to offer insight into the subtleties of the disease.

Jeremy Kelly

Board Chair & Lifetime Trustee

Jeremy Kelly came to the States from England for college and now lives in Mill Valley, California with his American wife, Erica, and two young sons, Jack and Ben—both of whom have childhood-onset myotonic dystrophy. Like many individuals, Erica—with the mild form of DM—might never have known she has this disorder had her children not been more affected than she. After an 18-year career at JP Morgan, Jeremy joined the management team of Provident Funding, where he serves as Chief Financial Officer. In May 2007, he started a one-man fundraising effort by seeking pledges for his daily bike commute—32 miles round trip—with the goal of reaching 5,000 miles in one year. His idea proved to be very successful, with more than $150,000 raised. In attendance at IDMC-5 in Quebec, he is also a founding member and served as MDF Treasurer from 2006 to 2009.
