We’re just over five months away from the PMSF 11th International Family Conference.

To help with your planning, please review this year’s Family Information Packet, which contains important details about the ‘United in Hope’ conference which will be held July 18-22 in Dallas, Texas.

You will find information about conference sessions including the Phelan-McPosium, Family Fun day, sponsorship opportunities and much more. The packet also includes information and a sign-up link for childcare.

We are pleased to announce that conference registration fees did not increase from our last conference in 2016.  In addition, there is scholarship funding available to help ease family’s financial burden.  The conference registration link is coming soon.


We are pleased to announce that Ronni Blumenthal will be joining us as our new Executive Director, effective Jan. 22.

Blumenthal, of Sarasota, was most recently the director of the Healthy Families, Healthy Children and Healthy Fathers program at the Jewish Family and Children’s Services in Sarasota and has worked extensively in the rare disease and disability communities in Florida and New York.

Susan Lomas, the Foundation’s Acting Executive Director, will continue to serve as the President of the Board of Directors and chair of the Global Partners Committee.
