Dan's eldest daughter Amelie was diagnosed with Tay-Sachs in 2011 at 15 months of age and upon finding that there was no dedicated advocacy group providing support for families affected by this disease in the UK he set set-up the Cure & Action for Tay-Sachs (CATS) Foundation with his wife Patricia. Since the group was launched, they have been able to grow The CATS Foundation so that it now offers a variety of services to its family members and has been actively involved in the research investigating therapeutic treatments for Tay-Sachs and Sandhoff disease. In addition to this, Dan is the one of the founding members and Chairman of the European Tay-Sachs and Sandhoff Charity Consortium which brings together all the European patient groups leading the fight against the diseases and is part of the team establishing the IGGA, a global organisation bringing together all the advocacy groups for GM1 and GM2. Dan is fully committed to leading the charity towards its goal of finding a treatment so that there is hope for those families affected by Tay-Sachs and Sandhoff in the future.
