Chip Chambers
M.D. - Founder & President, DADA2 Foundation
Dr. Chip Chambers is the former Chief of Endocrine Surgery at Vanderbilt University Medical Center in Nashville, Tennessee, and continues to hold his clinical faculty appointment at Vanderbilt. Dr. Chambers' two children were diagnosed with Deficiency of Adenosine Deaminase 2 or DADA2 in March 2014, just one month after the first articles describing the disease were published in the New England Journal of Medicine. He has spent the last eight years making connections among clinicians treating patients with DADA2 all over the world, as well as patients, their families, and researchers studying the enzyme.
In 2016, Dr Chambers founded the DADA2 Foundation and held the Inaugural International Conference on DADA2 in November of 2016. As far as we know this is the shortest time between a disease being first described in the medical literature and the convening of an international meeting of this scale — less than three years. Nearly every physician and researcher who has touched this disease in some way was present. The Second International DADA2 Conference was held in November of 2018. There were 123 physicians and scientists from 25 countries including China, Japan, and Saudi Arabia, and 93 patients and families from 13 countries all in attendance. The Third International Conference on DADA2 was held virtually in November of 2020 due to COVID and there were over 500 physicians and scientists from 39 countries who attended.
Mary Makley
Executive Director
Mary Makley first learned of DADA2 in early 2016 when an acquaintance called her out of the blue to talk about the newly discovered disease his children had. Dr. Chip Chambers was in the formative stages of creating the DADA2 Foundation and wanted to talk about how Makley’s skills in documentary filmmaking might be put to use in helping spread the word about this new disease. That initial call led to years of collaboration on videos for the Foundation's conferences, website, and YouTube Channel.
In August 2021, after over 30 years of creating award-winning documentary programs, Makley put her communication and project management skills to work as Operations Director for the DADA2 Foundation. She has been working since then to build the basic infrastructure of the Foundation including IT, data management, communications, fundraising and program development. She is inspired every day by the stories of the DADA2 community.
