You are here: About GMDI / History



In 2005, a group of experienced metabolic dietitians from both the US and Canada joined together to develop a professional organization to enhance and support the practice of genetic metabolic nutrition.  The first meeting of GMDI was started as the vision supported though the SERN  HRSA grant  at Emory University and the first meeting was hosted at at Emory through the Emory subvention grant after which it was developed as the non-profit organization. 

That organization, GMDI, is now incorporated as a nonprofit professional organization specifically for nutritionists and other health care practitioners working in this specialty. Today, GMDI provides leadership in nutrition therapy for genetic metabolic disorders through clinical practice, education, advocacy, and research. Membership in the organization provides opportunities for professional education, research, networking, training and peer support.

Fulfilling the Mission of GMDI began in April 2006 with the First Annual GMDI Metabolic Nutrition Conference. There have been  successful educational conferences every two years since that time that have provided presentations on the clinical management of genetic metabolic diseases and their biochemical bases, as well as interactive, hands-on opportunities for both experienced dietitians and those who were new to the field.
