A Message from the GMDI President

April 2017


Welcome to the GMDI website! This is my first post as president of this wonderful organization and I want to thank so many people that have been involved in making GMDI the strong organization that it is today. The Latin phrase nanos gigantum humeris insidentes translated “standing on the shoulders of giants” seems apropos. It is often attributed to Sir Isaac Newton in 1676, who said "If I have seen further, it is by standing on the shoulders of giants."  As the current president of GMDI, I am standing on the shoulders of those “giants”, past presidents and members who have established this organization and created it what it is today.

GMDI was founded in 2005 by a group of dedicated metabolic dietitians under the leadership of Dr. Rani Singh (see the history tab). In just 12 years this fledging organization has hosted an educational conference every 2 years (the conference grows every two years), created an online nutrient analysis software for analyzing diets of patients with inborn errors of metabolism (MetabolicPro), written and published the first rigorous evidence guidelines for the nutrition management of PKU, MSUD and recently Proprionic Acidemia, and participated in advocacy and public policy initiatives to improve coverage of medical foods for our patients. We have accomplished a lot thanks to the founders and member’s dedication to our mission: to provide standards of excellence and leadership in nutrition therapy for genetic metabolic disorders through clinical practice, education, advocacy, and research. Thank you to Barbara Marriage, our past-president for her great leadership the past two years.

The current board of directors is hard at work to continue advancing our mission and I’m excited to see all that we will accomplish in the future. The Education and Communications committees are working on more webinar education opportunities. New initiatives are being planned in the research committee and the conference committee is working to ensure our 2018 conference will be exceptional. As a member, I would love to hear from you about what is important to enhance your practice and improve care for your patients. Please feel free to email me your ideas. It’s a privilege to work with the dedicated board members and our outstanding executive manager, Nancy Callanan. I look forward to working with all of you over the next several years!

Thanks for your support,

Melanie Gillingham

GMDI President
