Professional Title: Director, Gonda Diabetes Center

Matthew Freeby, MD is an Assistant Clinical Professor of Medicine, Director of the Gonda Diabetes Center and the Associate Director of Diabetes Clinical Programs at the David Geffen UCLA School of Medicine.

He completed his residency in internal medicine at UC San Diego and a fellowship in Endocrinology, Diabetes and Metabolism at Columbia University. After training, he joined the faculty at Columbia University specializing in diabetes care and research at the Naomi Berrie Diabetes Center. There, he collaborated with basic researchers and has published in diabetes-related stem cell research and the evaluation of non-invasive measures of beta cell mass. He has also reviewed the benefits of continuous glucose monitoring and evaluated best methods in transition of young adults with type 1 diabetes to adult care.

At UCLA, he has collaborated with faculty and staff with the aim to improve diabetes access and care within the health system. He works closely with the diabetes education team who provide consultation in one-on-one settings or in workshops. Additionally, he leads other programs targeting high risk patients with type 2 diabetes with the goal of increasing access to Endocrinology physicians. He also leads an annual UCLA Professional Diabetes Symposium geared toward primary care providers and allied health professionals hoping to learn more about the care of diabetes and its associated co-morbidities.

In addition to program building within UCLA Health, he sees patients with diabetes at the Gonda Diabetes Center in Westwood and the UCLA Diabetes Center of Santa Monica.
