Dr. Chuck Dietzen, Founder and President
Dr. Chuck boasts a diverse career as pediatric physical medicine and rehabilitation specialist, international medicine enthusiast, entrepreneur, professor, and athlete.

Alyssa Rossodivita, US Programs Manager
A native of Cleveland, OH, Alyssa returns to the Midwest after a three-year stint in the sunny Rio Grande Valley, along the border between Texas and Mexico. She worked for Migrant Health Promotion, overseeing four state and federal grants that provided health education via the Promotor(a) (community health worker) model. Before that, she worked closely with physicians rural, south Texas to implement a chronic disease self-management program for low-income Hispanic residents. For two years prior to her work in public health, Alyssa was a 7th grade science teacher with Teach for America. It was her students and their health that ultimately convinced her to move back towards her interest in access to healthcare. Alyssa received a B.S. in Biology from Denison University. Like a good liberal arts student, she minored in Spanish and studied abroad in Chile, spent the majority of her time growing and coordinating the service trip program, and played with yeast to complete her senior thesis on DNA repair after UV exposure. She adores making jam and dancing the Texas two-step, and is ecstatic to be back again in the good ole Midwest!
Katherine Horn, US Programs Coordinator
Katherine joins Timmy Global Health following her senior year at Indiana University, where she graduated with her Bachelors degrees in Biology and Spanish, a certificate in Latin American Studies, and a minor in Chemistry. At Indiana University, Katherine volunteered with the IU Timmy chapter beginning her freshman year, traveling twice to Guatemala to work with Timmy’s international partner organization Pop-Wuj. Katherine’s time with Timmy sparked her interest in global health, Spanish, and living and working in developing countries – all of which led her to study abroad in Chile and Argentina for a year in college. Katherine is an avid traveler, a self-proclaimed adrenaline junkie, and she loves to bake. (Her cookies/brownies/muffins are always up for grabs at the Timmy office!) In the future Katherine hopes to attend medical school or get her Masters in Public Health. But for now, she is thrilled to be a part of Timmy Global Health and while at Timmy hopes to expand her knowledge of global health and gain experience in student outreach and non-profit programing.

She spent the next two years as a student leader in ND’s chapter, fostering a passion for global health and development work. Her experiences with Timmy inspired her to pursue a M.S. in Global Health at Notre Dame after graduating from the university in 2012 with a B.S. in Biology. Prior to graduating from the M.S.G.H. program in July 2013, Annie spent 6 weeks in rural Mokhotlong, Lesotho, evaluating the effects of a local NGO’s outreach program on antiretroviral therapy adherence.
