Our Leadership

Rosa Vera Fund Founder and CEO Dr. Jon Melk

Jonathan Melk, MD — Chief Executive Officer of the Rosa Vera Fund (RVF)

Dr. Jonathan Melk first traveled to Montero, Bolivia, as a Cornell University medical student in 2003. During that trip he worked with the RVF’s current Bolivian partner, the Consejo de Salud Rural Andino (CSRA). Jonathan was inspired by the dedicated leadership and work of the CSRA, and astounded by what could be accomplished in Bolivia with limited funds. During the second year of his residency training—and with the generous support and encouragement of family and friends—Jonathan founded the Rosa Vera Fund. The RVF has been an integral, challenging and tremendously rewarding part of his life ever since.  Jonathan is the medical director of the Southern Arizona Children’s Health Project and a full-time community pediatrician for the nonprofit organization Chiricahua Community Health Centers, Inc. that serves the rural southeastern Arizona/ Mexico borderlands. In his off hours, you will find Jonathan and his wife Dr. Darlene Melk (RVF’s Chief Medical Officer) exploring the deserts and mountains of the Southwest with their sons. Jonathan is deeply grateful to the RVF’s Board, to the CSRA, and most of all, to the generous donors who made our important work possible.

In my experience, development work is most effective when efforts are led by local leaders. I am inspired by the willingness and determination of our Bolivian colleagues to take on these challenges in a corner of the world that desperately needs their dedication and expertise. — Dr. Jonathan Melk, Founder and CEO of the Rosa Vera Fund

Darlene Melk, MD — Chief Medical Officer of the RVF

As the daughter of a political refugee from Cuba, Darlene Melk was able to gain an inside view of the barriers her mother experienced when trying to access services for her family. Not only was it difficult to communicate at times, but the culture was entirely new to her. Helping the underserved would become Darlene’s focus after graduating from the University of Arizona medical school. Knowing that intervening early in children’s lives ensures their best chance for a healthy future, Darlene has focused her career on those children with the least access to quality medical care. She currently works on a mobile medical clinic in southern Arizona and part time in south Florida, both partnerships with the Children’s Health Fund. Working with the Rosa Vera Fund has allowed her to expand her practice of medicine to some of the most disadvantaged children in Latin America.
