In 2014, Dr. Melk assumed leadership of CCHCI, an organization dedicated to the health and well-being of families living in the rural US/Mexico borderlands of southeastern Arizona. Since taking over as CEO, CCHCI has more than doubled in size and impact, now serving more than 30,000 unique patients a year, and supporting an annual budget of $50m. During his free time, Dr. Melk works with his wife and others on an all-volunteer nonprofit organization called the Rosa Vera Fund, which provides medical treatment for children and employment/education for healthcare workers in the Republic of Bolivia. Dr. Melk also relishes spending time with his wife and family, especially exploring the Arizona desert. He and his family live in Douglas, AZ, just ten blocks from the US / Mexico Border Wall.
