Tri-County Health Department (TCHD) is the local public health agency for Adams, Arapahoe and Douglas counties providing a wide range of public health services to 1.4 million residents in the Denver Metropolitan region. TCHD promotes, protects and improves the lifelong health of individuals and communities through the effective use of data, evidence-based prevention strategies, leadership, advocacy, partnerships, and the promotion of health equity. Since research has shown that a person’s health and the likelihood of becoming sick are greatly influenced by powerful social and economic factors such as access to stable housing, economic opportunity, and education, TCHD believes health is at the forefront of Mile High Connects’ multi-sector problem-solving approach to these complex topics. Participation with Mile High Connects furthers TCHD’s efforts to bring health considerations to policy and system change work in non-health sectors. A well-planned regional transit system will not only improve housing options, access to jobs and access to good schools, it is the vehicle for good health.
