HENNET was founded in 2005 and registered in 2007 as an NGO by the NGOs Coordination Board with a goal of coordinating and networking the CSOs in the health sector. There was as felt need among the players that a common platform among the CSOs dealing with health issues in Kenya was necessary for purposes of collaboration, sharing of experiences and advocacy and hence the formation of HENNET.

HENNET has a membership of over 112 members as of 2023 which comprises of both local and international Non-Governmental Organizations (NGOs), Faith-Based Organizations (FBOs) and Research Institutions working in all the 47 Counties in Kenya but all focused on health and health related issues. The various members have diverse health-related interests but all share on the vision of having a healthy Kenyan society.

HENNET is governed by a Board of Directors with an executive committee as defined by the network’s constitution. The board monitors and evaluates functions of HENNET based on its objectives as spelt out in the strategic plan. HENNET’s Secretariat provides the organizational and managerial support needed for implementing the network’s strategic plan.
