Africa Caribbean Heritage Alliance (ACHA) is the organization that reunites Africa and the Caribbean in the areas of heritage, culture, economy, education and travel. Started by Okama Ekpe Brook, who has worked for the United Nations in different parts of the world, ACHA is uniquely based in the hub of the Caribbean, St. Maarten and Nigeria, Africa. Okama, originally Nigerian, fell in love with St. Maarten and the Caribbean, having lived and worked in a number of the islands. Her background working in nation building has uniquely given her a perspective on the relationships between Africa and the Caribbean that can be strengthened and nurtured.
