About the author
Martin Vendemia has published many books, audio programs, and written works over the decades — on life, relationships, self-improvement and self-development, and the use of language and influence. The Grand Matriarchy is his first book on family dynamics, social structure, and the forces reshaping how families function.
Drawing on research, evolutionary science, international family systems, and lived community experience, the series examines what has been lost in the modern West, where the grandmother-centered family still thrives around the world, and what can be deliberately rebuilt.
Inner Group Media is the publishing imprint that carries his books. The Grand Matriarchy community he built lives on in the GMA Daisy world of sites and content.
