About Liam T. Donovan
Liam is a cognitive optimization researcher and long term nootropics enthusiast with more than eight years of personal experimentation supported by scientific study. He started Greendoor after realizing that conventional approaches were incomplete and that ethical, thoughtful cognitive enhancement required more than basic search results.
