Dr. Roy Casagranda Podcast
The Dr. Roy Casagranda Podcast is dedicated to unerasing the erased peoples of the world. Too often, history is written by the powerful, leaving entire communities, cultures, and truths out of the dominant narrative. This show seeks to tell those stories. Through these conversations, Dr. Roy digs for the truth, weeds out misinformation, and challenges conventional wisdom. The conversations span politics, world history, philosophy, and culture, always with an eye toward justice and a deeper understanding of where we've been, where we are, and where we are heading.
