Mynor grew up in Granger, Washington and received a B.A. in History from Washington State University. After graduating he worked for the state government and non-profits advocating for communities of color through legislation and community programs. Currently, Mynor is a second-year law student at Seattle University. This previous summer he worked as a Calhoun Family Fellow under Bob Boruchowitz. This fellowship focused on racial justice and public defense work and the fellows worked on projects regarding ending sex offender registration for juveniles, advocating for reparations for Black people in the state of Washington, and advocating for police reform. Mynor hopes to use his legal degree to help support Black and Indigenous people and people of color through systemic advocacy.
