Keseena sits down with Calvin Sun, an ER physician, author, world‑traveler, cancer survivor, and former Manhattan Borough President candidate (June 2025). Recorded before the election, they explore what emergency medicine taught him, how he discovered a kidney tumor and survived it, why travel is both enriching and important, and what led him to step into public service. Calvin shares vulnerability, vision, and a deep commitment to service - no matter the outcome.
