Four years ago, I approached Siobhan to take a chance with me at Medium to build something new, exciting and hard, with no guarantees for success. I was incredibly honored when she said yes. Since then she has built a world-class editorial team and has made Medium a better place every day with her presence, impact, and integrity. She has decided this time of transition is her time to move on. Together, we’re confident in the new direction and that we have the right people in place to lead the department for the next chapter. Siobhan’s last day is being finalized as she works to set up the editorial team for success.
