Katherine GrayBuck
Pastor & Hospital Chaplain

Katherine GrayBuck is an Associate Pastor at Church of the Apostles. She is also called as a professional Spiritual Care Provider, or Chaplain, at Harborview Medical Center and serves on the Palliative Care Team and as a faculty member of the Palliative Care Fellowship.

Her grounding as a Pastor is rooted in the practice of deep listening and empathy. Her particular ministry leanings are feminist, LGBTQIA+ inclusive, and engaging in anti-racism work.

He attended Yale Divinity School and Pacific Lutheran Theological Seminary and was then called and ordained as pastor at Church of the Apostles in 2012 where he continues to make a fool of himself in front of people in new and innovative ways.

He works as a developmental consultant for churches and, as an administrator of the Intercultural Development Inventory, works with individuals and organizations on cultural competency and communication.
