Jon K. Brennan
November 17, 1970 – October 9, 2026

Jon K. Brennan, 55, passed away following a courageous battle with cancer.

For nearly 30 years, Jon served his community as an EMT, helping people through some of the most frightening moments of their lives. Exceptionally intelligent, compassionate, and wonderfully irreverent, he was known for his quick wit, remarkable memory, and infectious laughter.

A devoted Seahawks fan, Jon shared over three decades of season tickets with his lifelong best friend, Nick. He loved reggae music, Halloween, orangutans, and all things Irish and Celtic.

Jon cherished his frequent visits to Arizona with his sister, Shelley, and brother-in-law, Tom, sharing adventures, laughter, and peaceful evenings beneath the stars.

In accordance with his wishes, Jon’s final resting place will be Giant’s Causeway in Northern Ireland.

He will be deeply missed and forever loved.
