William Hamilton

I’m a husband, writer, musician, and business owner.

I live in Tampa with my wife, Rayssa. I’m a member of Calvary Church, where I teach the Bible weekly as a layman.

Title card for the video What Is Actually Happening in Brazil, with Lula and Jair Bolsonaro

What is actually happening in Brazil.

Brazil voted on October 4 and votes again on October 25. In fourteen minutes I tell the story most Americans have not heard: how the Supreme Court freed Lula, what it did to his opponents, and what this election could change for the church there.

At home in Tampa.

Rayssa and I married on the beach in February 2025 and live in Tampa, Florida.

I’m a faithful member of Calvary Church, where I teach the Bible weekly as a layman. My Christian faith is central to my marriage, teaching, and writing. Valley grew out of game nights and Bible studies in my living room.

I started making videos before I started a business: weddings, music videos, church events, and trips with friends. In 2020, I came up with Hamilton Studios, which became my first LLC and eventually ServiceLine Pro. Today I also own Westchase Painting Company and run Church Posting with my father, Scott.

Thirty Summers

I wrote this song for Rayssa. The music video takes its watercolor and scrapbook style from the scrapbooks she keeps.

Teaching & preaching.

Calvary Church ↗

I teach the Bible weekly as a layman at Calvary Church, where I’m a member. I also take part in Valley’s occasional online Bible studies. My recordings include Wednesday-night teaching at Calvary, messages from Valley, and guest preaching. Voices from the Valley carries these recordings alongside messages from other teachers.
