Our History

Our Story: A New Firm, Longtime Albany Attorneys

Our firm's story begins with a simple truth: there's something special about practicing law in the community where you belong. Miller Castleton & Flinn was formed in 2026 by three partners who have built their careers here — Sarah Castleton and Mike Flinn have each practiced law in Albany since 1995. The firm is new. The people, the office, and the commitment to this community are not.

Daniel W. Miller has practiced in Linn and Benton counties since 2014. He began his career with a Corvallis firm in local government law and served as city prosecutor for multiple Mid-Valley municipalities before turning his focus to family law — bringing a working understanding of both sides of the courtroom to every case he handles.

Sarah Castleton brings more than 30 years of service to the Albany area in estate planning, probate, guardianship, and trust administration. She serves on the board of the Albany Safety Foundation, and her practice reflects the same instinct that drives that work — a genuine desire to help people protect what matters most.

Mike Flinn is one of the most seasoned criminal defense attorneys in the Mid-Valley, with nearly three decades in Oregon courtrooms. Alongside his defense practice, he handles personal injury and DUI matters, bringing the same tenacious advocacy to every client.

Together we've built something different here—a firm that combines serious legal expertise with genuine community connection. When you walk into our historic downtown Albany office, you're not entering a corporate law machine. You're meeting neighbors who happen to be attorneys.
