Meet the attorney who'll handle your case

Chris Clark, Sole Attorney at The O'Neill Law Firm

Chris is the only attorney at the firm, which means the person you talk to on the first call is the person who drafts your documents, files your petition, and answers your questions two years from now.

Continuing the Practice John O'Neill Built

Chris Clark took over The O'Neill Law Firm from his late mentor, John O'Neill. John built a practice on being reachable and on treating a probate or an estate plan as something happening to a family rather than a file, and that's the practice Chris has kept.


Continuing this practice it means keeping it small on purpose. There's no legal assistant in between, no case handed off when he's busy, and no version of this where you call and reach someone who has to look your name up. For probate and estate planning, where the questions are often personal and rarely convenient, that structure is the whole point.

Attorney Chris Clark brings years of experience, professional excellence, and a passion for helping Portland-area families protect what matters most.

Chris has also presented this material outside the office, in presentations to local businesses and community groups, because most of what makes estate planning intimidating is vocabulary rather than substance. That's the same standard he holds himself to in a consultation: if he can't explain why a document matters in language you'd use yourself, he hasn't finished the job.


Probate and trust administration is a large part of Chris’practice. If that's why you're here, the probate and trust administration page covers Oregon timelines, costs, and what the personal representative role actually requires.
