About Lewis Irwin
Lewis Irwin Landerholm founded his own practice in 2010. He has spent the last decade and a half building a practice that blends counseling and advocacy. Colleagues describe him as deliberate and practical in his approach to legal problems.
He began his academic journey at the University of Oregon, where he earned a Bachelor of Science. He then attended Willamette University College of Law and received his Juris Doctor. The combination of a public university undergraduate education and a regional law school shaped a pragmatic view of the law and client service.
After law school Landerholm entered private practice and within a few years launched Landerholm Law. He is listed as the firm’s founding lawyer, a role he has held since 2010. That experience required managing both the legal work and the business side of running a small firm. He learned to balance case strategy with client communication and office administration.
His office affiliations include Pacific Cascade Legal. He maintains ties to that office while overseeing work produced through Landerholm Law. The arrangement allows him to draw on shared resources while keeping the firm’s case handling under a central umbrella.
People who have worked with him note a steady, methodical style. He handles intake, evaluates options, and follows cases through to resolution. He has handled both advisory work and matters that required formal proceedings. He tends to favor clear explanations and practical next steps when advising clients.
Outside of day-to-day casework he has overseen firm operations and handled the business tasks that come with founding a practice. That background gives him insight into the expectations of small and mid-sized clients who need counsel that understands both legal and commercial concerns.
As of 2026 Landerholm practices through Pacific Cascade Legal while maintaining Landerholm Law, concentrating his efforts on client counseling and casework handled through those offices.
