Lewis Irwin Landerholm

Founding Partner

Attorney Lewis LanderholmLewis Landerholm realized the importance of family and justice from a very young age. With grandparents in the legal field, a mother in education and a father who was a domestic violence counselor, Lewis was raised by a family dedicated to helping people. His role models taught Lewis that the world is a complicated place where education and a helping hand could make all the difference.

Dedicated to helping families through challenging times, Lewis founded Landerholm Family Law. He is known as a perceptive and compassionate lawyer who excels at helping those dealing with divorce and custody cases. Lewis handles the management of his firm, as well as a full caseload. His ability to be straightforward and understand both sides without personal bias has been crucial to the success of his practice.

Lewis began his law career as a part-time clerk for an attorney during law school, when he confirmed his passion for family law. Motivated to make his mark on the world, Lewis founded his practice right out of law school and continues to seek new, dynamic ways to foster positive change in the lives of his clients. He has eight years of upper management experience giving him business management skills that are integral to the continued success of his firm.

Lewis holds a bachelor’s degree in economics and a minor in business from University of Oregon. He received his juris doctor degree from Willamette University. Lewis is now the Board of Directors at Catalyst.

A self-proclaimed sports-addict, Lewis shows his team spirit both in the game and when he’s cheering on the sidelines. He supports a team of dedicated attorneys, encouraging their professional growth and development. His positive thinking keeps him motivated, solution-oriented and makes him an ideal mentor and leader for his team.
