At Marvin Chorzempa & Larson, we work with our clients as a team. We recognize that, despite our experience, our clients bring special knowledge to the table and are an essential part of our advocacy.

Our attorneys are dedicated to providing the highest level of legal representation to our clients and to serving our community. To facilitate this, all of the firm’s attorneys participate in continuing education classes, professional organizations, and are active in our community. While our firm primarily engages in construction defect litigation, arbitration, and mediation, we also assist clients in legal risk management, business formation and contract drafting and negotiation.

At Marvin Chorzempa & Larson, we take our role in the overall design community very seriously. We view ourselves not only as advocates to our actual clients, but also counselors to the community as a whole. In furtherance of this goal, we regularly participate and support both the AIA Portland Chapter and ACEC Oregon. We have advised these groups on legislative matters, presented seminars on legal issues and sponsored events.
