What MSS does

MSS Inc. (legally MSS, Inc., d/b/a MSS Engineering) is a privately held professional engineering consulting firm headquartered at 215 NW 4th Street in Corvallis, Oregon. Founded in 1972 by three Civil Engineering professors at Oregon State University, the firm was wholly acquired by John Seaders in 1980 and has operated continuously for over 50 years; following John Seaders' death in December 2021, the company continues under the leadership of his son Peter Seaders as President. The firm is independently owned, with no parent company, external investors, or private equity involvement disclosed.

The firm's offering is organized around four core service lines: Civil Engineering, Structural Engineering, Surveying, and Land Use Planning. Its technical stack consists of industry-standard engineering software and modern surveying equipment, including drone-based data capture that transfers field data into computer models for site analysis. The Land Use Planning service line, formalized on the website in 2023, extends the offering upstream into regulatory navigation, environmental assessment, and master planning. All four services are delivered as integrated, project-based engagements rather than standalone productized offerings.

MSS generates revenue exclusively through project-based professional services fees, with no publicly disclosed pricing tiers and no recurring or subscription model. Customer acquisition is sales-led and direct, relying on walk-in office visits, phone and email inquiries, and the company website, with growth driven primarily by regional reputation and referrals. The firm serves residential developers, commercial and industrial real estate clients, and public-sector entities across Oregon, Washington, and California, with historical work in Idaho and Alaska. Notable recent engagements include the Keizer Station Holiday Inn, Yaquina Industrial Park, Tyler Avenue Apartments ($16M construction), Tyler Avenue Townhomes, Northwest Freight ($5M construction), and the Cottage Grove Village Center subdivision. Marketing is minimal — a website, a LinkedIn page, and a Facebook page — consistent with a relationship-driven regional practice.
