Mason County Business: OneStop Northwest Opens Shelton Showroom as North Mason Ports Eye $2M Joint Investment on SR-3

Mason County’s economic picture this spring runs from downtown Shelton to the shores of Hood Canal. A minority-owned branding and marketing firm is opening its first showroom in the county seat, and two north Mason port districts are exploring a $2 million joint investment on State Route 3 that could anchor commercial activity in the Allyn-Grapeview corridor for decades.

OneStop Northwest Opens Downtown Shelton Showroom — Grand Opening May 22

OneStop Northwest LLC, a Union-based company with more than 20 years in business, hosts its grand opening celebration at 124 N. 2nd St., Suite A in Shelton on Friday, May 22, 2026, from 4:30 to 7:00 p.m. The event is free to attend, with tours of the new showroom, a ribbon-cutting ceremony, introductions to the team, light refreshments, and prize giveaways. Attendees are asked to RSVP in advance at onestopnw.com.

The company positions itself as a “360° Brand Management” partner for businesses across Mason County. That means a single vendor for promotional products and branded apparel, commercial printing, custom company stores, website development, SEO and social media marketing, digital marketing, IT support, payroll automation, and government contracting for internet and phone services. For a small business juggling multiple vendors for these functions, that consolidation has real operational value.

OneStop Northwest is a member of the Shelton-Mason County Chamber of Commerce. The new downtown Shelton address — visible and central in the county seat — marks a meaningful step out from its Union roots and into the county’s commercial center. Businesses in Shelton, Belfair, Allyn, Hoodsport, Matlock, and any community in Mason County now have a local resource for professional branding and business technology without leaving the county.

Ports of Allyn and Grapeview Eye $2 Million SR-3 Property Together

Forty miles north and east of downtown Shelton, on State Route 3 near East Harding Hill Road, a commercial and light industrial property is drawing interest from two of north Mason County’s smallest public agencies. Port of Allyn Executive Director Travis Merrill raised the opportunity with Port of Grapeview Commissioner Mike Blaisdell, and at the Port of Grapeview’s April regular meeting, commissioners agreed the property warranted a closer look.

The property carries an assessed value of approximately $2 million. Built by a family from Stretch Island, it has a history of commercial and light industrial use. Currently some of the building is occupied by tenants; part of it sits vacant with room for future expansion.

The financial case is modest but meaningful for small ports. Merrill estimated that after expenses, each port district could earn $15,000 to $18,000 per year from the property through leasing and rental income.

“That alone is something that puts us on better footing,” Merrill said.

Port of Grapeview Commissioner Doug Jones acknowledged the price tag is significant but agreed it was worth a site visit. “It’s something we should at least talk about,” Jones said. Port of Grapeview Managing Official Amanda Montgomery agreed to research how other port districts have structured shared asset ownership arrangements.

Merrill was candid about why the search for new revenue matters. “There is no way that either of our ports, or even any of the ports in Mason County except the Port of Shelton, is going to be able to weather the storm that seems to be coming without some sort of financial assets,” he said during the April meeting.

The Port of Allyn came into 2026 on solid footing by other measures — receiving a clean state accountability audit with no findings, and recouping $99,731 in full from Washington State’s DNR Derelict Vessels Program after removing the sunken vessel Sea Bear from Hood Canal waters.

The SR-3 site represents something bigger than a balance sheet line. Industrial development is part of any port district’s core statutory purpose under Washington state law, and a jointly owned commercial asset on SR-3 could anchor the kind of business activity in the Allyn-Grapeview corridor that has been slow to materialize even as residential growth in north Mason County has accelerated.

What This Means for Mason County

Both stories, at opposite ends of the county, represent the same underlying trend: local economic actors are investing in infrastructure — showrooms, shared assets, consolidated services — rather than waiting for outside capital to arrive.

Mason County’s small ports and small businesses face genuine financial headwinds, from inflation to limited revenue streams to the rising cost of insurance and operations. Moves like the OneStop showroom and the SR-3 property discussion reflect a community building its own commercial depth.

For residents in downtown Shelton, the OneStop Northwest grand opening on May 22 is a free community event worth attending. For residents in the Allyn-Grapeview corridor, the Port of Allyn and Port of Grapeview hold regular public meetings open to the community — the SR-3 decision process will play out in those rooms over the coming months.
