Welcome to Trinity Consultants Washington

The Soundview Consultants team in Gig Harbor and Mount Vernon specializes in natural and aquatic resource consulting services. The team employs a solution-oriented and excellence-driven approach that carefully considers clients’ needs while balancing the complexity of the environmental regulatory environment. With an in-depth knowledge of federal, state, and local environmental regulations and permitting processes across the Pacific Northwest, we have a deep track record of successful project outcomes in many industries.

Trinity’s Seattle staff bring extensive hands-on experience with environmental permitting and compliance in the Pacific Northwest. Since 1996, the Seattle office has served Washington and Alaska clients on more than 3,000 projects in a wide range of industries. With an in-depth knowledge of the state, local, and federal permitting and compliance processes, we support industrial clients with authorizing capital projects and environmental compliance.

Your facility in Washington deserves a tailored approach—not a one-size-fits-all checklist. Trinity’s regional consulting team understands the specific air, water, waste, safety, and permitting challenges you face right here in Seattle and across the state.

Trinity’s WestLand team supports Spokane with water & ecology services.
