About

Tumwater Wealth Management provides ongoing portfolio management, comprehensive financial planning, and pension consulting to a mix of individual and institutional clients, including pension and profit-sharing plans, charitable organizations, and business entities. The firm reports managing roughly $407 million across about 284 client accounts and operates with a two-advisor team that handles discretionary portfolio decisions on behalf of clients.

The firm’s investment process is long-term and buy-and-hold oriented and draws on modern portfolio theory, fundamental analysis, cyclical analysis, and quantitative methods to construct and rebalance customized allocations. Portfolios are tailored to clients’ goals, time horizons, and risk tolerances and may include mutual funds, ETFs (including precious metal ETFs), real estate funds/REITs, fixed income including TIPS, and insurance-based products such as annuities.

What is distinctive about Tumwater is the combination of a compact advisory team managing an unusually large asset base per advisor and an explicit pension-consulting capability that includes benchmarking, fiduciary plan reviews, and participant education. The brochure also notes use of multiple custodial relationships for retirement plans (including Schwab Institutional and Interactive Brokers) and a practice of integrating financial planning into ongoing portfolio management, which can be atypical for firms of this size.

Warmer provides personalized recommendations and introductions to independent fiduciary advisors. We do not supervise advisors, manage or hold assets, guarantee performance, or provide advice about specific investments.

Each advisor listed on our site is an independent fiduciary responsible for their own advice. Warmer may receive fees from advisors for participation or referrals; these fees are paid by advisors and do not affect the fees clients pay for advisory services.

For advisor listings, we rely on sources including public filings and data provided by advisors, and we cannot guarantee that all information is current or accurate. Please review an advisor's Form ADV and do your own diligence before entering into an advisory relationship.
