Our Foundation

Built on what
matters most.

We believe that remarkable financial guidance begins with genuine trust — and that trust is built slowly, through consistency, candor, and putting your interests first. Always.

Honesty

We tell you what you need to hear, not what you want to hear. Straightforward advice and transparent fees.

Integrity

As a Registered Investment Advisor, we are held to a fiduciary standard. We are legally and ethically obligated to act in your best interest at all times.

Trust

We maintain personal, professional relationships with every client. You will always know who is managing your money and why every decision is made.

Client-First

Your goals drive every recommendation. We consider your objectives, risk tolerance, time horizon, tax situation, and personal circumstances before making any move.

What We Offer

Comprehensive Wealth Management Services,
deeply personal.

Investment Management

Customized portfolios aligned to your specific objectives, risk tolerance, and time horizon. We manage your assets with the same care we would apply to our own.

Financial Planning

Comprehensive planning using proven technology — cash flow analysis, retirement projections, and "what if" scenarios to help you achieve your long-term goals.

Retirement Planning

Strategies for accumulating wealth and creating sustainable income throughout your retirement years, structured around your unique lifestyle and legacy goals.

Tax-Aware Investing

Every investment decision considers the tax implications. We coordinate with your accountant to ensure your portfolio is structured for maximum after-tax efficiency.

Estate Considerations

We help you think through legacy planning, beneficiary designations, and wealth transfer strategies — coordinating with your estate attorney to protect what you've built.

Performance Reporting

Clear, transparent reporting so you always understand where you stand. No jargon, no hidden figures — just straightforward communication about your financial picture.

Who We Are

Two advisors.
One commitment.

Webster Street Investment Advisors is a two-principal firm, each partner bringing more than 30 years of investment experience to every client relationship. We are small by design — because genuine, concierge-level service requires it. When you work with us, you work with us, not an associate or call center.

Clients value Dave's clear communication, analytical mindset, and commitment to delivering fee-only guidance with the personal service of a boutique firm.

How We Work

A process built
around you.

Our approach is methodical, personal, and transparent. We do not believe in one-size-fits-all solutions — because your financial life is not one-size-fits-all.

01

Discovery

We listen first. We learn your goals, values, concerns, and circumstances before offering a single recommendation.

02

Analysis

We assess your complete financial picture — investment objectives, risk tolerance, time horizon, taxes, and legal considerations.

03

Strategy

We build a customized investment and financial plan aligned to your specific situation, not a generic model portfolio.

04

Ongoing Partnership

We monitor, report, and adapt continuously — and we are always reachable when life changes or questions arise.

Fee-Only. Fiduciary. Aligned With You.

We are compensated solely by our clients — never by commissions, product sales, or referral fees. As a Registered Investment Advisor, we are held to a fiduciary standard, legally obligated to act in your best interest at all times.
