River Street Advisors, LLC

River Street Advisors, LLC provides discretionary portfolio management and financial planning to a mix of individual clients (including high‑net‑worth individuals), state and municipal agencies, charitable organizations, and corporations, managing roughly $539 million in client assets through a team of ten advisors and serving about 477 client relationships. The firm offers model portfolios, implementation using individual securities, mutual funds and ETFs, and may engage third‑party managers and software in delivering those services.

The firm documents investment plans in written investment policy statements and uses a combination of quantitative techniques (optimization and computer‑based risk/return analysis), fundamental and technical analysis, and third‑party performance and reporting tools to construct and monitor portfolios on a quarterly basis. River Street discloses the use of derivative strategies — including options for hedging, covered‑call writing, and monetizing or hedging concentrated stock positions — and may apply these strategies within separately managed accounts where appropriate.

Distinctive aspects noted in the brochure include that River Street is principally owned by Old Second National Bank and discloses affiliated referral arrangements and recommendations of affiliate services, which the firm identifies as potential conflicts of interest. The firm operates from five offices and, unlike many peer teams, its materials and marketing include presentation of performance information (including hypothetical results) and use of endorsements, alongside third‑party performance reporting.
