About

Tremont Street Advisors, LLC provides fee-based investment management to individuals, high‑net‑worth clients, and business owners, offering discretionary and non‑discretionary portfolio management, third‑party manager arrangements, and retirement plan advisory services. The firm also provides ERISA plan support (including limited‑scope 3(21) fiduciary assistance), participant education, and uses SEI/SIMC program implementations for certain client accounts.

The firm combines multiple methods of analysis — fundamental, technical, cyclical and economic — and implements long‑ and short‑term strategies and strategic asset allocation tailored to documented client objectives and risk tolerances. It implements advice through direct management, SEI/SIMC model/managed‑account programs, or third‑party sub‑advisors while retaining overall responsibility for the client relationship and disclosing solicitor or sub‑advisor arrangements.

Distinctive features include an affiliation with accounting professionals: a firm principal maintains an active CPA practice with an external accounting firm, and other representatives offer insurance, tax‑preparation, or accounting services, arrangements the brochure discloses and manages as potential conflicts. The firm also recently documented use of Standing Letters of Authorization for client transfers and emphasizes ERISA 3(21) plan services — operational and cross‑professional elements that are less common among comparable team firms.

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.
