About

Cornerstone Professional Advisor Services serves individual and high‑net‑worth clients as well as pension and profit‑sharing plans, business entities, trusts, estates and charitable organizations, offering discretionary portfolio management and financial planning on request. The firm also serves as a retirement‑plan co‑fiduciary for certain clients and implements strategies through third‑party advisory programs and separately managed account platforms.

CPAS’ investment approach is rooted in modern portfolio theory, favoring diversified allocations implemented principally through passive mutual funds and ETFs and a buy‑and‑hold time horizon (generally five to ten years or longer). The firm commonly uses third‑party platforms (including SEI) for custody, SMA strategies and automated quarterly rebalancing, and it assesses third‑party managers against client objectives when making selections.

What is notable about CPAS relative to many peers is its material affiliations outside pure investment advice: the firm is affiliated with a certified public accounting firm, Madonna & Co., in which certain firm members hold ownership interests and may receive distributions, and several principals are licensed insurance agents who may introduce clients to insurance products and receive commissions. These tied relationships, along with the firm’s ability to implement recommendations through affiliated broker‑dealer channels and its disclosed insurance‑related revenue, are highlighted in the brochure as potential conflicts that the firm discloses to clients.

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.
