About

Oak Street Advisory Group, LLC provides personalized investment advisory services to individual and high-net-worth clients, offering financial planning, consulting, and both discretionary and non-discretionary portfolio management. Engagements typically begin with a complimentary initial consultation and result in a written financial plan or an ongoing management relationship with continuous portfolio supervision.

The firm’s investment process combines fundamental analysis with principles of modern portfolio theory to build diversified portfolios using mutual funds and ETFs, and it performs formal account reviews at least annually. It offers planning on an hourly or retainer basis, manages account custody through recommended custodians, and evaluates retirement-rollover decisions by comparing plan features, fees, and tax considerations.

What is uncommon for a firm of this size is the inclusion of educational seminars and workshops for clients and prospects, indicating an emphasis on group education in addition to individual advice. The brochure also reflects a relatively large assets-under-management level supported by a small advisory team and a practice that accepts clients without a formal account minimum, and the firm does not participate in wrap fee programs.

Find your advisor

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. Advisors are independent and may not have reviewed or updated this information. Please review an advisor's Form ADV and do your own diligence before deciding whether to work with them.

Advisor matching and referrals are provided by FinanceHQ LLC ("FHQ"), a wholly-owned subsidiary of Warmer and an SEC-registered investment adviser. We may be compensated by participating advisors. You pay no fee to use our matching service, and advisor fees are not increased because of a referral. We do not supervise advisors, manage or hold assets, guarantee performance, or provide advice about specific investments.

By using our service, you agree to the Warmer Terms of Service and FHQ Advisory Agreement, and acknowledge Warmer's Privacy Policy. Please review FHQ's ADV Part 2A and Form CRS. Logos provided by Logo.dev
