About
McMillen & Company provides discretionary capital management and ongoing portfolio oversight for individuals (including high‑net‑worth clients), charitable organizations, and business entities. Services include customized portfolio construction using individual stocks and bonds, exchange‑traded funds, mutual funds, and access to third‑party sub‑advisors.
The firm tailors allocations to each client’s stated objectives and risk tolerance, drawing on public filings, third‑party research and rating services, and conducts reviews at least annually with rebalancing when client circumstances or market values change. McMillen & Company typically operates under discretionary authority, may aggregate trades across accounts, and describes its strategies as oriented toward capturing market rates of return while acknowledging the risks of loss and potential for frequent trading when appropriate.
Distinctive features include a small client roster relative to assets under management—managing approximately $111 million for about 32 clients—resulting in a notably high assets‑per‑client profile and a concentrated, relationship‑focused practice. The firm is founder‑led, discloses no disciplinary history, does not charge performance‑based fees or sponsor wrap programs, and explicitly offers a discount to nonprofit clients while retaining the discretion to decline smaller portfolios.

Not sure where to start?
We'll help you think it through—whether you ultimately need an advisor or not. Warmer helps you compare advisors clearly, so you can choose with confidence.
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 introductions are provided by FinanceHQ LLC (“FHQ”), a wholly-owned subsidiary of Warmer and an SEC-registered investment advisor. We receive compensation from certain participating advisors for introductions or referrals. This creates a conflict of interest because we have an incentive to recommend advisors who compensate us, including those who pay us more. You pay no fee to use our matching service, and advisor fees are not increased because of a referral or introduction. We do not review the ongoing performance of advisors, manage or hold assets, guarantee performance, or provide advice about specific investments.
By using our service, you agree to our Terms of Service and Advisory Agreement, and acknowledge our Privacy Policy. Please review FHQ’s ADV Part 2A and Form CRS. Logos provided by Logo.dev
