William Blair’s Private Wealth Management division provides discretionary and non‑discretionary investment management, financial planning and wealth services to individuals (including high‑net‑worth clients), foundations, pension and corporate clients. The firm also sponsors a wrap fee program, supports platform and sub‑advisory arrangements, and distributes affiliated pooled products while operating as an SEC‑registered investment adviser and broker‑dealer. The firm pursues active, research‑driven management across equities, fixed income and alternative strategies, offering proprietary home‑office models and model portfolios to advisory clients and to other registered investment advisers through a Non‑Discretionary Model Portfolio Program. PWM advisors may hire third‑party Sub‑Managers through platform providers or engage the affiliate William Blair Investment Management LLC (WBIM) as a sub‑adviser, and William Blair provides access to private funds and co‑investment opportunities via its MB Investments Program. Notable features in the brochure include the firm’s scale — roughly $64 billion in reported AUM and a reported 322 advisors, implying approximately $200 million of AUM per advisor — and an in‑house MB Investments structure where clients must affirmatively elect participation and where an affiliate (the MB General Partner) performs valuation and may receive carried interest. The brochure also details integrated operational relationships with custodial/clearing and platform providers (including NFS) and affiliated product conduits (WBIM, affiliated mutual funds and private funds), which influence product access, allocation and certain fee and credit arrangements.

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.
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.
