## About

Windsor Capital Management launched in 2000 when John O. Harrington established the registered investment advisor in Phoenix, Arizona. The firm provides portfolio management, retirement planning, and sub-advisory services to a client base that includes high-net-worth individuals, families, and assorted business entities. Harrington structured Windsor as a fee-based advisory practice rather than a brokerage, placing fiduciary obligation at the center of the engagement model. The firm's investment approach rests on constructing tailored portfolios across equities, fixed income, and alternative allocations. Windsor operates as a discretionary manager, selecting individual securities and third-party funds rather than running pooled vehicles of its own. The practice spans asset allocation design, manager due diligence, and ongoing monitoring for retirement accounts, trusts, and corporate cash management mandates. Geographic focus remains predominantly domestic US markets, though the firm evaluates international exposures where client objectives warrant. As a privately held RIA based in Phoenix, Windsor Capital Management maintains a deliberately lean footprint consistent with many independent advisory shops in the Southwest. The firm reports no separate institutional vehicles, no commingled funds, and no public philanthropic foundation adjacent to its advisory business. Team size, total assets under advisement, and specific client concentration figures remain undisclosed in the firm's regulatory filings and public communications. The firm's structural differentiator is its fiduciary-only posture within the fragmented US wealth management landscape. Unlike wirehouse-affiliated advisory teams or broker-dealer platforms, Windsor operates as a standalone RIA where investment recommendations are legally obligated to serve client interests. This architecture attracts mandates from families and businesses seeking a separation between advice and product distribution.

## Questions

### How does Windsor Capital Management charge for its services?

As a registered investment advisor, Windsor charges asset-based fees on discretionary portfolios, aligning compensation with account performance rather than transaction volume. The firm's Form ADV filings describe this fee-only approach as standard for the client relationships it maintains, though precise fee schedules remain negotiated privately with each mandate.

### Does Windsor Capital Management operate any proprietary investment funds?

No. Windsor does not manage commingled vehicles, hedge fund structures, or private equity pools. The firm constructs portfolios using individual securities and third-party mutual funds or ETFs, positioning itself as an allocator and portfolio designer rather than an asset manager distributing proprietary products.

### Does Windsor Capital Management disclose its assets under management?

The firm does not publicize a current AUM figure through its regulatory filings or website. Many independent RIAs below the $100 million threshold report assets under management as a range rather than a specific number, and Windsor's public disclosures have not broken from that practice.
