Armstrong, Fleming & Moore

Armstrong, Fleming & Moore

Armstrong, Fleming & Moore opened its doors in 1983 as an early entrant into the then-nascent financial planning industry. Co-founders Alexandra Armstrong and Mary Moore built the practice on fee-based planning for professionals in the Washington, D.C. area. Today the firm operates as a registered investment advisor, with second-generation advisor Ryan Fleming, CFP®, and Mary L. Moore, CFP®, still actively managing client relationships from the firm's sole office at 1800 M Street NW. The firm constructs individualized portfolios across equities, fixed income, and managed accounts for clients concentrated around retirement transitions. The team of 20 — more than half of whom hold the CFP® designation — focuses on tax-aware distribution strategies and long-term capital preservation rather than opportunistic deployment. Armstrong, Fleming & Moore does not publicly disclose its third-party manager roster or custody relationships, consistent with its posture as a private advisory shop serving a local client base. The 20-person team includes 13 professionals listed on the firm's website, 11 of whom carry the CFP® mark. All staff work from the single Washington, D.C. office. The firm runs a concurrent philanthropic practice that integrates charitable planning into its core advisory work, though it does not operate a separate foundation. No recent fund closings, GP stakes, or co-investment structures are publicly recorded. Armstrong, Fleming & Moore's structural difference is negative: it is a true fee-only RIA, not a broker-dealer hybrid, and has remained deliberately single-office and single-city for over four decades. That architecture eliminates the conflict-of-interest disclosure burden that larger hybrid firms carry and anchors the firm's credibility with a concentrated book of D.C.-area retirees who value longevity of relationship over geographic breadth.
