&Partners

&Partners

&Partners opened in 2023 in Nashville, Tennessee, founded by Cynthia Marsteller and Ellen Marsteller under the conviction that advisor-owned firms produce better client outcomes than the traditional brokerage structure. The firm operates as a registered investment advisor, and its first branded office, Marsteller Wealth, reflects the family practice at its core. Cynthia brings client advisory experience, while Ellen contributes an institutional investment background, together designing a service model that blends personal financial planning with access to alternative investments and emerging strategies. The firm delivers financial planning and discretionary portfolio management across public markets and alternative investments. Its investment leadership includes Partner Fredrik Axsater, a former portfolio manager at BlackRock, head of defined contribution at State Street Global Advisors, and CEO of LGM, the BMO-owned emerging-market equity boutique. Axsater works directly with the Marsteller team on portfolio strategy and investment selection. The Marsteller Wealth office explicitly markets alternative investments as a component of its advisory platform, aiming to give individual clients access to asset classes more commonly reserved for institutional investors. The firm's geographic footprint spans the US and the United Kingdom, with Axsater based in London. &Partners operates with a deliberately flat operational structure. Advisors receive a dedicated operational point of contact and a "concierge CIO" resource, a design choice that removes the layered management typical of larger wealth management firms. The firm discloses no standalone AUM or total deployment figure. Fredrik Axsater operates as a third-party consultant affiliated with the firm, not as a direct employee — an arrangement the firm discloses on the Marsteller Wealth team page. In 2023, the firm formally integrated Marsteller Wealth as its initial advisory unit, establishing the partnership model from day one. Structurally, &Partners is an RIA that functions as a multi-family office gateway for its client base but organizes its economics around internal advisor equity rather than external shareholders or a parent bank. That partnership structure is the firm's architectural differentiator — advisors are owners, not employees, which the firm argues removes the conflict between management's profit motives and client outcomes. The London-based investment consulting arrangement adds a cross-border capability unusual for a Nashville-headquartered firm of its vintage.
