Westport, CT Riverside Avenue Office

Mercer Global Advisors serves individuals and families as well as small business owners, plan sponsors, foundations, non-profits, and endowments, providing discretionary and non-discretionary investment advisory services alongside financial, tax, retirement and estate planning and family office services. The firm delivers retirement plan consulting, charitable and non-profit advisory, and other specialized services through client agreements and custodial/clearing arrangements.

The firm’s investment approach is grounded in Modern Portfolio Theory and emphasizes globally diversified, risk-appropriate portfolios with multi-factor tilts and regular rebalancing. Portfolios are implemented using a mix of low-cost ETFs and index funds, separate account managers, direct indexing, and, where suitable, interval and private funds via platforms such as Orion; Mercer also offers packaged programs (Market Series, Multifactor Series, Income Series) and tax-management options.

Mercer publishes client education content and audio programming (podcasts) and runs firm-wide events and initiatives (for example, an InvestHERs summit sponsored by Dimensional Fund Advisors and internal Academies/National Symposiums), a capability that is less common among large enterprise advisers. The firm also integrates affiliated service lines and platforms — including Mercer Advisors Tax Services (MATS), Mercer Advisors Private Asset Management and the Aspen Partners private‑fund platform, affiliated insurance and broker‑dealer entities, an attorney‑led estate planning option (ASLG), and a Wellthy caregiving concierge offering for qualifying clients — and runs an active acquisition strategy to onboard advisor teams and legacy client programs.
