Firm profile

Overview

Mills Barrington Advisors, LLC is a small, fee-based registered investment adviser that manages discretionary portfolios primarily for individual and family clients and small businesses. The firm’s portfolio work centers on exchange-traded equities and ETFs as the core building blocks of client accounts, supplemented by mutual fund sleeves and targeted allocations to third‑party hedge funds for alternative exposure. Fee billing is a percentage of assets under management, and the adviser does not position itself as an ESG-focused manager. Investment posture appears to prioritize liquid, public-market instruments—individual equities and ETFs—while using external alternative managers where clients need diversification or uncorrelated returns. Portfolios are custodied at Interactive Brokers, which aligns with a model that favors low-cost execution and direct-market access for equity and ETF strategies.
