About

Five Mile River serves families, high‑net‑worth individuals and retirement accounts with discretionary portfolio management and related advisory services. The firm manages about $86.5 million for roughly 100 client accounts and generally requires a minimum relationship size, with assets managed by a small team of three managing directors.

The firm follows a bottom‑up, fundamentally driven, value‑oriented investment process that seeks companies trading below private‑market value where a catalyst may close the discount, implementing income, balanced and growth strategies. Client portfolios are typically concentrated (about 30–35 holdings), are 80–100% equity when fully invested, target low turnover (25–50% annually) and employ formal sell disciplines and risk controls.

Notable features include 100% employee ownership with an explicit ownership split among the founding partners (50% / 25.5% / 24.5%), management of only discretionary assets (no non‑discretionary mandates), and governance practices that include a written code of ethics and no disciplinary history. The firm recently added a managing director with prior experience as a chief investment strategist who helped scale an RIA to over $2 billion, reflecting an emphasis on supporting multigenerational family relationships and expanding second‑generation wealth management.
