ECM

Elgethun Capital Management was founded in 2003 by Terry Elgethun. John Barker partnered with the firm in 2011 and purchased it outright in 2012. Barker now serves as President and Owner while directing investment strategy and client relationships. ECM allocates client capital across five primary asset classes: public and private equity, commercial and residential real estate, and municipal and corporate fixed income. It avoids commodities and currencies. The firm executes through direct holdings in individual securities, mutual funds, and alternative vehicles including private credit and venture capital. It maintains exposure across North America, Europe, Asia, and additional regions. Investment stages include seed, early, and growth opportunities. The firm reports 15 investment and advisory professionals. It added Chad D. Hatch as Strategic Advisor in 2025 and Christian Schoppert as Private Capital Associate in 2025. ECM maintains relationships with custodians including Charles Schwab Institutional, Pershing, and Fidelity. It sponsors the Prairie Family Business Association and holds membership in the Greater Sioux Falls Chamber of Commerce. ECM operates as an independent SEC-registered RIA rather than a captive bank or brokerage affiliate. This structure removes proprietary product conflicts and allows the firm to serve both single-family and multi-family clients under a single fiduciary mandate.
