AMERITRUST INVESTMENT ADVISORS
Ameritrust Investment Advisors was founded in Tulsa in 1981 by a group of local banking and legal professionals, with Michael L. Bourne assuming leadership early on. The firm grew out of a traditional trust-and-estate practice, gradually accumulating a group of unrelated families who consolidated their investment management under one roof — making it a genuinely early example of a multi-family office, decades before the term became an industry category. The firm structures itself around private credit origination and direct real estate equity, layered with manager-selected public market portfolios for core liquidity needs. Its primary deployment mechanism is origination of senior and mezzanine debt secured by Oklahoma and Texas commercial real estate — including medical office, industrial, and single-tenant net-leased assets — often sourced through local banking relationships rather than broker-led auctions. On the equity side, Ameritrust acquires stabilized multifamily and necessity-based retail centers in secondary markets across the Sunbelt. Publicly traded securities allocations are typically implemented via separately managed accounts and pooled funds selected by the internal investment committee, rather than proprietary fund-of-funds vehicles. Operations center on a Tulsa headquarters with a secondary presence in Oklahoma City. Senior Vice President Jake Dollarhide joined in the late 1990s and has taken an increasingly visible external-facing role, particularly in regional media, where he contributes to energy-sector and macroeconomic commentary that frequently touches on the firm's credit-market views. The firm has not disclosed a total deployment or headcount figure. No separate philanthropic foundation or operating business has been publicly linked to the entity. What distinguishes Ameritrust structurally is its role as an off-market, relationship-driven direct lender to borrowers who fall between the credit appetites of Oklahoma's community banks and the deal minimums of national private-debt funds — a niche that exists precisely because of the firm's embeddedness in local professional networks. Succession appears to rest on a slow transition from Bourne to Dollarhide and a small cohort of senior advisors, though no formal public timeline has been announced.

Frequently asked questions
Who runs investment decisions at Ameritrust Investment Advisors?
Michael L. Bourne, as President and CEO, leads the firm with final authority on investment decisions. Senior Vice President Jake Dollarhide also participates in the investment committee and frequently represents the firm's credit-market views publicly. Specific allocations are determined by a small internal committee rather than a single CIO model.
Is Ameritrust structured as a single family office or does it operate more like a boutique asset manager?
Ameritrust functions as a multi-family office serving multiple unrelated families. Its investment arm operates with the direct-origination posture of a boutique private debt manager, but the client relationships and service model are rooted in consolidated family-office reporting and estate planning coordination, not pooled fund marketing.
Does Ameritrust participate in fund commitments or only direct deals?
Ameritrust primarily originates direct private credit and real estate equity investments in the South Central U.S. For public market exposure, the firm allocates to external managers via separately managed accounts and selected pooled vehicles. It does not market a proprietary fund-of-funds, and direct private deals constitute the core of its strategy.
What real estate asset classes does Ameritrust target?
The firm focuses on income-producing commercial real estate in Oklahoma, Texas, and adjacent Sunbelt markets. Documented preferences include medical office buildings, industrial properties, and single-tenant net-leased retail, acquired through direct negotiation with local developers and owners rather than broadly marketed processes.
What is Ameritrust's known posture on co-investments alongside external GPs?
Public disclosures do not detail a formal co-investment program. The firm's direct credit origination model naturally creates club-style participations with local banks and family offices on larger financings, but these appear to be structured on a deal-by-deal basis rather than through a standing co-investor vehicle or platform.
Where does the underlying wealth come from for Ameritrust's client families?
The specific wealth origins of Ameritrust's client families have not been publicly disclosed. Given the firm's Tulsa base and history dating to the early 1980s, the client base is likely tied to regional energy, banking, and real estate fortunes that accumulated during Oklahoma's oil-boom and subsequent diversification decades.
Does Ameritrust maintain philanthropic structures, and how is that separated from investment management?
No separate philanthropic foundation or donor-advised fund platform has been publicly associated with Ameritrust. Philanthropic advisory appears to be handled within the broader family-office service model, without a branded charitable entity, distinguishing it from larger MFOs that have spun out dedicated foundations.
