## About

Founded in Oklahoma City in 1990, T.S. Phillips Investments originally operated as an independent registered investment adviser serving local individuals, banks, and business entities. The firm was later acquired and merged into Thurston Springer Financial, an Indianapolis-based full-service broker-dealer and registered investment adviser, which now serves as the parent entity. The merger absorbed T.S. Phillips's client book and advisory staff, integrating them under Thurston Springer's broader advisory platform while retaining the Oklahoma City office as a branch location. The firm provides discretionary and non-discretionary asset management to individuals, institutions, and business owners. The website does not disclose specific asset-class weightings, but language on the platform emphasizes retirement planning, wealth building, and asset preservation — typical retail wealth-management services. No direct investments, co-investments, or named portfolio companies are publicly attributed. The firm's operational scope appears limited to traditional brokerage and advisory client relationships rather than institutional deal-making or fund management. No current AUM, team size, or deployment figures are published. The contact page lists a single office at 3401 NW 63rd Street in Oklahoma City. The parent, Thurston Springer Financial, maintains a broader midwestern presence, but T.S. Phillips itself discloses no additional offices or affiliated vehicles. There is no public mention of philanthropic foundations, club memberships, or alternative investment vehicles tied to the brand. Structurally, T.S. Phillips Investments is a local advisory practice rolled into a regional broker-dealer — a consolidation archetype common in the independent wealth-management channel. The merger eliminated standalone branding beyond a legacy website and phone number. Without reported AUM or a distinct investment mandate, it functions as a client-service unit of a larger organization rather than an autonomous asset allocator or family office.
