OakStreet Wealth Management

OakStreet Wealth Management

Founded in 2017 by CEO Lindsey A. Black, OakStreet Wealth Management operates from Magnolia, Texas, with additional office locations in Houston and Chicago. The firm grew out of a three-decade advisory practice focused on personalized retirement-plan design, structuring itself as a registered investment advisor that serves as a discretionary fiduciary for employer-sponsored plans. Its core client base is business owners seeking custom-tailored 401(k) and profit-sharing structures, a niche shaped by Black's stated philosophy that retirement outcomes matter more than product sales. OakStreet's strategy centers on active, fiduciary-led management across the plan lifecycle: plan design, investment selection and monitoring, recordkeeping coordination, and ongoing administration and compliance. The firm takes 3(38) investment-manager authority, assuming legal responsibility for the selection and oversight of plan investments rather than just offering recommendations. Its target exposure spans mutual funds, collective investment trusts, and managed account platforms, though no specific portfolio companies or named fund holdings are publicly disclosed. Geographically, the firm serves Texas and Illinois businesses, with service reach extending to plan participants nationwide. The firm lists a phone-based client contact model and maintains a lean operational footprint with offices in Houston and Chicago. No team headcount, total assets under advisement, or aggregate plan-asset figures are publicly disclosed. OakStreet's service mix includes plan benchmarking, fiduciary compliance support, and participant education. No private-market vehicles, co-investment clubs, or affiliated philanthropic entities are noted in its public materials. OakStreet's structural differentiator is its narrow focus on small-to-midsize retirement plans where it assumes full 3(38) fiduciary discretion — a posture that shifts legal liability from the plan sponsor to the advisor. This contrasts with the more common 3(21) non-discretionary model, where the employer retains final investment decision responsibility. The firm's concentration on the retirement-plan vertical, rather than broad wealth management, positions it as a specialized ERISA fiduciary for business owners who want to outsource plan governance.
