SEI Taps Dimensional Vet to Drive Bank Asset Management Growth

  • Paul Lehman, formerly Head of the Bank Trust Group at Dimensional Fund Advisors, has joined SEI as Head of Bank Asset Management Distribution.
  • Lehman will report to Michael Lane, Head of SEI's Asset Management business, and focus on expanding SEI’s relationships with banks and affiliated wealth organizations.
  • The appointment aims to deepen SEI’s penetration of the bank asset management market, particularly with its OCIO and Co-CIO offerings.
  • SEI manages, advises, or administers approximately $1.8 trillion in assets as of September 30, 2025.

SEI is doubling down on its strategy to serve as a technology and solutions provider for banks seeking to enhance their wealth management offerings. This appointment signals a recognition that banks are increasingly looking to outsource investment management functions to streamline operations and differentiate their platforms. Lehman's experience at Dimensional Fund Advisors suggests a focus on distribution and partnership development within the bank trust space, which has been a key area of growth for SEI.

Distribution Strategy
Lehman’s success will hinge on his ability to integrate SEI’s solutions within banks’ existing workflows and demonstrate a clear ROI, given banks’ desire to consolidate vendor relationships.
Competitive Landscape
The competitive response from other asset management providers targeting the bank wealth management space will be important to monitor, particularly those with established relationships.
Regulatory Headwinds
Increased regulatory scrutiny of outsourced investment solutions and fiduciary responsibilities could impact the adoption rate of SEI’s OCIO and Co-CIO offerings within banks.
