Pathstone and Mill Creek Capital Combine to Expand Wealth Management Reach

Share

Pathstone is a prominent family office partner-owner managing wealth for ultra-high-net-worth individuals, families, and a few institutions worldwide. This company has signed the agreement to acquire Mill Creek Capital Advisors, LLC. The strategic alliance will greatly increase Pathstone’s footprint in Philadelphia metropolitan area and the Mid-Atlantic region at large. The combined company will handle about $135 billion assets under advisement and administration.

The purchase is a combination of two best, independent wealth management firms on a fiduciary model. Mill Creek is recognized for its well-designed investment program with an institutional flavor and for being deeply ingrained in the Philadelphia business community. It will be a great addition to Pathstone’s national footprint for scale, operational expertise, and the level of client base.

The transaction is subject to customary closing conditions. Legal advisory services for Pathstone were provided by Alston & Bird LLP, while Mill Creek was advised by Cozen O’Connor P.C.

Strengthening Fiduciary Wealth Management Across the Mid-Atlantic

There continues to be consolidation in the wealth management industry as companies want to obtain the scale that would allow them to offer a full range of services to ultra-high net worth individuals. The merger of Pathstone and Mill Creek is a manifestation of common beliefs in independent advice, thorough generational planning, and highly personalized portfolio creation.

By integrating Mill Creek’s team into its existing platform, Pathstone enhances its localized service delivery in the Northeast while introducing its advanced technology stack, specialized family office infrastructure, and expanded alternative investment access to Mill Creek’s clients.

“Mill Creek has built an incredible reputation for investment excellence and high-touch service, which perfectly aligns with our culture at Pathstone,” said Matt Fleissig, CEO of Pathstone. “This combination enhances our capabilities in the Mid-Atlantic region and allows us to bring our robust family office resources to Mill Creek’s clients, while maintaining the personalized focus they have come to rely on.”

Leadership Continuity and Strategic Integration

On top of Mill Creek’s existing leadership team continuing to play their roles actively in the new consolidated organization, this move is also aimed at making the service smooth and the operation stable. This partnership is a way to keep the advisory relationships that Mill Creek has, made locally and over a very long time, while at the same time setting the firm for growth over a very long time under one single corporate name.

“We are proud of what we have achieved at Mill Creek and see this next step as a natural evolution for our clients and our team,” said Joshua Gross, CEO of Mill Creek Capital Advisors. “Joining Pathstone allows us to accelerate our investments in technology, broaden our service offering, and secure an enduring future for our firm while continuing to put our clients’ interests first.”

Operational integration will methodically align the technology, research, and client service models of the two organizations over the next months on a step-by-step basis.

Growth of the Multi-Family Office Model

Incorporating Mill Creek to the team is an important step for Pathstone with ways of execution. One of the very few aspects that comes very high in the list of priorities of Pathstone’s strategic growth roadmap is to look for other very good, very compatible firms in key geographic markets with which to partner.

“Pathstone’s growth is driven by a commitment to partnering with firms that share our values and dedication to client service,” said Kelly Maregni, President of Pathstone. “The Mill Creek team brings deep expertise, an exceptional track record, and strong community ties that will enrich our entire organization as we work together to build the premier family office in the country.”

By building national scale while maintaining a partner-owned structure, Pathstone offers a distinct alternative to institutional wealth management platforms, ensuring that advisory teams remain directly aligned with the multi-generational goals of the families they serve.
