The Mather Group Acquires Sebold Capital in Strategic Play for Business Owner Market

CHICAGO, IL – April 30, 2026 – The Mather Group (TMG), a prominent wealth management firm with $17 billion in assets, has announced a strategic partnership that will see it integrate Sebold Capital Management, a boutique advisory firm renowned for its specialized work with business owners. The move signals a deliberate effort by TMG to deepen its expertise in one of the most complex and lucrative segments of the high-net-worth market, reflecting a powerful trend reshaping the financial advisory landscape.

Sebold Capital Management, founded in 1998 by Sean and Kelly Sebold, will become part of The Mather Group, bringing its focused expertise to TMG's national platform. The partnership is designed to enhance TMG’s ability to provide comprehensive, integrated financial solutions for entrepreneurs navigating the intricate connections between their business enterprises and personal wealth. This collaboration underscores a strategic push to offer a more profound level of coordinated advice, ensuring client continuity while expanding available resources.

A Strategic Move in a Consolidating Industry

The TMG-Sebold partnership does not exist in a vacuum. It arrives amidst a period of record-breaking merger and acquisition activity within the Registered Investment Advisor (RIA) industry. Driven by private equity investment, the pursuit of scale, and an aging demographic of firm founders seeking succession plans, the wealth management sector is undergoing significant consolidation. In this competitive environment, acquisitions are increasingly focused not just on adding assets, but on acquiring specialized talent and niche capabilities.

This transaction is a textbook example of a strategic acquisition designed to enhance a firm's value proposition. Rather than simply absorbing a competitor, TMG is integrating a specialist to bolster its service offering in a key growth area. The industry has seen a clear shift from generalist M&A to strategic acquisitions that add specific expertise, such as tax consulting or, in this case, sophisticated financial planning for business owners. These “integrator” deals, where a firm is fully brought into the fold, are becoming more common as acquirers seek to create a seamless and unified client experience.

Jennifer des Groseilliers, CEO of The Mather Group, highlighted the strategic intent behind the move. “Our clients are not facing one decision at a time. They are making interconnected decisions that shape their financial future,” she said. “This partnership strengthens our ability to bring those elements together with greater depth and coordination, while continuing to deliver the integrated experience our clients expect from The Mather Group.” The involvement of FP Transitions, a leading M&A advisory firm specializing in the wealth management space, further indicates that the deal was structured with a focus on successful long-term integration and strategic alignment.

Beyond the Balance Sheet: Serving the Modern Entrepreneur

Business owners represent a uniquely challenging and rewarding client segment. Their financial lives are inherently complex, with personal wealth often deeply intertwined with the value and cash flow of their companies. Decisions about business growth, capital investment, and employee retention have direct impacts on their personal balance sheets, retirement plans, and estate strategies. Traditional wealth management has often struggled to bridge this gap, focusing more on liquid assets than the holistic picture.

This is precisely the niche that Sebold Capital Management was built to fill. The firm carved out a reputation for helping entrepreneurs navigate critical inflection points, including growth financing, succession planning, and major liquidity events like the sale of a business. Their approach centers on coordinating the financial intricacies of the business with the owner’s personal financial goals.

“Business Owners have a different mindset,” said Sean Sebold, founder of the eponymous firm. “They are continually looking to add value to their clients, their community and their families. Our role is to coordinate business finance to personal finance, with all its complexity, to ensure business owners are executing on their own value mandate.”

By integrating this specialized expertise, TMG aims to provide a more robust service that addresses the full lifecycle of an entrepreneur's financial journey. This includes everything from managing concentrated equity positions and implementing tax-efficient exit strategies to planning for the next generation. The partnership promises a high-touch, client-centered experience that can manage the multifaceted financial decisions entrepreneurs face daily.

Building an Integrated, High-Touch Wealth Platform

The integration of Sebold Capital Management is a significant step in TMG’s long-term strategy to build a modern, comprehensive wealth management platform. The firm has consistently emphasized its integrated model, which aligns financial planning, investment management, tax strategy, and estate planning under one coordinated team. The addition of Sebold’s deep expertise in the business owner segment enhances each of these pillars.

For existing Sebold clients, the partnership promises continuity of service from their trusted advisors, now backed by the expanded resources of a larger national firm. For TMG’s existing and future clients, it provides access to a deeper well of specialized knowledge for navigating the complexities of business ownership. This move positions TMG to compete more effectively not only with other large RIAs but also with private banks and multi-family offices that have historically courted the entrepreneur market.

Ultimately, the partnership reinforces the idea that the future of wealth management lies in delivering deeply specialized advice within a fully integrated framework. As client needs become more complex, firms that can offer both broad capabilities and niche expertise are poised to lead the industry. By bringing Sebold Capital Management into its fold, The Mather Group is making a clear statement about its commitment to providing that elevated level of service, ensuring clients can plan with confidence while focusing on what matters most to them.
