We continue to reinvest in our people and platform so that our growth creates more opportunities for teammates and more value for clients.

Regis is Mercer Advisors' multi-family office offering designed for ultra-high net worth families with complex, multi-generational wealth. Regis clients often have the means to build their own family office, and they require a deeply integrated wealth management experience with the highest level of service, coordination, and sophistication. We are a team of world-class fiduciary professionals delivering integrated advice across investments, financial planning, estate strategy, tax strategy, and more with the aim of making every client feel like our only client.

• Serve as the firm's senior-most technical authority on estate planning, personally engaging on the most complex and high-stakes client situations.
• Design and implement comprehensive, advanced estate plans for Regis families, incorporating sophisticated wealth transfer strategies tailored to multi-generational, high-complexity balance sheets.
• Partner with senior wealth advisors, tax strategists, and Regis leadership to ensure estate planning strategies are fully integrated within each client's broader financial plan.
• Own and deepen relationships with a select portfolio of Regis families, with balance sheets that often exceed $100M+.
• Collaborate with clients' outside advisors, including independent attorneys, CPAs, trustees, and family office consultants, to ensure cohesive, comprehensive planning outcomes.
• Lead and represent Regis in prospective client development, industry conferences, and thought leadership initiatives to enhance the firm's profile in the UHNW estate planning market.
• Partner with Regis leadership on practice development, talent strategy, and operational improvements that strengthen the estate planning team's capabilities and client outcomes.

• Demonstrated track record of building and leading high-performing estate planning teams in a wealth management, family office, or private wealth legal environment.
• Deep technical mastery of federal transfer tax law, trust and estate administration, and advanced wealth transfer planning techniques.
• Proven ability to design and implement sophisticated multi-generational estate plans that address the full complexity of a UHNW family's balance sheet — across entities, jurisdictions, and family dynamics.
• Experience advising on business succession, liquidity events (IPOs, M&A exits, ESOP transactions), and the estate planning implications of closely held business interests.
• Prior leadership experience at an AmLaw 100/200 firm, nationally recognized estate planning boutique, multi-family office, or equivalent private wealth platform.
