Mercer Advisors has announced the acquisition of Charter Oak Capital Management, a Portsmouth, New Hampshire–based firm with more than $1.5 billion in assets under management. The deal strengthens Mercer’s presence across New England, including New Hampshire, Massachusetts, and Maine.
Founded in 2002, Charter Oak provides integrated wealth management services spanning investment management, tax planning, and estate planning. The firm is led by partners Emma Bean, Todd Cesca, Sarah Serling, Jeffrey Troiano, Lena Wyand, and Karen Zaramba, and is known for its relationship-driven advisory model.
The acquisition enables Charter Oak clients to access Mercer’s broader family office capabilities, including advanced estate and trust services, tax preparation, and multigenerational wealth planning. At the same time, Charter Oak is expected to maintain its boutique identity and client service approach.
For Mercer, the transaction adds a well-established advisory team in a strategic geographic market and aligns with its broader growth strategy of partnering with culturally aligned, planning-focused firms. The firm, founded in 1985 and headquartered in Denver, manages approximately $98 billion in client assets and operates more than 110 locations nationwide.
The deal also supports succession planning and long-term leadership continuity at Charter Oak, while providing expanded equity and growth opportunities within Mercer’s platform. Hue Partners served as the exclusive financial advisor to Charter Oak on the transaction.
