Denver-based RIA Mercer Advisors on Tuesday announced the acquisition of Charter Oak Capital Management, a wealth management firm headquartered in Portsmouth, New Hampshire, with over $1.5 billion in assets under management (AUM).
The addition of Charter Oak, which also has an office in Kennebunk, Maine, expands Mercer’s presence along the New Hampshire seacoast and strengthens its overall New England footprint, serving clients in Massachusetts also, Mercer said.
The transaction closed on Tuesday, a company spokesperson told WSR.
Charter Oak was founded in 2002 and is led by a partner group that includes Jeffrey Troiano, its Managing Partner and a Senior Financial Advisor; and Partners/Senior Financial Advisors Sarah Serling, also the firm’s CEO, Emma Bean, Todd Cesca, Lena Wyand and Karen Zaramba.
“Charter Oak will transition to the Mercer Advisors brand, the spokesperson said. “This allows clients to benefit from the full weight of a national, top-ranked RIA while continuing to be served by the same advisors they know and trust.”
The Charter Oak team, offices and its relationships with clients “remain intact,” according to the spokesperson, noting the RIA has 19 team members.
“The partner group and key advisors are joining Mercer Advisors as senior wealth advisors, and while some back-office roles may evolve as part of the transition, the priority remains ensuring a seamless experience for clients.”
“Charter Oak exemplifies the type of high-quality, fiduciary firm that strengthens our ability to serve clients and be deeply connected to their communities in meaningful ways,” according to Dave Welling, CEO of Mercer Advisors.
“Their established presence along the New Hampshire seacoast expands our reach in an important New England market and adds a talented, next-generation team committed to comprehensive planning,” Welling said in a news release.
He added, “This partnership enhances our regional depth while reinforcing our long-term strategy of aligning with culturally strong, growth-oriented firms that share our client-first philosophy.”
Charter Oak clients will have access to Mercer’s family office services, including tax preparation, estate and trust solutions and multigenerational wealth strategies, Mercer said.
“The combination also supports next-generation leadership and long-term growth,” Mercer added.
“We always believed there was more we could do for our clients, but we knew we could reach that vision faster with the right partner,” according to Troiano.
“In Mercer Advisors, we found people who value relationships the same way we do,” he said in the news release. “This partnership allows us to maintain the high-touch care our clients expect while expanding the depth and breadth of services available to them.”
According to Bean, “This partnership adds depth and capability to help us enrich their financial lives even more.”
Charter Oak represents the third acquisition that Mercer announced so far in 2026, following Long Run Wealth Advisors, headquartered in Lake Placid, New York, and Poterack Capital Advisory, both announced in January.
Hue Partners was the exclusive financial advisor to Charter Oak for this deal, Mercer said.
