Mercer Global Advisors, a large registered investment advisory firm based in Denver, is expanding its presence in the New England market with the acquisition of Charter Oak Capital Management, an RIA based in Portsmouth, N.H., with $1.5 billion in assets under management. The deal closed Tuesday.

Mercer says Charter Oak has a strong presence in the southeastern corner of New Hampshire that touches the ocean and serves clients in neighboring Massachusetts and Maine.

"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," says Mercer CEO Dave Welling.

The deal follows Mercer's acquisition last year of O'Brien Wealth Partners, a $1.1 billion firm based in the Boston suburb of Waltham, Mass. The Charter Oak acquisition is the third transaction Mercer has announced this year.

"We are seeing strong interest from high-quality firms across a range of sizes and markets," a Mercer spokeswoman says.

Mercer adds 19 staffers through the acquisition. In addition to its base in Portsmouth, Charter Oak maintains an office in Kennebunkport, Maine. Charter Oak's partners -- Jeff Troiano, Emma Bean, Todd Cesca, Sarah Serling, Lena Wyand, and Karen Zaramba -- join Mercer as senior wealth advisors.

Aside from a handful of charitable organizations, Charter Oak's client base is entirely retail, with the bulk of its assets under management held by high-net-worth individuals. The firm says it offers a holistic wealth management service that includes investment management as well as tax and estate planning, a service model that should expand with the backing of Mercer's resources.

"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," Troiano says. "This partnership allows us to maintain the high-touch care our clients expect while expanding the depth and breadth of services available to them."
