Steven Tenney, Joseph Powers, Helen Andreoli and Jack Piper have partnered with New York consultant Dynasty Financial Partners to launch Great Diamond Partners, a Portland, Maine, independent wealth management firm.

Tenney, Powers, Andreoli and Piper previously managed $530 million in client assets at UBS Financial Services.

Tenney worked at UBS since 1993, most recently as senior vice president and senior portfolio manager. His new title at Great Diamond is CEO and founding partner.

Powers, a former private wealth advisor with UBS since 2000, will lead the financial planning and insurance strategies focus at Great Diamond.

Andreoli, a financial advisor, has two decades of experience in the financial services industry and has worked for Morgan Stanley, Merrill Lynch and UBS. Her new title at Great Diamond is CFO and founding partner.

Piper, a financial advisor with UBS Wealth Management for four years, will have the new title of founding partner. Piper will develop and manage client portfolios with the Great Diamond investment team, and will also work with individuals and families.

The four advisors will work with clients of their new company in preparing and executing business transitions, ranging from intergenerational wealth transfers to the sale of a business, the company said.

Great Diamond will be using Dynasty’s integrated Core Services platform for independent advisors, as well as its turn-key asset management platform (TAMP). In addition, Great Diamond will have access to Dynasty’s technology, including its proprietary advisor desktop; in-house specialists; home office support; and its industry scale.

Tenney said in an email that he plans to initially expand Great Diamond’s footprint in the Portland area, by finding like-minded advisors seeking to join an independent advisory firm, then expanding more broadly into the rest of New England.

“We will consider opportunities as they as they arise in other parts of the country as well,” he said.

Charles Schwab of San Francisco will provide custody services for Great Diamond Partners client assets, while Black Diamond Performance Reporting LLC of Jacksonville, Fla., will provide consolidated asset and performance reporting.
