United Capital Financial Partners, a six-year-old wealth advisory firm, added three new offices to its rapidly expanding footprint, acquiring the assets of M&T Bank’s Zirkin-Cutler Investments in Bethesda, Md, as well as MarketSpace Financial in Albuquerque, N.M., and Sovereign Wealth Management in Memphis.

Since it was formed in 2006, United has acquired 30 independent firms.

United’s goal is to acquire its was into a significant presence in the nation’s wealthiest 25 cities. Joseph Duran, co-founder and CEO of the Newport Beach, Calif.-based firm, says it’s two-thirds of the way there with a footprint that already spans 12 states.

United’s firm isn’t all through acquisition—it pulled in $300 million in new assets last year, double the year before. Its 35 advisors now manage a total $13 billion in client assets, both for individuals and institutions.

Duran hopes to double advisor headcount in key cities in the next few years. United is targeting advisors with a minimum of $100 million in assets and $1 million in fee-based production, but its average advisor manages $250 million and produces between $2 million and $3 million. Advisors joining the firm get a stake in the company and typically grow client assets my 19% in the first year thanks to the firm’s focus on planning over products, Duran says.
