HighTower has made three strategic executive hires, including veterans from Fidelity and Private Advisor Group, the company says.

Abby Salameh has been named HighTower’s chief marketing officer, tasked with heading the corporate and field marketing teams, according to a press release from the firm. Salameh has been in the financial services industry for more than two decades, most recently serving as CMO of Private Advisor Group, HighTower says.

Additionally, Catherine Davies, another veteran with more than 20 years in the industry, has joined HighTower as its chief of staff and head of business management, according to the press release. She’ll be responsible for overseeing several cross-enterprise initiatives and supporting the executive team, HighTower says. Davies joins from Fidelity, where one of her responsibilities was to oversee the HighTower relationship, according to the press release.

HighTower has also named Greg Fink head of advisor success, who’ll head a team responsible for deepening relationships with advice firms, developing strategy and shaping annual business plans for organic and inorganic growth, the company says. Fink too has been in the industry for more than two decades, most recently serving as president and CEO of ACG Wealth, according to the press release. Before ACG Wealth, Fink was vice president at Fidelity Clearing & Custody Solutions, HighTower says.

HighTower, backed by private equity firm Thomas H. Lee Partners, has been on a growth spurt this year. Earlier in May, the firm announced that it lured two financial advisors previously overseeing $400 million at Fieldpoint Private. In April, HighTower took a stake in a newly merged RIA in California that oversees $4.8 billion. And in February HighTower acquired a $2.6 billion RIA in Memphis, Tenn.
