SAN FRANCISCO — Pan Communications has acquired the San Francisco-based tech PR agency Vantage PR, growing the Boston-based firm to $13.5m with more than 100 people across four offices.

In addition to the agency’s Boston headquarters, the acquisition provides Pan with offices in San Francisco, Orlando and New York. Ilene Adler, who founded Vantage PR 25 years ago, will assume the role of chief strategist at Pan. She will be responsible for working with Pan's executive team on integration plans, new strategies and services for the agency, evangelizing Pan's presence in Silicon Valley and enhancing the firm’s international partner strategy.

Rob Adler, Vantage’s SVP, will now serve as EVP and managing director overseeing operations in San Francisco, Orlando and New York and reporting into Pan's founder and president, Phil Nardone.

“We’ve had aggressive plans in place to acquire an agency as part of our long-term growth strategy," said said Nardone.
