Creative Circle, a staffing agency specialized in advertising and marketing jobs, is opening an office in San Diego, the company announced Tuesday.

Earlier this year, the Calabasas-based staffing firm On Assignment agreed to buy Creative Circle for $570 million in cash and stock, plus an additional $30 million based on future performance. On Assignment had revenues of $1.9 billion last year, and its stock prices soared after its acquisition of Creative Circle.

Creative Circle already has operations in Los Angeles and San Francisco and sees growth opportunities in San Diego.

“With the creative and advertising market continuing to flourish, along with the demand for top tier talent with such great companies in the San Diego area, now is an ideal time for us to enter the market,” said Creative Circle’s Regional Director Greg Detter in a statement.

On Assignment shares closed up 71 cents or 2 percent to $36.40 on the New York Stock Exchange.
