SAN FRANCISCO — Allison+Partners has bolstered the leadership of its US corporate practice with promotions following a spate of new business wins — Airbnb, Clark Construction and Collier’s International among them.

Jill Feldman (pictured) has been elevated from executive VP to MD of the corporate communications group. Hadas Streit has been upped from senior VP to executive VP and head of the agency’s workplace specialty group. David Baum, also a former senior VP, has been named executive VP of corporate communications and technology.

Feldman, Streit and Baum are all assuming new leadership responsibilities with the promotions that include business development and overseeing day-to-day operations of the practice. All three report to North America corporate president Tom Smith.

Allison + Partners’ corporate practice had a particularly fruitful 2019. In addition to Airbnb, Clark and Collier, the agency added high-profile clients Visa and Qualcomm last fall.
