New location supports commitment to grow its CFO Strategic Advisory practice and integrated finance, operational, and strategic advisory services business

NEW YORK, Sept. 9, 2026 /PRNewswire/ — Geller today announced the opening of its new headquarters at 99 Park Avenue. The new office space is designed to support the firm’s continued growth and strengthen collaboration as demand rises for its integrated finance, operational, and strategic advisory services.

Founded in 1984 by Martin Geller, the firm has long served both established and emerging growth companies across their most complex operational and financial needs. The relocation underscores Geller’s long-term commitment to New York and marks a major milestone in the firm’s history.

“The move to 99 Park Avenue is an exciting reflection of the growth we see ahead for Geller and the strong demand for the best-in-class integrated services we provide,” said Martin Geller, Founder and Chairman of Geller. “This new headquarters is an investment in our people and culture, and in the capacity we need to continue serving clients at the highest level for years to come.”

The opening comes as Geller continues expanding its capabilities with the formalization of its CFO Strategic Advisory Services practice. As announced earlier this summer, Geller welcomed Corinna Creedon as Managing Director to lead and expand the practice, providing senior financial strategy officer services, finance operations advisory, and digital transformation advisory. The practice will build on Geller’s deep expertise in serving nonprofit institutions, as well as SaaS and emerging technologies, commercial, and private equity-backed organizations.

Located near Grand Central Station in Midtown Manhattan, 99 Park Avenue recently completed an extensive capital development program, delivering upgraded infrastructure, modern workspaces, and new amenities for tenants designed to foster productivity, collaboration, and employee engagement.
