Manhattan, NY On May 24th, several hundred people gathered at the Bryant Park Grill and South Garden to celebrate Syska Hennessy’s 90th anniversary, held in conjunction with the firm’s annual client appreciation party. Attendees represented a wide range of organizations within the A/E/C and real estate communities, along with Syska employees. Gratitude was the theme of the evening–gratitude for clients who keep coming back to Syska and for the talented employees who will steer the firm’s growth in the next 90 years, and last but not least, for the sun, which finally showed up after a week of rain.
