Ventura Insurance Brokerage, LLC, headquartered in New York City has specialized in entertainment and aviation insurance for the past 35 years. "Having keen knowledge of the midtown south market, I was pleased to strategically assist Ventura Insurance Brokerage LLC in relocating their headquarters to Midtown South said Howard Poretsky, managing director at Colliers ABR. "After intensely researching various office markets in Manhattan, 475 Park Ave. South will keep the company in close proximity to their client base and will allow for an easier commute for the Ventura staff. After over two decades in one location, my client was quite apprehensive to consider relocating in these times. Any potential move had to be well worthwhile."
