Our agents are known in their communities for their integrity and the exceptional level of service they provide.

Local Expertise. Global Connections.

It may be said that Allison Bandier Koffman, a Senior Global Real Estate Advisor and Associate Broker with Sotheby’s International Realty, has real estate in her blood. Allison has chosen to follow the imposing footsteps of her grandfather, the legendary developer, Samuel J. LeFrak and of her mother, Denise LeFrak Calicchio, a top Sotheby’s International Realty broker and co-author of the New York real estate bestseller High Rise, Low Down. Allison has proven herself worthy of her family’s legendary reputation; since joining Sotheby’s International Realty, she has been one of the company’s top producers.

Allison received her B.S. in economics and finance from the Wharton School of Business at the University of Pennsylvania. There, she developed the business skills and knowledge that were to form the foundation for her future success. However, it is Allison’s personal work ethic that makes her shine.

Renowned for her spot-on instincts and attention to detail, Allison will go to any lengths to find the perfect fit for her clients, both uptown and downtown. This single-minded focus, coupled with her superior client skills, has earned her a reputation for professionalism, perseverance, and discretion.

For more than a decade, Allison has partnered with fellow broker Juliette Janssens. Their business acumen, discernment, in-depth familiarity with the city’s neighborhoods, and sophisticated marketing materials set them apart. Their expertise covers all areas of Manhattan, and their understanding of the nuances of New York real estate allows them to help clients navigate that daunting world with ease. In addition to working with buyers and sellers, they have successfully represented new development projects on the Upper East Side, providing them with unique insights that expedite successful deals. Their trusted partners in other markets facilitate transactions outside the Manhattan area. Allison and Juliette are consistently ranked as top producers at Sotheby’s International Realty, with over a billion in sales.

Allison lives on the Upper East Side.
