Serving the residents of Long Island, NY for more than four decades

Founded in 1975, CENTURY 21 AA Realty is known throughout the Long Island area for their commitment to treating homebuyers and sellers with honesty and integrity. With offices in Nassau and Suffolk, they deliver superior real estate services to Long Island and Queens. Their world-class agents, outstanding sales and administrative team, and extensive corporate support, have fueled their growth and solidified their reputation as the area’s premier real estate company.

Strong leadership and a keen focus on teamwork and communication have merited CENTURY 21 AA Realty national recognition for excellence. CENTURY 21 AA Realty has consistently scored an overall 99% approval rating for customer satisfaction, performance and recommendations. Their high rating is supported by the tremendous amount of repeat business and referrals from satisfied buyers and sellers. CENTURY 21 AA Realty has been awarded the coveted Art Bartlett 2100 Cup, presented to only one of more than 3,000 CENTURY 21® franchises each year for attaining the highest level of leadership, customer service, and professionalism. Centruy 21 AA is also one of only 34 offices nationwide to be inducted into the CENTURY 21® International Hall of Fame.

They are a diverse group of individuals unified by a consistent concern for customers, a sense of professionalism, and a desire to be involved in work that is meaningful and satisfying. We seek like-minded professionals to join our team.

Barry Levane | Lindenhurst Office

As an agent with CENTURY 21 AA Realty, I’ve been provided with many extraordinary tools and unique advantages that most other agencies do not or cannot offer. One of these outstanding features is our relocation department. Being able to help people relocate nationally and globally is a valuable service. The very capable relocation staff takes care of all of the paperwork and follow-ups allowing me to concentrate on servicing the Client. This department also handles incoming referrals, an invaluable source of leads.

Tom Miller | Seaford Office

“Without the help and assistance from our support staff, I would not have the time or ability to service my clients and customers as effectively as I have, and it would most assuredly affect the growth of my business and my income. We are fortunate to have these dedicated professionals working with us.”

Laurie Hoschke | Lindenhurst Office

Their experience, attitude and training has greatly increased my ability to build a successful career in real estate. The environment and professionalism has allowed me to have a fantastic work lifestyle and assisted me in realizing my career goals and ambitions."
