Garthchester Realty is Westchester, Queens and Riverdale's premiere management company. Established in 1981, Garthchester specializes in property management and sales of co-ops and condominium apartments. What separates Garthchester from the competition is the long-term relationships we have with our clients -- some for more than three decades. We are able to maintain the same level of excellence thanks to loyal staff members, many who have been with Garthchester since its inception.

Clients have always come first and that’s how Garthchester has kept its stellar reputation for all these years. With some 60 buildings under our management umbrella, we are proud to say that many of these buildings have been loyal clients for more than 10 and some even 20 and 30 years. This is what makes Garthchester shine. Our staff works hard to earn the respect of our unit owners and shareholders. For more than 30 years we have brought our buildings exceptional management and high-level service. Read what some of our clients have to say about our work and dedication.
