During our maiden voyage as a co-op, we endured three disastrous managing companies. Very fortunately we were introduced to Garthchester Realty and for the next 27 years it has been wonderful. -Diana Virrill, Board President, Hastings House
In addition to the day-to-day management of building affairs, Garthchester’s expertise has helped to transform The Homestead into a signature building. Under their leadership and guidance we have updated our entryway, vestibule, lobby, hallways, mailroom and canopy, while also upgrading our lighting to LED, resulting in substantial energy savings. With their help we have successfully created an inviting, bold new look for The Homestead. We are proud and pleased to be working with the Garthchester team. -Clementine Carbo, Board President, The Homestead
They are always attentive to our needs and have been instrumental in helping us to bring our co-op’s standard of living to a high level. -Ellen M. Scambia, Board President, 470 Owners Corporation
Garthchester Realty is a strategic and resourceful company. Jay Mendel and his team have managed our cooperative of 103 units since 1985. Garthchester oversaw the refinancing our mortgage of $3.4 million, and that gave us the opportunity to complete three major capital improvements to our building. As a result I have relied on their expert financial advice. Garthchester’s professionalism, knowledge and support are second to none! -Susan Scher, Board President, Chester Hill
I have lived at the Quincy since 1991 and I have seen a complete renovation of this building. From the lobby to the common areas, there have been many upgrades... This is now a great place to live. -Evelyn Copeland, Board President, Quincy
I have been working with Garthchester Management for over 9 years... Their quick response time and valuable professional advice is always welcome and appreciated. The office staff is always very eager to help, our managing agent is on top of any issue that might arise and has a wonderful relationship with our super and board members. The partners are always available for meetings, be it in person or on the phone and are a great resource for information regarding our union or budgetary needs.Garthchester has our trust and they continue to make my job a lot easier! -Stu Levinson, Board President, Cameo House
A few years ago, my Co-op decided to change our management company. We elected to go with Garthchester Realty. It was the best decision that we ever made.

Garthchester provided us with a very dedicated, very competent Managing Agent, who is on top of any issue that the Co-op faces. She is extremely knowledgeable on the NYC ordinances that can impact our building and ensures that we are compliant with all of them. She quickly addresses any issues faced by our residents or staff.

Garthchester has experience with many contractors and vendors, which permits us to get multiple quotes from many qualified vendors for any of our projects. They also provides us with outstanding back office support in handling our finances, our payrolls, staffing issues and sales applications.

I sincerely recommend that if you are reconsidering you Management Company, you should definitely interview Garthchester Realty Company.
-Allen Krieger, Board President, 6636 Yellowstone Blvd. Co-op Association
Placing the management of our Condominium in the hands of Claudine Gruen and her excellent team at Garthchester Realty has proven to be one of the best decisions that we, as a Board, have ever made.

Garthchester has done an extraordinary job of keeping us worry-free in the running of our building by deftly tackling a wide-range of extremely complex issues with skill and efficiency and unmatched expertise to enhancing our staff to the envy of our neighboring buildings in Long Island City ... all while going well beyond what one could expect from a Managing Agent.

For a Board to have little to discuss at meetings, given everything is in order, is truly a remarkable feat ... and how a building should operate ...speaks volumes of the service you will receive with Claudine and her ace team at Garthchester at the helm. For this we are most fortunate and grateful and, enthusiastically, we cannot recommend Claudine and Garthchester Realty more highly for all of their exemplary work!
-Diny Ajamian, Board President, 44-15 Purves Street Condominium
We hired Claudine Gruen and her team at Garthchester Realty to take over management of our building in Long Island City (a new development with 48 condominium units, 17 parking spaces and a commercial component). The previous management company was more of a bookkeeper, even though they were paid to manage the building. Garthchester is the complete opposite. They do a great job with the basic functions of management (staffing, finances, insurance, compliance, application processing, etc.), and she also manages the building as if she owned it. For example, Claudine identified multiple new sources of income, including licensing the top of our elevator machine room to a major television network, she educated the board that the certificate of occupancy permitted personal storage, in a room in the cellar, that we could fit out with lockers, and that could be rented to building residents, as opposed to the previous use of the storage room (a hangout area for building staff). Claudine and Garthchester Realty also meticulously manages the expense side of the ledger and they will not allow the building to overpay for any outside services. She reduced our operating expenses by more than 10% through replacing vendors and other measures, but while maintaining the highest possible service level. Claudine and the team at Garthchester Realty has successfully, safely and cost effectively guided us through Local Law 11 and one of her first acts was advising the board against a building-wide replacement of an antiquated intercom system. Instead, Claudine sourced a cloud-based smartphone video intercom solution that saved the building thousands of dollars and created a superior intercom experience for residents, guests and staff members.

We highly recommend Claudine and Garthchester Realty.
-Patrick W. Smith, Board Member, 10-50 Jackson Avenue
