I am very satisfied with all your people. They are diligent, very responsive, very very well trained and a pleasure to work with. - Earl Smith, Owner Maple Gardens
The management team here Forest Hills Housing Cooperative goes the extra mile to ensure that our shareholders are accommodated in many different ways. Their experience with problem solving issues, and their ability to give a hundred percent of support to our Cooperative. - Anonymous
I really like living here because it has that friendly community feel. The maintenance department is so very hard working but will always say hello. It is a family feel here. The office has the most polite people. They really listen and really care. If you have a problem they are there to listen. - Jeannine Gonzales, Resident Newport Heights
We meet monthly with the TMC Property team and executive members of their administrative office on Monthly Financial results and other related matters. The TMC Staff are always very well prepared. Over the period of time that I have been employed by my organization, these meetings have been very helpful to discuss our properties and activity with facilities and capital investment. TMC has a large team that is present on the properties, and this often makes it very easy if an issue arises, to meet with them.
