N-Y ASSOCIATES, INC provides professional services in the areas of consulting engineering, architecture, and planning. N-Y was established in 1969 and has offices in Metairie, Louisiana and Biloxi, Mississippi. While the N-Y organization is large enough to offer a variety of special services, the firm also personally assists its clients from the very early planning stages of a project to the completion of production. This coupled with the firm's ability to meet schedules and adhere to budgets are some of the reasons why N-Y historically has so many repeat clients. A personal service organization is only as good as its staff. N-Y has assembled a group of skilled individuals as diverse in background as the various projects they design. Each person offers different facets of experience and knowledge, creating a forum for the exchange of ideas and the development of innovative solutions for our clients' needs. N-Y is dedicated to providing high quality, timely cost-effective planning and design services - strongly believing in a management system that provides a close personal and business relationship with its clients. We employ a cadre of professionals who recognize that the client's needs, whether large or small, are the foremost considerations in project design. N-Y's broad-based experience in engineering, architecture and planning can be an asset to you on your next project. If you are contemplating a project - large or small - or simply need some information, feel free to contact us.
