Members gather at NGMA’s Spring Meeting

The National Greenhouse Manufacturers Association is a professional trade organization for the manufacturers and suppliers of greenhouses and greenhouse components.

Mission of the NGMA
  • To serve the interest of the industry and its members.
  • To gather, develop and disseminate information vital to the greenhouse industry.
  • To provide a forum for the development of interrelationships and idea exchange.
  • To explore existing and new markets.
  • To give meaning to the customer, growers and users of greenhouses.

There are four classes of membership in the Association. Membership (other than honorary, university or extension) is extended to the company, rather than any individual. Determination of membership eligibility and classification is the responsibility of the Board of Directors. In addition, the Board may also by a majority vote, dismiss or sanction any NGMA member whose conduct is deemed detrimental to the organization.
