TTMA members are privately owned and operated businesses that are part of an industry generating annual sales in excess of $40 billion.

    TTMA provides members with networking opportunities, group Ohio Workers' Compensation discounts, industry news regarding technical advances and legislation, and supports various workforce development initiatives.
