The National IAM Benefit Trust Fund Cares about the IAM Participants

The National IAM Benefit Trust Fund takes care of its participants with medical and prescription drug, dental and vision plans and many more benefits that allow us, and you to continue to be amazing. The main goal is to keep employees healthy by offering affordable, competitively priced health care plans that provide comprehensive coverage. One of the key features of the National IAM Benefit Trust Fund medical plans is that participants have the freedom to choose any provider they want, without needing a primary care physician or referrals for specialty care. Interest and needs evolve over your lifetime.  Likewise, we evaluate our benefits to adapt them to the needs of our changing population.  Take a moment to learn about the benefits available to you and your family.
