Dental and vision brokers are all over the internet. The only problem is that they are generally offered in specific states. At
www.avesis.com they only work with the states of GA, IA, MD, MA, MN, TX and IN. At
www.safeguard.net their primary markets are CA, FL, NV and TX. Depending upon what state you live in, different programs and insurance options exist. You can also go to your state's department of insurance's website to look for health agents. For example, this is the website for the department of insurance for Texas
http://www.tdi.state.tx.us/. You can google your state's insurance department and look for providers and plans that way.
