Spent eight years with SSA as a claims rep and then two years as a radio show Social Security expert on the air in LA). Left SSA and began writing, and will never stop! I speak on Social Security and SSI.
Work and retirement! Focus on early retirement, as well as SSI and disability (and how they interact with retirement). If you're working for yourself or for your own company (and whether you have adult disabled children or not): get some food for thought, moving forward!
