Anyone use any of the retirement planners who specialize in the Feds?

Am a Fed. Mid 40s. 22 years service.

I get emails nearly daily from various retirement planning firms wanting to set up appointments for a review of retirement benefits and retirement planning. These also come in the form of seminars and whatnot.

Are any of these worth responding to? Any firms better than others?

I attended a retirement planning seminar once at our facility and it seemed to be not worth the time. However, it does seem like a majority of employees don’t have an understanding of how the various components of our benefits work - based on the sorts of questions asked.

I recognize that there are lots of little tips and tricks related to FERS, but at some point deciding the ‘best’ day to retire should seem less important than what some of these people advertise.

Suggestions?
