You appear to be well situated financially with a nicely diversified portfolio of investments. Why would you want to change your investment strategy at this point in time when you appear to be doing so well? At your ages you certainly do not need tax-free investment shelters; especially tax-exempt income funds that traditionally pay the lowest rates of return.
So here's what I recommend you do . . . demand a personal financial statement from this alleged investment counselor. If his net worth is at least double yours, give him some consideration. If he is (as most of them are), "saving up his money to invest," get as far away from him as possible. Why should you pay a "counselor" to do things you can do all by yourself?
You can easily find highly rated tax-exempt funds and other mutuals with a good history without having to pay someone a commission to do it for you. You might be bettor off at this time consulting a good attorney to set up a living trust for your children. That seems a better way to protect all of the assets you've worked so hard for than paying a rookie counselor to bleed you dry with commissions.
