I am in Texas, but my consultancy is global. I advise parents to move where they (the parents) feel most supported and comfortable. Before the actual move, call that state's committee on people with disabilities, out of the governor's office. Become friends with that person and ask them for a referral. Become friends with the referral with regular follow-up and check-in. The key is to engage with whomever you are working with, wherever you end up residing. The other key is to get a name of at least one or two parents in the community. If there is a support group, join it. If there is not a support group, start one. It will be respite time and a joy for you to have a friend in your new area. Best wishes! You are gong to make it! Deb

I'm sure how the states rank by Medicaid. You may want to check out this source.

I've been trying to move out of Georgia and would like go to the Great Lake states mostly but I applied to jobs in Texas. Here's how ranked them on other threads. Also remember that when some people talk about bad experiences in some states you may to see how long ago they posted that info. Things may have changed so take that into account.

Indiana
California
New York

If you're happy with Florida you may be satisfied in a lot of states as FL services aren't highly praised. Dualspectrumdad had some good advice.

I would stay away from the southern states, they tend to be behind the times. The best State is MA and then NJ, NY MN, PA and WS to name a few. The other good thing about the north east is that the medical care is top notch, MA is the best in the country.

The drawback to this is that the cost of living is higher in some places. What you have to consider is places where there are more taxes there are more services because the state is involved in paying for those services. Stay away frm tax free states for this reason. Now you can find cheaper places to live within the top states but you have to do your research to find them. Often that means living in a small town instead of a metro area, but the plus to that is that you will find more people willing to help with local organizations.

Of the list you provided I have heard bad things about Texas, Arizona and Georgia so I would stay away from those, and I suspect Tennessee being in the south as well would not be good.
