I don't know of anyone that hasn't got a good list of providers....but I'm talking about mainly people here in Florida, and winter-visitors from  New York state,  Illinois.. California... Must be you live in a very rural area in the country.   

The USA has made it very difficult to become  a doctor  and why so many are imports and I read there will be a shortage of primary-physicians no matter if you are on medicare or not. .   
For example, my own grandson intends  to go to med school and going into his 4th year is already $20k in debt and that's with a job too. and family help.      What a shameful thing for the USA  when college is free in countries in Europe....and in Cuba 90 miles off our shores Cuba is accepting some americans for training as doctors---free.  

The USA has the greatest economy in the world but we cannot afford to educate our children....rank 37th in healthcare but geezz  how wonderful we have the biggest baddest milliary of a dozen countries combined. and  can go to war at any moment the military--industrial complex needs to make more  weapons and  thus more  money.
