call the new doctors office, see if they are taking new patients, if they take your insurance, then make an initial appointment also known as a meet and greet. You could also go in person to the office to find out info instead of over the phone, and talk to the staff about what your medical problems are and see what feeling you get from the office staff before you make the first appointment.

I had a good pcp who moved to colorado. I have been through a few pcp's since. IM still not really happy with who i have now but im having trouble finding anyone who is any good where i now live. I have specialists who i travel to and am happy with but a pcp should be close.
