Warner Family is a well-oiled machine, which is good, they're very efficient, but it does leave it up to the patient to make sure he or she is seen and treated as an individual.
I've found it easy to get in for unplanned visits (as long as it doesn't matter who you see), but they book physicals (which they pretty much make you do on an annual basis to be seen for anything) way out.
The office was in walking distance of my first place when I moved to Chandler, but since then I've moved to North Scottsdale, but I still make the drive because despite some hassles, I do believe I get good care. Mornings are pretty crowded and you may end up waiting, but I've been in the mid-afternoon and it was mostly empty and pretty quick to get in.
