I've had only one or two endos in the past 30+ years who was also a good front-line doctor. At many endo practices today the CDE's are doing all the front-line work, and obviously they vary in usefulness.
If you already know more than your endo (and you may), you might want to switch your schedule around to see a good non-endo doctor maybe 4 times a year, with only yearly visits to the endo.
Not sure exactly how old you are but if you started off with a pediatric endo, I can warn you the transition to non-pediatric endo care can be very tough and you may very well be dissatisfied with the change.
Even finding a good non-endo doc can be hard. I wouldn't "quit" your current endo practice until you find something you truly are more comfortable with.
Some pump-promoting endo practices, you will find, don't offer much personalized care either, and put all their patients on the same pump kinda like an assembly line.
