I don't mind going to any physician that charges reasonable rates. Moreover, as a former patient care tech I know the simple routine. I can take my own blood pressure, height, weight, listen to my breath sounds and complete a physical history assessment form.
It is like me changing my oil at a reasonable cost as opposed to going into a truck center oil change facility that charges a grossly high price for simple service.
You cannot do annual blood work which EVERYONE should have done. I am a former EMT and can do BP etc. I cannot do blood tests. Just a fact. Even IF a DR cost $100 per visit that is NOT much for a YEAR!! We all spend more on junk every year than that. I don't know what reasonable is for you or where you live, I pay $50 per visit and my wife pays $65.
