I've been a physician for over 40 years. I have seen the devolution of medicine from patient-centered, where the doctor was your advocate, to $$$ centered, where the patient is a financial opportunity. And I mean for Insurance companies and hospital organizations, not so much for the doctors.
It is rare to find a physician who is not owned and operated by some iteration of theses 2 organizations. The government is the other big doctor employer. As an employee, the physician has become a "double agent", incentivized to withhold care, rather than provide it.
Look long and hard to find that rare independent physician, and you likely have found a good one.
I was lucky enough to find a physician that is 1 year older than me, and very active. He sees my health as "opportunity", not a restriction.
You can check with the American Association on Physicians and Surgeons in Tucson, AZ. They are an active voice for the few remaining independent physicians. They can provide you with a list of independent doctors in your area. Members of this group of physicians were the ones that championed early outpatient treatment of COVID-19 (Peter McCullough, MD is one such physician). It was their contention that early intervention with repurposed existing antiviral medications would be effective in preventing hospitalization and death. Turns our they were right! They were instrumental in saving hundreds if to thousands of lives.
Finding such a doctor when you are still healthy will be a real plus as you ascend the age ladder and run into its inevitable challenges.
