DOs standards do not exceed MD. A DO takes osteopathic manipulation. They are generally best suited for primary care according to their philosophy. It is a little disingenuous when one turns specialist. However I work with many fine DOs and have no problem with them. But they do not have higher standards than MDs
The old joke is what you call someone who didn’t get into medical school? DO!
But I am satisfied they sir for the same exams same boards same everything. So I consider them my equal. But not my superior.
Some schools are better than others and some doctors are too.
