Yes, almost all of them.
If you mean are there any physicians who are board-certified and licensed to practice as attending physicians with less than about twelve years of education, no.
The shortest possible path to holding a license as a physician is: First, complete a bachelors degree that meets the prerequisite requirements for medical school. This is heavy in biochemistry and hard sciences. Very, very, very few people complete a bachelors degree in less than four years. Following graduation, you start medical school which is another four years. After medical school, you must complete a residency in your field (e.g., internal medicine, surgery, med-peds). Residencies are virtually all four years; a few are three and some are five, but most are four. You sit for the second part of the USMLE during residency. You can't hold a license without having passed both parts of the USMLE.
That's four years of undergrad, four years of medical school, and four years of residency for a total of twelve. That's the shortest possible route to being a practicing physician.
