For those of you that are going through the DOT physical, remember that providers other than physicians are also able to perform the exam. They do, however, need to be certified to perform the exam. Certain APN's, PA's, and Chiropractors can also do the exam. If they're able to do the exam, they'll usually advertise that they can do it. The person administering the DOT physical exam must be listed on the "National Registry of Certified Medical Examiners" or the exam will not be valid. A valid DOT physical exam will only be valid for a certain length of time and you'll be told when yours will expire, keep a copy of the report so you'll be able to refer to it later as to the expiration date. If you're a pilot, your FAA medical doesn't likely substitute for an exam performed under the FMCSA regs, even though the FAA exam likely is a more in-depth and rigorous exam.
