Professional limited liability companies (PLLC's) are corporations
and limited liability companies organized for the purpose of providing professional services. Usually, professions where the state requires a license to provide services, such as a doctor, chiropractor, lawyer, accountant, architect, or engineer, require the formation of a professional corporations or PLLC. With professional entities, the proper state licensing body must often approve the formation documents before these documents can be filed with the secretary of state. Further, the articles typically must contain the signature of a licensed professional as the incorporator, and that person's license number, or a certified copy of the license may be necessary as part of the filing requirements. As a result, the filing time for professional entities may be longer than the filing time for standard business
You do not have to form a PLLC if you are a doctor, however the advantage is that if you are this lets the world know that your are a professional and your license has been approved by the appropriate state board.
