C. chapter 30, subchapter II, by the Board of Mental Health and Chemical Dependency Professionals; neither that law nor the board's rules (24 Del. Admin. Code 3000) say anything about business structure. A Delaware LLC may carry on any lawful business, purpose or activity except banking (6 Del. C. 18-106(a)), so a licensee may practice through an ordinary LLC; its name must contain "Limited Liability Company", "L.L.C." or "LLC" (6 Del. C. 18-102(1)).

C. 603(1) covers only licensed services that, "by reason of law, prior to June 7, 1969, could not be performed by a corporation," and its example list does not name this profession.
