Rendition of professional services, limitations.

No corporation or limited liability company organized under this act may render professional services except through its members, officers, employees, and agents who are duly licensed or otherwise legally authorized to render such professional services; provided, however, this provision shall not be interpreted to include in the term “employee,” as used herein, clerks, secretaries, bookkeepers, technicians, and other assistants who are not usually and ordinarily considered by custom and practice to be rendering professional services to the public for which a license or other legal authorization is required; and provided further, that nothing contained in this act shall be interpreted to require that the right of an individual to be a shareholder of a corporation or a member of a limited liability company organized under this act, or to organize such a corporation or limited liability company, is dependent upon the present or future existence of an employment relationship between him or her and such corporation or limited liability company, or his or her present or future active participation in any capacity in the production of the income of such corporation or limited liability company or in the performance of the services rendered by such corporation or limited liability company.
