No corporation organized and incorporated under the Nebraska Professional Corporation Act may render professional services except through its officers, employees, and agents who are duly licensed or otherwise legally authorized to render such professional services within this state. This section shall not be interpreted to include in the term employee, as used in the act, 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.
