as refers to the service mark of an organization displayed on signage, etc. Also, what is being used for Chief Professional Officer'

Ah, so you mean a service mark as opposed to a trademark, used to identify a service rather than a product. Also called a servicemark. In that case, Gustavo's suggestion is correct.

FYI, a service mark is unregistered, so you can't use the ® sign.

A ? is usually used to indicate an unregistered trademark. It is an informal notification that there is a public claim as a trademark.

An SM represents an unregistered service mark. It is also an informal notification that there is a public claim as a service mark.

The ® (commonly pronounced R-in-a-circle or Circle-R) is a warning notice to advice the public that the mark is federally registered and their use provides legal benefits. This notice can be used only with registered marks. Use of a ® with any unregistered trademark may result in claims of fraud. Several other countries also use the ® symbol to indicate that a trademark or service mark is registered in their respective systems.
