No.  According to the licensing dept. at the NRED, a corporate broker can only be active for ONE corporation or LLC at a time.  However, that being said, there are circumstances  when a broker licensee may hold dual licenses (this information can found on page 2 of Form 508). For example, if a broker wants to have have both an MLS and a non-MLS office, the broker could be the corporate broker of the MLS office and licensed an individual / sole proprietor of the non-MLS office.
