The board shall not on any of the grounds in this section stated, refuse to issue or renew any license or certificate nor shall it revoke or suspend any such license or certificate already issued, except after a hearing, of which the applicant or licensee or the holder of the certificate affected shall be given at least 20 days' notice in writing, specifying the reason or reasons for denying the applicant a license or certificate of registration or, in case of a suspension or revocation, the offense or offenses of which the licensee or the holder of the certificate of registration is charged. Such notice may be served by mailing a copy thereof by registered or certified mail to the last known residence or business address of such applicant, licensee, or holder of a certificate. The hearing on such charges shall be at such time and place as the board may prescribe; provided, that such hearing must be held in the county in which such applicant, licensee, or holder of a certificate has his or her place of business.

Such aggrieved person shall have a right to demand trial by jury by demanding same at the time of the filing with the board of the notice of appeal. The action of the board shall be stayed pending such appeal.
