Contrary to the plaintiff’s argument, the defendants did not waive their right to file a motion to dismiss under Morgan because they filed the motion to dismiss within thirty days of their appearance. See Wightman v. Sposato, 132 Conn.App. 102, 109-10, 30 A.3d 18 (2011). Therefore, the plaintiff’s failure to attach the good faith certificate and an opinion letter of a similar healthcare provider constitutes insufficient service of process and does not subject the defendants to the personal jurisdiction of the court.
