At St. Joseph Cardiothoracic Surgeons, we are experienced in diagnosing and treating a full range of heart conditions. We are one of the largest cardiothoracic surgery providers in the state and have a particular expertise in minimally invasive techniques. Dr. Thomas Molloy, medical director for cardiac surgery, was the first surgeon in Western Washington to perform robotic heart surgery. Dr. Molloy uses the robot for mitral valve repair and other heart procedures.
