Dr. William Loui came in about ten minutes upon arrival. The nurse checked me in and took my weight and blood pressure. Asked if there was any concerns to discuss with Dr. William Loui. There was none. Waited about three minutes and Dr. Loui came into the exam room. Very timely manner. Everything was finished in about 15 minutes.
