I have been admitted a few times to CMH under Datuk Dr Nagappan, who is a senior consultant and a highly experienced doctor. He is extremely calm, kind, and approachable. Such a friendly and reassuring doctor. Special thanks to Dr Nagappan for his excellent care and treatment. My family and I feel truly blessed to know you. You always make sure I am well and stable before discharge, which gives us great peace of mind. I would also like to express my heartfelt appreciation to the Jasmine Ward nurses. During my recent admission, all the nurses were incredibly caring and attentive. They constantly checked on me, were very friendly, and made me feel comfortable and safe. The way they care for patients truly makes the environment feel like home. No matter how many times help was needed, they were never frustrated and were always ready to assist with a smile. Not forgetting the housekeeping staff and food delivery team—they were all very polite, friendly, and supportive as well. Overall, CMH is one of the best hospitals. The care, professionalism, and compassion shown by the entire team are truly commendable. Thank you, CMH, for your excellent service and dedication.
