    Been seeing doctors and nurses since surgery last year, they've all been a huge help to help me get through my illness and surgery. Thanks to my doctors Dr.Margaret, Dr.Teoh, Dr.Jeffrey & Dr.Jennifer, without them I wouldn't be able to write this review. Thanks to all the nurses from CCU, A&E and normal ward, they took good care of me during my admission. Special thanks to Yong, Kak Ika, Kak Su, Kak Siti, Ain and other nurses at Tower A 5th floor for their constant kindness and support. The doctors and nurses encouraged me alot and gave many information for me and my husband to deal with after treatment & surgery care. I can't say I'd love to go back to the hospital 😅 But SunMed would definitely be my first choice.

    Perkhidmatan kesihatan swasta yang berkualiti. Barisan petugas kesihatan yang sangat berdedikasi. Tidak ketinggalan juga staff bukan kesihatan seperti Rino yang banyak membantu semasa saya berada di wad. Sangat recommended utk mendapatkan perkhidmatan disiniI came for Orthopaedic Clinic today (22/11/2024) with Dr Lau Choon Ping due to my problem with spine. Dr Lau is my favourite specialist because he always have solution for every problem that I have. He perform laparoscopic spine fusion for me in 2021 and even recommend me to see Dr Jennifer for my cancer treatment. Its been a smooth journey for my treatment here and I recommend everyone to come and get the best treatment here
