      5 stars to Dr Kelvin Voon, GI specialist. 1st time there with my son. Arrived around 9:30am. Was told by nurse doctor usually in at 10:30am but was called B4 10am. Did urine, blood test and CT scan. Saw Dr maybe around midday B4 lunch. To admit for observation as having diarrhea over a week and right abdominal pain. Only admitted after 5pm. Don't know whether insurance or hospital admin fault. Anyway, still 5 stars coz even after 5:30pm, Dr Kelvin Voon visited ward and submitted appeal to insurance company coz declined and only officially informed via text at around 5:05pm. Later approved after appeal. Tq Dr Voon.

      I was admitted to Sunway Medical Centre Seberang Jaya, Pulau Pinang, and overall I am very satisfied with the service provided. I would like to express my sincere appreciation to my doctors, Dr. Soon King Choon and Dr. Kevin Voon, for their professionalism, clear explanations, and attentive care throughout my treatment. They took the time to listen, explained my condition patiently, and ensured I was comfortable and well informed. Special thanks to the physiotherapy team, especially Cik Bella , for their encouragement, gentle guidance, and dedication during my recovery sessions. Their positive attitude really helped boost my confidence and healing process. I would also like to thank Cik Hanun and cik Sofia from the Food & Beverage team for her kindness and helpful service. The meals were well managed, and staff were always polite and responsive to requests. Additionally, all the nurses , security, cleaning staff were consistently polite, respectful, and helpful. They created a safe, calm, and supportive environment during my stay. Overall, the service, cleanliness, teamwork, and patient care at Sunway Medical Centre Seberang Jaya are excellent. I truly appreciate the care and compassion shown by everyone. Highly recommended.

His reassurance and explanations really helped me feel less worried throughout the whole process. I would also like to thank all the caring and attentive nurses who took such good care of me throughout my stay.
