⭐⭐⭐⭐⭐ 5-Star Google Review for Island Hospital Staff - Exceptional Care and Compassion I recently had the privilege of receiving treatment and staying at Island Hospital from 19/3/24 to 22/3/24, specifically on the old wing 8th floor. I cannot say enough about the outstanding care and support I received from the dedicated staff, especially Nursing sister Thenmoli, staff nurse Thaamilselvi, Natasha Samy, Salina, Hanisa, staff nurse Kayathiri, staff nurse Nanthakumari, Siti Suhana, Navarajini, Nurul Nasuha, and Vannessa. Each member of the team went above and beyond to ensure my comfort and well-being throughout my stay. Nursing sister Thenmoli's compassionate presence and expertise were truly reassuring, while staff nurse Thaamilselvi's unwavering dedication to patient care made a significant difference in my recovery journey. Natasha Samy, Salina, Hanisa, staff nurse Kayathiri, staff nurse Nanthakumari, Siti Suhana, Navarajini, Nurul Nasuha, and Vannessa provided exceptional care with professionalism and kindness, creating a supportive and nurturing environment that made my hospital stay a positive experience. I also want to extend my heartfelt appreciation to Dr. Goh Tiong Meng and Dr. Doreen for their expertise, guidance, and compassionate care throughout my treatment. Their commitment to excellence and patient-centered approach were evident in every interaction, and I am grateful for the high level of medical care they provided. The entire team at Island Hospital, especially those on the 8th floor of the old wing, exemplified a standard of care that exceeded my expectations. Their dedication, compassion, and professionalism are truly commendable, and I cannot thank them enough for their role in my healing journey. I highly recommend Island Hospital to anyone in need of exceptional medical care and personal attention. Thank you to the amazing staff for making my stay a positive and memorable experience. Island Hospital is indeed a place where patients are treated with dignity, respect, and genuine care. Sincerely grateful, Mugkuntrdannaidu Kanagarajau

Greetings, I have called island hospital to book appointment with my follow up doctor which is dorean koey since 2 days when the main line connecting me to the particular clinic no one is answering so how should I book a appointment?
