We as a family are so thankful to the whole surgical team for all their wonderful support during my mother’s stay and operation in the hospital. We have no words to express our gratitude to the surgeon Dr. Micheal and the Endocrinologist Dr. Yong for their continuous commitment, care and concern shown to our mum. Also like to thank Dr. Zul and his anaesthetic team. The nursing staff in the surgical ward were exceptional in all their care, always ready to help with a smile. The physio team, specially Adlin and Shalini have been very motivational and encouraging in her rehabilitation. All this has resulted in our mother’s good recovery. The catering team, to mention Gayathri, were also exceptional in their care, accommodating to all our needs. Giving thanks to God for everything. Thank you from Jessy, Joseph and Mathew.
