I would like to express my sincere appreciation to Dr. Voon Chi Yen and all the staff at IHH Timberland Medical Centre for the excellent care and support given to my husband. For the past three years, my husband had been experiencing chest discomfort and shortness of breath. We first met Dr. Mdm. Susie at Timberland Medical Centre, who referred us to Dr. Voon Chi Yen for further assessment and treatment. Dr. Voon recommended an angiogram procedure and explained the entire process in great detail, both before and after the procedure. We truly appreciated his professionalism, patience, and the confidence he gave us throughout the treatment. I would also like to thank all the ICU nurses and staff. They were very kind, caring, and attentive, regularly checking on my husband's condition and making sure he was comfortable. Our heartfelt thanks to Dr. Voon and the entire team at IHH Timberland Medical Centre for their dedication and compassionate care. We are truly grateful for everything you have done for my husband. For anyone seeking cardiology treatment, I would highly recommend seeking consultation at Timberland Medical Centre. ❤️
