KPJ Klang Hospital is indeed the choice for me and my family. All the staff at KPJ Klang are good and very helpful. For admissions to the ward, the rooms provided are comfortable with reasonable prices. Only the food options in the ward need improvement. That is my opinion. Regarding parking, perhaps patients who are admitted or have appointments at the clinic could receive special benefits by getting free parking. For the doctors, specifically for Gynaecology, if you need to remove fibroids without major surgery, you might consider seeing Dr. Vijay. He has new technology for surgery using a 3D laparoscopy system. Dr. Vijay is an experienced Gynaecologist, very good, and will patiently answer all your questions. Clinic staff Ms. Ila is also very experienced and friendly. For the Paediatrician, I really like seeing Dr. Ooi. She is an experienced doctor, very good, and caring. Her clinic staff are also very experienced and friendly. For the ENT specialist, my choice is definitely Dr. Vincent. Come and see him if you have any ENT problems. He is very, very helpful and will patiently answer all your questions. His clinic staff are also very experienced and friendly. Overall, come to KPJ Klang because there are many good specialists here. Thank you.
