I brought my father to see him after being recommended by our friend. Waited an hour plus as many patients in his clinic. However, worth waiting as the doctor is very detail and able to give us clear explanation of my dad unresolving problem after seeing so many other doctors including some ent doctor around. After the first visit, my dad condition improved by more than 50% and condition healed after the second visit when he just continue my dad medication from his first visit. Look very young but very detail doctor.
