He's not with me in my clinic, he's working in a private laboratory. His office is located about 10 minutes away by car. Sometimes when discussions are needed, he come to my clinic to see and discuss the patient in person. He is 58 years old. The biggest memory I have received through him is hard work and sincerity in his work. In some cases, if there was anything to reserch, he worked all night and left work at 4 or 5 am in the morning. When he works, he doesn't do anything roughly. He always strives to get things done perfectly. His sincerity makes others trust him. I always respect his sincerity.
