"The staff was warm and friendly offering you bottled water and coffee. Each person you met introduced themselves, told you what they do, where they were taking you and what was about to occur. The equipment was sterile and everything was prepared already for you. Dr. Chanbo was so friendly and welcoming and appreciative, thanking you for coming. The service, the office, the staff took me back to the days when customer service was highly regarded and people really took pride in their job..."
