  • What is your background?
    • I was born and raised in Brooklyn, NY. I have been in this area my whole life. I went to college at Columbia University in New York City. Afterwards, I went to medical school at Stony Brook University in Long Island. I stayed at Stony Brook for my training as well. I completed their residency program in family medicine.
  • What made you want to be a doctor?
    • My parents are immigrants who came from China and Hong Kong. Growing up, I was the interpreter, helping them at doctors visits and other place. This had a huge impact on me growing up and sparked my interest in becoming a doctor.
  • How long have you been a doctor?
    • For one year.
  • What is primary care to you?
    • Primary care is where the patient comes first. It is a patient centric model, which you do not see very much any more. When you integrate this with approach with a doctor that knows the patient very well you get the most out of medical care.
  • What types of medical conditions do you treat?
    • I treat all common urgent care problems like the common cold. I have also practiced primary care medicine as we have patients that come in with hypertension and diabetes. I treat kids and adults. I also do a lot of common office procedures like lacerations, fractures and splinting.
  • What is your approach to care?
    • I believe that in order to provide the best care, you have to have good communicant and a good relationship with the patient. If you can follow this approach, good care will follow. I also believe that patient education is very important. If the patient feels empowered, they will take better care of their own health.
  • What should people look for in a doctor?
    • I think that it is important that a patient feels comfortable. You should look for someone that you trust, someone that you click with well. You should also look for a doctor that does his due diligence and really takes the whole picture into account when caring for you.
  • What is one thing that everyone should do to stay healthy?
    • Exercise. Preventive care is very important!
  • What do you do to stay healthy?
    • Fitness is very important to me. I also love to dance, mainly salsa and some other styles. I began dancing in medical school as a way to relieve stress.
