Very knowledgeable and friendly. There is a reason he is so busy. He is good at what he does. I found the receptionist to be extremely helpful and kind. Communication and messages were returned promptly. She greeted all the patients with a smile, which I found to be a great change from my previous experience in other offices. Dr chun made me feel important and taken care of. Would highly recommend. The only reason I give 3 stars for punctuality is because he does run late occasionalit due to emergencies but that is understandable and he makes up for it. HIGHLY RECOMMEND.
He would not return any calls to have the paperwork for testing at the hospital fixed. Went to the office 3 times and no response. I ever slid a note under the door and again nothing. I gave up and never had any blood or urine tested.
