Dr. Michael Derwin Dung, MD

For the last 10 years, always 2-4 hours behind the scheduled appointment. Requires appointments 2 or more months in advance, cannot make appointments nights or weekends, by phone or online. Takes forever by writing all notes by hand, does not type, use shorthand, or dictate. Does not allow blood test results to be sent direct to the patient (which is now required due to online results). Does not schedule visits as the patient requests, insists on near the patient's birthday and X number of months after that. Rarely can figure out what is causing your symptoms, tires to think of various blood tests to try, and then is only familiar with the most common drugs to treat, not other treatment options. Often I had to self-refer to specialists because he refused to provide a referral. Unless your health is good or your problems are routine, there are better doctors out there. His staff (wife) can be incredibly rude. He is not generally rude, but he is used to only routine visits. Any… atypical problems generally go unsolved.

Even though you have an appointment, they ask you to call before you come because he is always behind schedule. They say this is for your convenience but it is difficult to plan for. There were times where my scheduled appointment was pushed back 4 hours. On top of that, you still have to wait another hour before he sees you. He does spend a lot of time with you once your in there but like the other person mentioned, he will only discuss what the original appointment was scheduled for. My other issue is that he didn't diagnose my condition properly and didn't refer me out appropriately in a timely fashion letting me suffer for over a month. He is ok for normal wellness visits but was severely lacking when it is something out of his expertise refusing to refer you to other experts...At least in my experience.

Dr. Dung is extremely thorough and spends a great deal of time with me during my annual physical examinations. I would recommend him highly to anyone who is lucky enough to be accepted as a patient and doesn't mind being kept waiting for an inordinate amount of time to be seen.

It's true that you wait a while for Dr. Dung, but he does spend a LOT of time with you. I have been to see him twice. The first time, I waited 45 minutes, but he spent over an hour with me. The second time, my appointment was 1.5 hours after scheduled, but I call first, so it was a fifteen minute wait, and again, he was with me for over an hour. It's true, from start to finish it averages 3-4 hours, but you can minimize the office wait by calling. I only book on my day off, because I'm never sure. I went for a physical, and he spent a lot of time questioning me about my life habits. After blood work, he spends a LOT of time telling you what you could possibly change, and what would be ideal for you. He's the only doctor I've seen that seems to really care. Worth the wait -- definitely.

I don't like the fact that he never seems to be able to keep an appointment time and when I finally get time to see him, if I have a question about another issue, he insist on making another appointment. For example if I have an appointment for blood test and have a question about my pain in my knee. He insist that I make another appointment. This is sooo irritating !!!! Why do I have to wait for another appointment to answer health questions! Aren't you my doctor?!?!?

waiting time is too long , more than one or two hours every visit, can not find the right diagnosis for many years.
