    Very knowledgeable and gave me information about costs for tests needed. He advised which laboratory has better prices and to ask for the cost before having the lab work done. If the cost of the lab work is going to be over a certain amount he advised I should come back to a script for another lab under my plan.

    I probably would not recommend Dr Yu, because one would never know when Optum would fire him.

    Would never recommend. Spent less than 5 minutes. Told me I had a mild heart attack ( further test and appt concluded I did not). Showed no concern. He mumbled and spoke very softly. Had to ask him to repeat several time. NO bedside manner. Does not well represent your practice

    He listened. He wasn’t judgemental. He asked questions and diagnosed my problem. Ordered test, prescribed meds and called me with lab results and instructions the following two mornings.
