I did my ADHD/ADD testing in here. It costed between $125-150, TOTALLY WORTH IT!Dr. Yi Du did my testing and she was just wonderful. I have never met someone like her. I am very, very hesitant to share about my problems even to psychologists, medical doctors or anyone. But I was so conformable with Dr.Du. It was so easy to open up with her and she listens and respond. Try to share whatever that bothers you.I did the testing for 3 consecutive weeks. The test was between 1-2 hours. It depends if you want to take breaks in between the tests. She shares her findings in the last appointment and tells you to follow up with a specialist. She creates such a well-written report for you.... I wish I could continue seeing her but she just does the testing.I heard that other doctors in here are good as well. I HIGHLY RECOMMEND this place.
