While she has a solid average rating of 4 out of 5 based on 65 reviews, there is a notable disparity in individual experiences, with some patients expressing dissatisfaction. Many patients appreciate her thoroughness in examinations and her ability to clearly explain health conditions and treatment plans. Specifically, her expertise in managing diabetes and other endocrine disorders is frequently highlighted, with several long-term patients expressing loyalty and satisfaction with her care over the years. However, there are significant criticisms as well. Some patients report issues with the thoroughness of examinations, follow-up care, and the amount of time spent during appointments, rating these aspects lower. Additionally, comments about the attitude of Dr. Joo and her staff vary, with some describing them as rude or abrupt, which has contributed to a lower overall perception of the office environment. Notably, a few patients have mentioned a lack of responsiveness regarding test results, indicating a potential area for improvement in communication and patient care. In summary, prospective patients may find Dr. Joo to be knowledgeable and thorough in her specialty, but they should be aware of mixed reviews regarding her staff's demeanor and follow-up practices. This information could be crucial for individuals considering her for their endocrinology needs.
