This medical center seems to have a good location and convenient working hours, but the quality of service can be inconsistent. Some patients praise Dr. Zhang's knowledge and kindness, while others have had negative experiences, including feeling rushed, receiving outdated advice, and being treated poorly. The office staff seems to be responsive, but some patients have reported difficulties with billing and payment issues. The center's accessibility features, such as wheelchair-accessible parking and restrooms, are a plus. However, the main issue that stands out is the problem with Dr. Zhang's bedside manner and the office's handling of payment and prescription issues. A patient was forced to pay a large sum out of pocket or risk not receiving medication, which raises concerns about the center's ethics and patient care.
