The heart of the medical services is located on the second floor of a building on Martin Street in San Antonio. Visitors need to make appointments in advance. Upon arrival, visitors can use the wheelchair-accessible restroom, parking lot, and entrance. This location is closely related to the Cardiology Clinic at Robert B. Green Campus. The working hours are consistent from Monday to Friday, but it is closed on weekends. Unfortunately, this location doesn't seem to be easily found by walking due to being located on the second floor.
