5 /5 Rodney Briseño: Scheib center is a mental clinic in San Marcos Tx. I have a family member that goes there and they’re very helpful. Staff is friendly and they do go by scheduling which is good because I don’t ever see people waiting long for their appointments. A plus about Scheib is that they got their own pharmacy called Genoa, which means you don’t have to make another trip to a pharmacy to get your prescriptions.
