Every Alamo City Urgent Care location keeps the same extended hours — Monday through Friday from 8 a.m. to 8 p.m. and Saturdays from 8 a.m. to 5 p.m. — so you can walk in when it fits your schedule, not the other way around. All four clinics accept most major insurance plans and offer on-site labs and X-ray imaging, so most visits are handled start to finish without a referral elsewhere.
