APPOINTMENTS
We respect our patients' time and pride ourselves in creating as fluid and convenient of a patient experience as possible without sacrificing quality of care. As such, patients are seen by appointment only. We do set aside a few same-day appoint-ments for our sick patients. Sick patients needing to be seen must call ahead to be scheduled for a same-day (or sometimes next-day) appointment based on availability.
eMERGENCIES
AND AFTER HOURS
In the event of a life-threatening emergency, always dial 911. If you or your loved one become ill during business hours, please call our office first as we reserve same-day appointments to see you if you become ill.
When the office is closed after office hours or on holidays, please call 956-412-2836 and an on-call physician will be contacted.
pATIENT PORTAL

PRESCRIPTIONS
A new prescription usually requires an office visit. The turnaround time for prescription refills is 72 business hours, but some medications have specific requirements which is why we strongly recommend prescription refills be requested one week prior to your last medication dose.
