Urgent Care and Other Medical Services From Experienced Practitioners

When visiting an urgent care center becomes necessary, finding a reliable walk-in clinic that can quickly meet your medical needs is often easier said than done. Designed to bridge the gap between pricey emergency rooms and primary care physicians with week-long waits, Affinity Urgent Care’s clinics are one-stop shops for comprehensive diagnostics and immediate medical treatment. With three convenient locations in Alvin, Galveston, and La Marque, Texas, receiving same-day medical attention is as simple as finding the urgent care location nearest you.

"We have a special needs daughter who needed her foot looked at. Thankful that Affinity accepted her Medicaid first of all. Staff was nice, did not have a long wait, doctor was knowledgeable and understanding with our daughter, which means a lot. She was able to get x-rays done on her foot and received the results before we left. A great place to go on short notice."
"Facility was very clean. Very short wait. The doctor and x-ray tech were great!!"
"Fast and friendly. Was in and out in about an hour, and the PA and nurses were great. Much better experience than the ER."
"The Affinity care clinic in Galveston was wonderful. I walked in Memorial Day (without an appointment) and was seen by a very courteous and helpful staff. I highly recommend them."
"My experience at this urgent care facility was a pleasant one. I brought my daughter in due to an allergic reaction. The staff members there were awesome!"
