Ally Medical Emergency Room, a leading provider of freestanding emergency medical care facilities across Texas, proudly announces the opening of its newest location in San Marcos at 2810 South I-35 Frontage Road in San Marcos.
The San Marcos facility marks Ally Medical ER’s ninth emergency room in Texas since its founding in 2016, underscoring the company’s continued commitment to expanding access to timely, high-quality emergency care in local communities. Freestanding emergency rooms provide a convenient and efficient alternative to traditional hospital ERs — delivering the same full range of emergency services but without the long wait times often associated with hospitals.
“Ally is thrilled to begin serving the San Marcos community,” said Emmanuel Colliot, CEO of Ally Medical Emergency Room. “Our mission is to provide compassionate, high-quality emergency care — with less waiting and more personal attention. We believe every patient deserves more than just prompt treatment; they deserve to be seen, heard and cared for with empathy and excellence.”
The new Ally Medical ER in San Marcos is physician- owned and staffed 24/7 by board-certified emergency physicians and highly trained clinical teams. The 6,500-squarefoot facility includes seven exam rooms, with space to add three more and is equipped with advanced diagnostic imaging capabilities including CT scans, X-rays and ultrasounds. If a patient requires hospital admission after being diagnosed and stabilized, Ally Medical ER coordinates all necessary transportation and transfer logistics to a nearby hospital.
Key Features of the New San Marcos Facility:
• 24/7 Access – Open every day, around the clock.
• Minimal Wait Times – Designed for efficiency and fast treatment.
• Expert Medical Team – Board-certified emergency physicians and skilled clinical staff on-site.
• Advanced Diagnostics – On-site CT scanner, X-ray and ultrasound capabilities.
• Convenient Location – Easily accessible off I-35 in San Marcos.
Ally Medical ER thanks Holland & Knight for providing legal counsel throughout the facility opening and related transactions.
