General Surgery

Comprehensive Surgical Care

Stephenville Medical & Surgical Clinic (SMSC) provides general surgery services for patients who need surgical evaluation and treatment for a wide range of conditions. Our board-trained surgeons offer traditional, laparoscopic, robotic-assisted, and endoscopic procedures. They treat abdominal and gastrointestinal conditions, hernias, colorectal disorders, and certain cancers, and they provide fast, coordinated care for urgent and emergency surgical needs. 

Our general surgery team cares for you from the first evaluation through postoperative follow-up. We emphasize individualized treatment, clear communication, and continuity of care. Our surgeons partner with patients and families to explain treatment options, set realistic expectations, and make sure you know what to expect at every step of the surgical process.
