Ulysses S. Rosas, MD
Specialties
- Gastroenterology
- Internal Medicine
As a child, he was heavily influenced by a local orthopedic surgeon, Dr. Robert Sullivan. “Through the care and compassion Dr. Sullivan showed me as a patient, and later on through his mentorship, I knew I wanted to become a doctor,” states Dr. Rosas.
Dr. Rosas’ research and clinical experiences during medical school lead him to specialize in gastroenterology. “The field of gastroenterology provides a great mix of patient interactions and clinical experiences. Including providing preventative healthcare, managing both chronic and acute diseases, and making therapeutic changes through various endoscopic procedures.”
With a patient-centered approach, Dr. Rosas strives to understand not only his patient’s medical diagnosis, but also how their GI health affects their quality of life. By building a trusting relationship with patients, Dr. Rosas is able to get patients back to living their best lives.
