Who We Are

About Us

Mesquite Gastroenterology and Surgery Center (MGSC) was founded in 2009 by Dr. Miguel A Arenas. MGSC is an outpatient procedure facility, built to provide our patients the latest technology in endoscopy and the highest level of service.  Having an on-site surgery center enables us to perform these outpatient procedures in the comfort and security of our offices. Our nurses have extensive gastroenterology experience, and along with the rest of our staff, we offer the most convenient and comfortable care in the city.

With over 30 years of combined experience in Gastroenterology and Internal Medicine, the board certified specialists of Mesquite Gastroenterology and Surgery Center (MGSC) are recognized as principal leaders in digestive health in Tucson. This experience, combined with our state-of-the art office and surgery center, bilingual staff and doctors, enable us to offer the best patient care in Tucson.

We invite you to explore this website to learn more about Gastroenterology, our practice, policies and procedures. Since you and your family’s health are our primary focus, we invite you to call our office for more information, to schedule an appointment or to speak with our (Patient Care Coordinator).

Mission

Our mission is simple – to provide the highest level of gastroenterology care and treatment of digestive diseases, in a friendly, safe, state of the art, immaculate environment by highly skilled and compassionate professionals. Staffed by top gastroenterologists and supported by a team of specialty trained nurses and technicians, we are dedicated to providing comprehensive care while respecting your time and privacy in the most cost-effective way.

Specialized Care

Our physicians are certified to perform all gastrointestinal procedures and have established a reputation for excellence in endoscopy – a procedure enabling the doctor to look inside the digestive track. We stay up-to-date on new technologies and advancements in medicine. With colon cancer being the third most common cancer of men and women in the U.S., we also have a special interest in colon cancer screening. Preventative care is essential and we are here to help.
