Welcome to Our Practice

The Gastroenterology office of Drs. S. Zamani and C. Mullen  

At our practice, we believe that each patient and doctor become a team for treating an individual's digestive problems. Our Walnut Creek gastroenterologists spend most of their time listening to understand your concerns and responding with the best treatment options for you. With the help of our professional staff, they also follow up to make sure that problems are resolved and your health improves.

We want our patients to be informed about their digestive problems and treatments, because informed patients make better decisions about their health and well being. That is why we've included a section on this website covering common topics associated with gastroenterology and endoscopic procedures. We encourage you to look through these pages whenever you have an interest or concern related to your digestive health.

We also know that convenience is important to your selection of a gastroenterologist in Walnut Creek. In these web pages you'll find information about our office, including our location, maps, directions, hours, insurance policies and appointment scheduling. Please feel free to contact us with any questions you have or to request an appointment. We hope you find our practice offers the accessibility and personal commitment you look for from a gastroenterologist in Walnut Creek.

To achieve the above goals, we have designed quality care initiatives to accommodate our patients. Our Gastroenterologists continue to offer the most current and advanced gastrointestinal services and highest standards of patient care.
