Welcome to Our Practice

Information Regarding COVID-19 & Our Practice

Long Beach Gastroenterology will be making every attempt to service our patients during the coronavirus pandemic. We continue to monitor the situation closely and for the safety of our patients, staff, and physicians, we will follow all guidelines from both the government agencies and our medical organizations and societies. 

With that in mind, we have made the following adjustments for the foreseeable future:                               

     1. Limit office visits unless medically necessary                                                                                           

     2. Maximize the use of phone and video visits, details below                                                                       

     3. Defer all elective procedures (endoscopy and colonoscopy) for at least the next few months                 

     4. Continue to schedule more urgent procedures at the outpatient surgery center, which continues to operate, but on a limited basis. 

We appreciate everyone's understanding and patience, and to the best that we can during this pandemic, remain committed  to providing the quality care that has been the hallmark of our group's practice for nearly 40 years. 

Thank you.
