Dear South Bay Gastroenterology patients,

Our thoughts are with our patients, their loved ones, and our entire South Bay community during this unprecedented time. We would like to share our support as well as updates on SBGI’s response to the Coronavirus (COVID-19) pandemic. The safety and well-being of the community are of the utmost importance to us, and we are vigilantly monitoring and evaluating this evolving situation. In light of concerns around COVID-19 and the recommendations and guidance of numerous agencies, we have elected to pre-emptively suspend all non-urgent office consultations and outpatient procedures. The office will remain open for urgent consultations only, and all non-urgent follow-ups will be served via Telehealth or be rescheduled. We will continue to provide hospital coverage for our inpatient population at both Torrance Memorial Medical Center and Providence Little Company of Mary Medical Center. SBGI has been in daily communications with both hospital leadership teams in our unified effort to curtail the spread of this virus. We will provide additional updates in the coming weeks to inform you about any changes to public and practice policies. As COVID-19 continues to spread throughout our country, the health and safety of our patients, healthcare providers, and employees is a top priority for South Bay Gastroenterology. We regret any inconvenience this may cause to your schedule and look forward to continuing to serve your healthcare needs.

Please submit any questions via our website and we will get back to you as soon as possible.
