Operation Rivco Shield | Diamond Level Certificate | DOHC

Desert Oasis Healthcare COVID Vaccine Efforts Recognized

(June 21, 2021 – Palm Springs, CA)
Dr. Geoffrey Leung and Dr. Shunling Tsang of Riverside University Health System – Public Health visited the Palm Springs campus of Desert Oasis Healthcare (DOHC) to present a Diamond Level Certificate of Achievement for “exceptional achievement in administering over 30,000+ vaccine doses” as a part of Operation RivCo Shield.

“It’s gratifying to have our efforts recognized, not only for the volume of nearly 50,000 vaccines given but also in helping to reach some of the most vulnerable individuals at-risk of being COVID-impacted.”

Dr. Lindsey Valenzuela, PharmD and Associate VP of Population Health Integration

“For months, we’ve been using our Mobile Health Clinic to take the vaccine, as well as a variety of other important healthcare services, directly to people all over the Coachella Valley and the high-desert," Valenzuela said. "Even while masking up and following all necessary COVID safety protocols, the DOHC Mobile Health Clinic has allowed us to restart our health fairs with employer groups, senior centers, and other community events in a new and exciting way.”

Ever since the COVID-19 pandemic hit the U.S., DOHC began regularly updating its members at with online resources from the CDC, as well as from organizations and other government agencies at the state, county, and local levels. When the much-anticipated vaccine arrived in California in December 2020, with DOHC as a designated vaccine provider, those first vaccinated were essential healthcare workers and those living in and working in long-term care settings.

“What a difference those few months have made – not only here in California but in the decrease in the number of COVID cases and deaths across the U.S.,” said Jessica Voigt, MSN, RN and Director of Nursing at DOHC. “Our members and anyone else who visited our ‘Best of Desert 2020’ Immediate Care Clinics could get monoclonal antibody therapy early on, when many others in the desert didn’t have it. It’s been a coordinated and tireless effort of many teams here at DOHC for months, to reach and vaccinate so many in our community. We know that we may not be completely out-of-the-woods yet but getting vaccinated is the way we will END this pandemic.”
