Our Practice
VIDA was established by Dr. Robert Armstrong in 1971. Since then, the practice has only grown, and now includes Drs. Sumit Majumder, Rachana Palnitkar & Krupa Karnik. Dr. Robert Armstrong passed away in 2014.
Dr. Armstrong's vision was always to provide the best possible infectious disease care to the bay area residents by recruiting and further training highly accomplished ID physicians. VIDA doctors consult at Good Samaritan Hospital and El Camino Hospital (Los Gatos). Drs. Armstrong, Majumder and Palnitkar have all previously served as volunteer faculty at Santa Clara Valley Medical Center and place high emphasis on research and evidence-based medicine. Dr. Karnik was associated with the Univ. of Pittsburg before starting at VIDA.
