Get to know Infectious Disease Specialist Dr. Jose G. Montoya, who serves patients in Palo Alto, California.
Dr. Montoya is an infectious disease specialist and researcher noted for his expertise in toxoplasmosis, infection as a trigger of chronic unexplained syndromes, chronic fatigue syndrome, myalgic encephalomyelitis, long COVID, and infection in patients with compromised or abnormal immune systems.
Considered an international authority on toxoplasmosis, he is currently the Director of the National Reference Laboratory for the Diagnosis and Treatment of Toxoplasmosis, the “Dr. Jack S. Remington Laboratory for Specialty Diagnostics (Remington Lab)” at Palo Alto Medical Foundation.
In 2020, under the vision and leadership of Dr. Montoya, the Remington Lab joined the diagnostic efforts to fight the COVID-19 pandemic by enhancing the lab’s capacity to COVID-19 serologies and PCR testing in nasopharyngeal swabs. The Remington Lab contributed to Sutter COVID diagnostic efforts with more than 20,000 PCR tests per month. The Remington lab also led a study on SARS-CoV-2 IgG responses following immunization with mRNA vaccines in Palo Alto Medical Group clinicians.
Doctor Montoya’s current research interests focus on diagnosis and management of toxoplasmosis in the setting of pregnancy, neonatal and infant period, childhood and adolescence, eye disease, and severe disease in immunocompetent and immunocompromised patients. Dr. Montoya also continues his research efforts in unveiling the pathogenesis of and treatment options for post-acute infection syndromes.
Originally from Cali, Colombia, Dr. Montoya completed his Medical Degree with honors at the Universidad del Valle. He then trained in internal medicine at Tulane University in New Orleans. Following his residency, he completed his fellowship in infectious diseases at Stanford University in Palo Alto under the mentorship of Drs. Jack S. Remington and Thomas C. Merigan.
Thereafter, Dr. Montoya had the unique opportunity of having been chosen by Dr. Jack S. Remington for an additional seven years of extended fellowship/training on toxoplasmosis and immune responses against intracellular pathogens at the Department of Immunology and Infectious Diseases at Palo Alto Medical Foundation.
Dedicated to his speciality, Dr. Montoya is board certified in infectious diseases by the American Board of Internal Medicine.
In recognition of his commitment to the internal medicine community, Dr. Montoya was elected Fellow of the American College of Physicians (FACP). He has also achieved professional excellence in the field of infectious diseases, having been named Fellow of the Infectious Diseases Society of America. On a professional level, he is an active member of the American Association for the Advancement of Science, American Society for Microbiology, American College of Physicians, American Medical Association, and Infectious Diseases Society of America.
He has published more than 200 articles and book chapters in peer review journals and books. During his residency at Tulane and tenure at Stanford University, Dr. Montoya received 14 school-wide teaching awards. During his 29 years at Stanford, he initiated, participated in, executed, and led more than 30 clinical trials and founded the Infectious Diseases Immunocompromised Host Service in 2001 and the ME/CFS program in 2007.
