Tariq Ahmad, MD

HS Clinical Professor
Pediatrics

I primarily provide clinical care on both the Oakland and San Ramon campuses for both diabetes and endocrine care. My clinical research is focused on type 1 and type 2 diabetes., though I'm also part of the Northern California Comprehensive Thalassemia Center allowing me to investigate endocrinopathies in this cohort as well. Our UCSF site serves as one of the few centers of excellence for this condition in North America. Since diabetes camps have served as the reason for me pursue pediatric endocrinology, I have been part of the medical staff at summer diabetes camps since 2000.

Madhav Vissa

Pediatric Hematologist-Oncologist
Pediatrics

I am a pediatric hematologist with a special interest in caring for individuals with inherited blood disorders, specifically sickle cell disease and thalassemia, throughout the lifespan. Before my fellowship training in pediatric hematology/oncology, I completed a residency in combined internal medicine and pediatrics with the goal of providing specialty care for individuals with lifelong medical conditions. My overarching goal is to ensure patients who live with chronic conditions are able to thrive as healthy, functional children, adolescents and adults.
