Dr. Dwadasi grew up in Kokomo, a small town in Indiana. When she is not working, she enjoys spending time with her family and friends, watching TV, running and dancing. Being relatively new to Austin, Dr. Dwadasi is looking forward to exploring the area.
I was always drawn to the field of science/medicine while growing up. During medical school, I did a rotation in Gastroenterology and really enjoyed it. I have a special interest in Inflammatory Bowel Disease (IBD) because it is complex, affords continuity of care with patients, and is an area of growing research. I want to make sure I understand my patients’ medical history, but most importantly, I listen to their concerns and why they are coming for care. I want to ensure we both have a good understanding of the care plan that we reach together.
