Personal Information

Dr. Mishra is a board-certified gastroenterologist serving the Sarasota and Lakewood Ranch communities. She has a special interest in obesity and nutrition, cancer prevention, esophageal and reflux disorders and women’s health. She completed her internal medicine residency at Medstar Georgetown University Hospital in Washington, DC, then went on to Rutgers Robert Wood Johnson Medical School for her gastroenterology fellowship. Dr. Mishra provides care to patients who struggle with common to complex gastrointestinal and liver diseases.

“Diagnosing gastrointestinal issues can be very nuanced and layered; it requires paying key attention to patients’ symptoms while keeping in mind already diagnosed medical comorbidities. Patients need to know they’re heard and are working with someone that is invested in their care. An essential part of this doctor-patient relationship is continual patient education and engagement. As physicians, we need to constantly be talking to our patients about the importance of understanding symptoms and early screening. With this work, we can save lives.”
