Where I practice
About me
I am thrilled to join the team at Kaiser Permanente as an endocrinologist, where we have a team of providers, including diabetes educators, nurse practitioners, and physician assistants, dedicated to delivering high-quality care. Together, we work as a team with a shared focus on what truly matters — our members.
Biography
The seed for my medical journey was sown by my sister, whose influence and encouragement inspired me to pursue a career in medicine. I began my training in India and later completed my endocrinology fellowship at Tufts Medical Center in the United States. My mentors, peers, and members have shaped me into the physician I am today, and I am deeply grateful for the lessons I have learned from them. Having worked in private, hospital-based, and academic settings, I bring these diverse experiences to my practice.
About my practice
I have a special interest in thyroid disorders and thyroid cancer and am committed to providing personalized, tailored care to each member. I believe in fostering strong relationships to empower you in your health journey.
How I thrive
Outside of work, I enjoy walking my dog, running, spending quality time with my kids when they are home from college, and engaging in stimulating conversations with them. I value family time and believe that maintaining a balance between work and personal life is essential for overall well-being.
I am excited to be part of Kaiser Permanente’s mission to deliver high-quality care and look forward to making a meaningful difference in the lives of members
