Patient Care Philosophy

I treat patients with an array of kidney diseases. I have a special interest in managing kidney stones. I take time to connect with my patients. I believe in providing personalized care for each patient that balances their ideals, needs and values with the most up-to-date evidence-based treatment. To provide the best possible patient-centered care, I spend time listening to patients' stories and ensuring I understand their goals and fears.
