Our Team

A transplant requires a multidisciplinary approach. At UR Medicine, we have a team of transplant specialists from many areas of healthcare.

We focus on treating the whole patient—and that means giving you a team that is ready to care for all your needs—physical, mental and emotional.

The members of our team communicate regularly to ensure each specialist is informed about your condition and treatment. We get everyone’s input to make the best decisions for you.
