Our Team

At the Bladder Cancer Center, our team of expert specialists uses a multidisciplinary approach to treat bladder cancer that is coordinated and seamless. Along with offering minimally invasive surgical options, we provide oncology services in conjunction with Dana-Farber Community Cancer Care at St. Elizabeth’s Medical Center. 

Every patient meets with a team consisting of a urological surgeon, urological oncologists, radiation oncologists, hematology oncologists, social workers and nutritionists to create a personalized treatment plan. In addition, patients are assigned to a nurse navigator who is an experienced registered nurse with special expertise and experience in cancer care, and provides guidance support throughout all stages of care.
