  “I establish a comprehensive understanding of each patient as a person as well as the patient’s medical needs. My compassionate and focused approach enables me to select the most appropriate treatment for managing the disease. Having a positive relationship with my patients as their treating physician is of great importance to me, and I make every effort to offer the most up-to-date treatment. Teamwork is essential; therefore, I confer with physicians in medical oncology and other specialties as needed with the goal of optimizing patient care.” Consult-Catalya
