“My goals are to earn your confidence, help you understand the risks and benefits of treatment, and support you in achieving the best possible quality of life.”
— Dr. Oliveira
Why did you become a physician?

I was born and raised in the mountains of Brazil. For many years, my dream was to become a marine biologist because I was fascinated by the ocean. But when I was 16, my niece was diagnosed with acute lymphoblastic leukemia (ALL). About a year and half later, she passed away. It was a very hard time for me and my family. In the aftermath of her death, I realized I wanted to change my career plans and become a doctor. Since then, I’ve practiced hematology-oncology in both the United States and Brazil. Early on in my training, I studied bone marrow transplantation at Fred Hutchinson Cancer Research Center and went on to help establish a bone marrow transplant unit in a hospital outside São Paulo, Brazil. Joining the team at SCCA, Fred Hutch’s cancer care partner, brings my career full circle. I have so many good memories of working with patients, and I look forward to making more.

How do you approach care?

One of the aspects I enjoy most about being an oncologist is the time I get to spend with my patients. I like to begin my office visits by learning about you and your family. I strive to create a safe, non-judgmental environment where you feel comfortable sharing your thoughts and concerns with me. My goals are to earn your confidence, help you understand the risks and benefits of treatment, and support you in achieving the best possible quality of life.

Provider background

Specialty: Medical Oncology

General hematology-oncology

I am a board-certified medical oncologist, and I treat patients with a variety of cancers and benign hematological (blood-related) diseases. My background includes more than 20 years of experience seeing patients in private practice and hospital settings. Throughout my career, I have also served as a principal investigator for clinical trials of new drug therapies for cancer and other conditions. Currently, I provide care at SCCA Peninsula and other SCCA regional community sites.

Clinical trials

We make promising new treatments available to you through studies called clinical trials led by SCCA doctors. Many of these trials at SCCA have led to FDA-approved treatments and have improved standards of care globally. Together, you and your doctor can decide if a study is right for you.


Many of our SCCA physicians conduct ongoing research to improve standards of patient care. Their work is evaluated by other physicians and selected for publication to the United States National Library of Medicine, the largest medical library in the world.

Your team includes doctors, a team coordinator, a registered nurse, an advanced practice provider and others, based on your needs.
