Dr. Creasy became a surgical oncologist so he could help patients gain insight into their disease, provide exceptional surgical care, and walk with them during a difficult and vulnerable time. 

Dr. Creasy completed his residency in general surgery at Weill Cornell Medicine- New York Presbyterian Hospital in New York, NY. He received additional fellowship training in Surgical Oncology and Hepatopancreatobiliary (HPB) surgery at Duke University in Durham, North Carolina. During that time, he gained broad exposure to oncologic procedures and principles and multi-disciplinary care of cancer patients. That experience, combined with understanding the patient’s unique goals and priorities, facilitates his ability to integrate and manage all components of a patient’s cancer care. Dr. Creasy also gained specialized training in HPB diseases and minimally invasive and robotic surgery, which are his areas of clinical and research interest.

Dr. Creasy enjoys listening to patients and learning about their background and experiences. He seeks to partner with patients and their families to develop treatment plans that align with their goals. He is particularly thankful for the relationship that develops between a surgeon and patient over multiple visits and years. He believes multi-disciplinary patient care requires camaraderie and mutual respect with colleagues and other specialties. As a surgeon at The Oregon Clinic, Dr. Creasy has the privilege to work alongside a team of caring and talented support staff to provide an excellent experience, personalized care, and the best outcomes for patients. He is also honored to be involved with education in the fellowship training of young surgeons.

As a transplant to the Pacific Northwest, Dr. Creasy and his family are excited to live in Portland and combine a culturally robust city with the awe-inspiring natural beauty of Oregon. He is thankful that Portland offers great neighborhoods, local restaurants and breweries, and accessibility to nearby forests and national parks. Outside of the hospital, Dr. Creasy enjoys hiking and camping with his wife and three children. He also likes reading, history, barbecue, college football, and his kids’ sports teams.
