Dr. Dana D. Portenier

I have the privilege of treating patients with both benign and malignant conditions of the chest. While in college at Georgia Tech, I envisioned a career as a biomedical engineer. What I quickly learned, however, was that I was more interested in patients and their medical problems than developing the technology to care for them. During my medical education and training, I learned not only how to become a surgeon, but also learned the value of teamwork and family in caring for patients. As a thoracic surgeon, one of the best and most important aspects of my job is being able to establish a relationship with my patients and their families, working together to help them through their illness.
