Dr. Ballas is a radiation oncologist at Keck Medicine of USC, who specializes in providing exceptional cancer care, using state-of-the-art radiation technology.

Here’s what you won’t find on her resume.

Family means a great deal to her.

“My husband and daughter are the world to me. When I’m not at work, I spend my time with them, going to the movies, baking or trying new foods and restaurants. We also love to travel, and my favorite place to visit is Blackberry Farm in Tennessee.”

There’s a surprising truth about her.

“Even though I grew up in Wisconsin, I don’t like the Green Bay Packers or cheese.”

She has a passion for the culinary arts.

“If I could trade careers with anyone in the world, I would love to be a pastry chef.”

Medicine has deep roots in her family’s history.

“My dad is a urologist, and my grandfather was an internist. Following in their footsteps was a natural career choice for me.”

Her patients are the best part of her job.

“Getting to know my patients and their families is the most rewarding part of what I do. Being involved in their lives at a critical time creates a bond between us that I find incredibly rewarding. I find meaning in helping treat my patients’ cancer and in alleviating their cancer-related pain.”

Technology has revolutionized her practice.

“Radiation oncology uses a lot of sophisticated technologies. Now we can give more focused treatment for many cancers without as many side effects.”

Keck Medicine is a special place for patients and physicians alike.

“I love academic medicine. It allows me to spend time investigating research questions that I’m passionate about while also mentoring medical students and helping them discover what kind of physicians they want to become. Through my work I’m also able to interact with various types of patients. Keck Medicine provides me opportunities in all of these areas and invests in its faculty’s success — just as it invests in the success of its patients.”
