About Me

Cancer care teams use more methods and tools than in the past, and you can turn to Sydney Strait, CGC, a genetic counselor who practices at Avera Cancer Institute in Sioux Falls, SD.

Insightful Genetic Information

Strait can help patients of all ages, and she works in collaboration with the physicians, specialists and technicians who make up the Avera Cancer Institute team. She meets with patients to help them understand how genetics and family history can play roles in their health.

Cancer Genetic Testing and Counseling

Strait recommends that anyone with a personal or family history of cancer discuss their risk with their provider, who can make a referral when indicated. “I enjoy getting to know my patients and helping them understand how genetics can play a role in their risk for cancer, talking them through a difficult situation, or helping them work through a decision about genetic testing. I do this by getting to know my patient and respecting their values and needs.”

Avera is a leader in the use of new, leading-edge approaches to help people who face cancer. We can use genetic insight to approach cancer in ways that were not possible even five years ago. Information is powerful – and can be a powerful source of inspiration for patients and their families.

Active Lifestyle

When not working with patients and professionals at Avera Cancer Institute, Strait enjoys spending time with family and friends, watching movies and being creative.
