“I love building relationships with our patients,” says Alyson Greiter, Registered Dietitian in the Outpatient Clinic at Cancer Treatment Centers of America® (CTCA) in Suburban Chicago. “Being part of a Patient-Empowered Care team at CTCA® facilitates a more personal level of contact.”

Greiter earned her Bachelor’s degree in Dietetics at Illinois State University in 2013. She then completed a Dietetic Internship at Bradley University. This training included several clinical rotations that equipped Greiter with a range of tools to provide dietetic support to patients. She worked with dietitians in the intensive care, neonatal intensive care, cancer care, rehabilitation and outpatient care units at Rush-Copley Medical Center. She conducted educational and outreach sessions on nutrition for university students, and developed a corporate wellness program for a Fortune 100 company. She also completed a months-long rotation at a regional cancer center, performing nutritional assessments, developing dietetic plans, and working closely with patients in need of support for cancer along with cardiovascular, renal, gastrointestinal and liver issues.

Greiter has also volunteered her services in several settings, including a school district, a rehabilitation center, and a large medical center.

At CTCA, which she joined in October 2014, Greiter works in the outpatient clinic. She works with patients diagnosed with a variety of cancer types to control symptoms through nutrition therapy. She helps patients handle challenges such as weight gain or loss, swallowing difficulty, and nutrient malabsorption resulting from various treatments. She stays current with research on nutrition support for cancer, and focuses on addressing each patient’s individual needs.

Greiter is a member of the Academy of Nutrition and Dietetics. She is a Licensed Dietitian Nutritionist and a Registered Dietitian.

In addition to her work at CTCA, Greiter also enjoys being outdoors and staying active. She runs half marathons and loves dogs.
