What is FIT Together?

FIT [Functional Improvement after Treatment] Together is a 501(c)(3) nonprofit organization founded in 2014 under the leadership of Dr. Kerri Winters-Stone and Jessica Sitemba.

The mission of FIT Together is to provide evidence-based, professionally led, group exercise classes specifically designed to meet the abilities, needs and goals of people who have cancer, have had cancer, or have been treated for cancer.




Co-founder and President

Kerri Winters-Stone 


Committed to ensuring that people with cancer can join exercise classes that are proven beneficial, safe, and accessible, Kerri started FIT Together in 2014 with co-founder Jessica. She has a PhD in Human Performance and has been conducting research in exercise oncology for 20 years. She has run over 15 clinical trials funded by NIH and cancer non-profits and she co-wrote the current American College of Sports Medicine exercise guidelines for cancer survivors. This expertise and passion to bring science to practice is what led to FIT Together. Seeing how FITT changes the lives of people with cancer is the most rewarding part of her career.
