Advocating for medically fragile kiddos and their families since 2017

The Be Fierce Foundation was created in 2017 to serve as an advocate for kids and their families that are fighting rare and undiagnosed diseases. 

This foundation was borne from the love of a family for their own warrior princess, Aubrey Kyne. Aubrey graced this earth for a short four years but in that time she had a huge impact on those that had the honor of being part of her life. Aubrey was medically fragile and had a lifetime of health challenges, but she was also a silly, vocal, and beautiful little girl that loved life.

She taught us how to stare into the face of uncertainty and smile back. The Be Fierce Foundation is a way to honor her legacy and give back to a community that is experiencing emotional and physical challenges that most of us can only imagine.

Community Support 

Be Fierce is a voice in the community for kids and families who are relentless in their fight against rare and diagnosed childhood diseases. We look to partner with others — individuals or nonprofits — who are as passionate as we are about creating a community of support, acceptance and compassion.  Look for ways you can get involved on the About page.


Being fierce is a labor of love and with that in mind, all funds raised will be used to support the fierce community in the form of creating care packages, securing grants for families battling rare or undiagnosed diseases, donating to other organizations that support the community, and conducting other charitable events.

Care packages 

We prepare care packages for children and their parents that are battling rare and undiagnosed diseases. These care packages aim to bring a little fun and joy to challenging times and to help make life just a little bit easier for fierce families.Check our out About page to learn how you can help us secure supplies or put together packages.                    


From writing letters to local and state officials about the needs of the medically fragile to working with health professionals to secure necessary medical equipment, the team members at Be Fierce are no strangers to advocating for the special needs community. If there’s a cause that needs our support and services, use the form below to connect with our team.


Our team is a resource to help families secure grants and pay for things such as accommodations during hospital stays, durable medical equipment and medical items that are necessary but not covered by health insurance. If you would like to apply for one of these grants please use the “Let’s Connect” section of the website below to reach out to the team.                                     


One pillar of Be Fierce’s vision is to provide families with resources to navigate the uncertainty that comes with fighting rare and undiagnosed childhood diseases. As our organization grows, we plan to publish content and draw on the experience of others who have experienced firsthand the complexities that come with battling rare diseases.


And though she be but little, she is FIERCE.
