Sierra McCahon

Sierra McCahon knew she loved helping others at a young age, and has been volunteering since her days as a student. A recent graduate of the University of Mary Washington, Sierra worked as a Registered Behavior Technician – helping children on the autism spectrum with verbal, social, and communication skills – when she was in school. She now volunteers as a Communications Coordinator and advocate at PAVE: Promoting Awareness, Victim Empowerment. She has seen the impact cancer has had on her family and knew she wanted to dedicate her career to doing something to fight back.

As ZERO’s Operations Assistant, Sierra is on the front lines, talking to men who need assistance, helping volunteers make a difference, and ensuring each family has what they need on their journey. With her Southern charm (she’s from South Carolina) and passion for being a resource for patients, Sierra helps make every day brighter for everyone she comes in contact with.

When she’s not fighting for patients, Sierra is using her other talents to code software, play video games, and expand her extensive comic book collection. Ask her about ZERO’s volunteer awareness toolkits and other ways you can get involved with ZERO here.
