ST. JOHNS COUNTY, Fla. -- In a field of five brothers, Mary Kate Truss has grown up knowing how to stand out.
"It's really fun. I mean, at first when I was like seven, I was like I would love a sister anytime," she joked.
The 18-year-old senior at Bishop Kenny High School is as devoted to her studies as she is volunteering.
She maintains a high grade point average while also holding down a job and babysitting.
But all of her volunteer work did not really get started for her until after a back surgery when she was younger.
Truss said, "All the nurses there were so great, and I was like if I can get through this surgery, I can give back to others."
From then on, she did just that.
Truss volunteers at the Mandarin Food Bank. She traveled to Haiti on a mission trip to help an orphanage after the earthquake. That trip is also when she made a big life decision.
