Deb Walker is native to the Cincinnati area. After high school, Deb attended Mount St Joseph University where she graduated with a bachelor’s degree in education.  Deb went on to teach elementary,  junior high and coached high school sports for 6 years.  As she moved into her prehospital career, as paramedic/firefighter she continued to teach EMS and fire to new cadets.  Deb began as a volunteer EMT/firefighter for Rossmoyne Fire Department.  As a paramedic and firefighter, she started her full-time job as a Fire Lieutenant and then Fire Captain for Sycamore Township Fire Department.  After years of service as an Assistant Fire Chief for Hamilton Township Fire Department, Deb retired from the fire service. 

During the firefighting days, she was lucky enough to have a fire chief who had a background in education.  He sent her to Clark State for a bridged nursing class where she graduated in 2011 as an RN.  Having a certification in nursing and paramedic permitted her latitude to be flexible in the workforce and was recruited by a deep-water drilling company in Houston, Texas.  For three years, Deb ran their 3-bed hospital where she was the only medical personnel on board the ship in charge of 197 souls.  Upon her return to the states in 2015, she worked as an RN in the emergency department at UC West Chester hospital.  In 2018, she was welcomed to TriHealth as a full-time EMS Coordinator.  In addition to her role at TriHealth, Deb continues to keep her skills up to date while working part-time at a local EMS department. In her spare time,  Deb visits local hospitals with her two therapy dogs: Bailey and Sadie; they love to round with her when she visits the fire departments and emergency departments.

Carly Nunn is a stroke survivor, educator, and passionate advocate for brain aneurysm and AVM awareness.

Her recovery began relearning the most basic of skills- a journey that deepened her commitment to supporting other survivors and raising awareness about the realities of stroke in young adults.

Today, Carly teaches English as a second language to adults and serves as a board member of the Tri-State Brain Aneurysm Support Group. She is a proud dog mom who cherishes free time with her family and friends. Carly is dedicated to building a more informed and compassionate community through advocacy, education, and survivor support.
