Renee Crizer, PhD, RN, FNP
Wellness Warriors
Rooted in a deep faith in God that guides every aspect of her life and practice, Renee has always felt called to care for those who are suffering. Her journey in healthcare began early as she cared for her father through brain cancer and supported other family members during illness. These experiences shaped her compassion and led her to pursue nursing, earning her RN, then her PhD, and later a Certificate of Advanced Graduate Studies as a Family Nurse Practitioner.
While her faith remains her highest priority, Renee also pursues a strong calling to teach. She is dedicated to educating nursing students and helping them integrate empathy, humanity, and purpose into their practice…just as her faith inspires her to do each day.

Brittany Sierra
Outreach
Brittany Sierra encountered Jesus at 21, a moment that transformed her life forever. What began as a small seed of faith grew into a deep, daily friendship with God.

Brittany’s life now reflects the grace, patience, and forgiveness that Jesus showed her, and her passion is to share that same love with others. She believes that “love covers a multitude of sins”—including her own—and delights in helping others discover that nothing can separate them from the love of God. Romans 8:38–39
