Sydney Karahalios MSN, RN, PMHNP-BC

Instructor

At the heart of my work is a deep love for teaching, mentorship, and the meaningful relationships that grow through both. I’m passionate about weaving together faith, the art and practice of nursing, psychology, and philosophy to help students think deeply, care well, and lead with compassion. The field of mental health and psychiatry has always felt like sacred ground to me. It is a space where presence, curiosity, and connection can bring true healing, and I've always felt privileged to be a part of that process. Whether in the classroom or in clinical practice, I find joy in walking alongside students as they grow not just in knowledge, but in purpose and heart.
