Welcome to Stem Wellness! My name is Stella Stempel, and I am a Licensed Clinical Social Worker and a Psychologist. In over 10 years of private practice, I worked with individuals, couples, and families. My approach is consistent, incremental change coupled with healthy thoughts that leads to a more satisfying life. Changing the way we act affects the way we feel and the way we view ourselves. When working with me, you are guided towards intentional living and healthy thought processes.

I’m a board-certified Psychiatric-Mental Health Nurse Practitioner with a background in both medical and behavioral health care. My approach is collaborative, compassionate, and grounded in real-world experience—helping clients feel understood while working together toward meaningful change.

My professional journey has included years of practice across inpatient, community, and outpatient settings, where I’ve supported individuals and families navigating mental health challenges, substance use recovery, and life transitions. I value creating a safe, nonjudgmental space where clients can explore their goals and develop strategies for wellness and resilience.

I believe effective care blends clinical knowledge with empathy, respect, and open communication. My goal is to meet you where you are, honor your unique story, and help you move toward a more balanced and fulfilling life.
