As a Nurse Practitioner and owner-operator with extensive inpatient and outpatient environment experience, I have understood the importance of compassionate and high-quality care for patients and their families. Hospice care and decision making is often challenging, puzzling and guilt-ridden experience for patients and families. My passion to help those in need has been the driving force for my involvement with Advent Hospice Care.

Ted Stefan


As a chaplain at Advent Hospice Care, my primary role is to provide spiritual support and care to patients and their families during end-of-life journeys.

I hold a degree in divinity or a related field, and I have specialized training in hospice and palliative care. My experience working in healthcare settings has given me a deep understanding of the unique emotional and spiritual needs that patients and families face during this challenging time.

In my role, I work closely with patients, families, and healthcare providers to provide compassionate, non-judgmental support that honors each patient's individual beliefs, traditions, and values. I offer comfort, guidance, and prayer for patients and their loved ones, and I work to create a safe, welcoming environment that fosters healing and hope.

I am committed to upholding the values of inclusivity, empathy, and respect in all aspects of my work. I believe that every patient and family deserves to have access to spiritual care that is meaningful and relevant to their unique experiences and beliefs. As a chaplain, I am honored to walk alongside patients and their families during this sacred and transformative time, and to help them find peace, comfort, and solace in the face of life's most difficult challenges.
