For 3 years she worked closely with the Veteran population in inpatient hospice at the VA Palo Alto Health Care System. She then returned to school to pursue her certification as an Adult/Gerontological Acute Care Nurse Practitioner and Doctor of Nursing Practice Degree from Brandman University while working for Collabria Hospice in Napa, CA. Dr. Ley has been certified in Hospice and Palliative Nursing since 2013 and is dedicated to providing compassionate care and symptom management in advanced illness and end of life care.

Dr. Ley is happy to be living and working in the community that she grew up in. When she’s not at work she loves spending time with family and friends, traveling, running, staying active and playing ball with her dog Buddy.
