Program Director
Nurse Practitioner

Deb took over as Program Director and Nurse Practitioner in August 2021. She is the case manager of all of our comprehensive care patients and brings many years of experience in pain control, symptom management, education, counseling, and support to patients and families facing any stage of life-threatening illness.

Rev. Linda Simmons, MDiv
Rev. Linda Simmons is the minister of the Unitarian Universalist Meeting House on Nantucket and has served as the volunteer chaplain on PASCON’s Interdisciplinary Team since September of 2014. In her role as chaplain, Linda is available to all of our patients and families as a spiritual support and a compassionate listener. The role of chaplain does not take the place of a person’s clergyperson; it simply provides a non-denominational additional supportive presence to those who’d like one.
Prior to entering the ministry, Linda held a variety of positions in adult and secondary education, and was the senior manager for a program in New Hampshire for 12 years that worked with at risk youth. She attended The New Seminary in New York City and graduated from the University of New Hampshire with a B.A. in economics and a minor in philosophy.
Linda graduated from Harvard Divinity School in May, 2013. Her settled ministry at the Unitarian Universalist Meeting House on 11 Orange St began at the end of July, 2013.
