Co-Host: Charlie Navarrette

Charlie Navarrette

Charlie started his career as an actor. When it became a strain on young family, he got a job as a paralegal with a legal firm assisting people with Mesothelioma – a lung cancer caused by exposure to asbestos. As patients asked questions, he became studied on issues related to palliative care and death. Charlie lives in New York City, and teaches English as a second language and still gets acting gigs with internet original movies (Netflix and Amazon Prime). Keep an eye out for him!


Executive Producer: David Gillett, Major General, USAF (Retired)

David is retired from the U.S. Air Force after 34 years of service.  He was married for 40 years to his wife, Stacia, who died suddenly in 2017.  He still grieves for her but considers himself twice lucky as he married Dr. Marianne Matzo in 2019.  David is a lifetime runner, a scuba diver, a dedicated Monty Python fan and loves the original Pink Panther series with Peter Sellers.  He has two children: Marcus (married to Heather and grandson Jaxton) and Abby.


Producer: Sandi Troup, BSN, RN

Sandi Troup does our artwork, podcast editing, mixing, website administration, and a wee bit of music as needed.  Sandi had an awakening to the fragility of life as a 32-year old Air Force officer diagnosed with breast cancer.  This experience launched her into a new career as a nurse, and is how she met Marianne.  They worked together in cancer and palliative care research at the University of Oklahoma for over three years.  Shortly afterwards, Sandi and her family moved to Kenya where she was involved in public health programs and child rescue ministries.  When she noticed a decline in her health, their family returned to her stomping grounds in Missouri.  It was there she was diagnosed with a slow-progressing form of ALS (Lou Gehrig’s Disease).  Sandi believes in being grounded in the reality of the diagnosis, while living each moment with tenacity and joy.  In fact, we have a hard time pulling her away from fly fishing, kayaking, music, and finding ways to use technology to defeat declining mobility with her engineering-minded son.  Carpe Diem!


Fantabulous Faith Sister: Nancy Miller

Nancy Miller

Nancy is our spiritual advisor. She has been married to her husband Frank for 6 years and owns and operate Green Acres Farm OKC in east Edmond. She is country girl, grandma to 2, mom to 5, community leader, Founder of the Oklahoma Brain Tumor Foundation, Independent Distributor for Young Living, an ordained Christian Minister, Pastoral Counselor, Chaplain and a Life Coach.  

Nancy’s son Cade was diagnosed with brain cancer at the age of 6 weeks, and died at the age of 14 months.  Her life was torn apart, and she was lost. A year after her son died she and her husband were separated and eventually divorced.  It was at that time when I was in the deepest pit of despair and grief that she found her purpose and calling and started the Oklahoma Brain Tumor Foundation (OKBTF) which she acted as Founder and President for 17 years.

In December of 2016 God called Nancy into full-time ministry and she became ordained and a Certified Christian Counselor.  Additionally, she is a Certified Spiritual Care Disaster provider through the Oklahoma Conference of Churches.

Nancy specializes in grief, trauma and abuse counseling for women.  She has a weekly blog, website and YouTube Channel entitled “Walking with Jesus”.  She also produces weekly devotionals and on-line Bible classes to equip followers of Jesus to full-fill the plans and purposes of God for their life.

Marcia Caplan Friedman

In addition to the love and devotion for her family and friends, Marcia has two other passions in her life – acting and social service.  For her work on stage, she has received two Best Supporting Actress In New England Awards, and several nominations for Best Actress.  One of her most rewarding roles was portraying the wife of a man with Alzheimer’s disease in the Boston premier of Conspiracy of Memory by Steven Bogart.

In her “day job” Marcia has worked at a drug treatment center, shelter for battered women, and for eight years, until her retirement, she was Assistant Program Manager and Program Manager for a Massachusetts Ombudsman Program.  She had 37 nursing facilities in her district where she advocated for nursing home residents ensuring they were not neglected, mistreated or abused, and they received quality care in a safe comfortable environment.  It was very rewarding to know she made a difference in the lives of many.  Marcia loved working with the elderly, and then she became one!

Marcia is grateful for the opportunity to be part of this important discussion of death and dying.
