Michele Barmettler, ABM, AGS
Vice President
Michele has been working in health care for 14 years first in home health and then in hospice care. She has been an Office Manager for 10 of those 14 years. Michele has had several experiences with loved ones involved with hospice care and each experience has been different. The biggest lesson she learned is about the quality of life at the end of life. At Endless Journey, Michele loves the community and the attention for the care given not only to the patient but also the family and beyond.
One of the biggest ways Michele would like to see change in the hospice care industry is that all parties and insurance companies should waive deductibles and co-insurance while on hospice. Her goals for Endless Journey are all about Growth and education. This includes buying their new building and acquiring financing for the 12 suite hospice houses.
When Michele isn’t working hard to bring these goals to fruition, you will find her playing a mean game of cards with her family, golfing and enjoying a football game.
