Dave Sandersfeld, a retired John Day Fossil Beds National Monument ranger, and his wife, Debbie, are raising money to fight his stage 4 colon cancer.

A donation account has been set up at the Old West Credit Union under the name Dave Sandersfeld.

Without treatment, he is expected to live two to three months and with treatment he may have two to three years. His treatment will require travel to Bend every other week.

He is using medical marijuana and his own personal knowledge of herbs to help combat the cancer as well as working with Chinese medicine practitioner Kyle Cline.

“Prayers are needed for sure,” Debbie wrote in an email. “With hope and prayers we look forward to beating this and getting the surgery to remove the cancer in his kidney.”
