Jonathan was diagnosed with kidney and prostate cancer in November, 2013. While his kidney cancer went into remission during the fall of 2014, the prostate cancer was a much stronger foe. Since its onset, Jonathan was in constant treatment including surgery, radiation and anti-hormone therapy, followed by additional radiation, chemotherap and ongoing anti-hormone therapy to treat metastatic prostate cancer beginning in 2016.
In May 2018 a new, relatively sizeable prostate cancer mass was identified in his former prostate bed. Unable to remove surgically or treat with radiation, the palliative option for treatment included new rounds of chemotherapy treatments from June through September 2018, followed by cryogenic surgery. After a five year courageous battle, fighting the cancer with all his might, Jonathan sadly lost that battle on March 27, 2019.
Throughout his journey Jonathan was bolstered by remaining actively engaged in the community and his work, hoping as he said to “change the face of cancer.” Having received so much support during their cancer journey, Jonathan and Ginger Zierdt established the JZ Cancer Fund in 2017 with a mission and vision to build community cancer awareness and support and to help change the cancer journey. The JZ Cancer Fund remains committed to fulfilling Jonathan’s vision and legacy.
