Beginning sometime prior to 2015, Jack knew he was not well however, the cause was not diagnosed until 2016. It began as myeloma, mutating to myeloid leukemia with several subsequent mutations. In July of 2018 Jack underwent a bone marrow transplant. The transplant was successful for about 4 months, after which another mutation occurred. He was put on a newly released targeted drug and it put the leukemia into remission for about 2 years. After that time, once again, the leukemia mutated. He was given more chemotherapy with moderate success. He was accepted into a clnical trial in April at MD Anderson and was hopeful for the future. Throughout the seven years of treatments Jack received many donor platelets to help his body fight. He fell April 17th. The fall caused a subdural hematoma from which he even with donor platelets, couldn’t fight. His long and valient struggle ended. We are at peace knowing he is finally able to rest.  

Over the last seven years the many nurses, doctors, and staff at OU Medical Center, Stephenson Cancer Center, and his transplant team provided excellent care above and beyond what was required of them. There are not enough words to express our gratitude to them and the supurb care Jack received. 

During the course of his treatment, Jack received many infusions at the blood infusion clinic, O’Donaghue Bldg. at OU. Our upmost graititude is extended to the nurses in the clinic for their personable, dedicated and compassionate care over the years.

To the Oklahoma Blood Institute and their many generous blood donors who provided a plethora of blood products for Jack over the course of his struggle with leukimia, we are so thankful for each and every unnamed person who donated the products he received. Without the infuesd blood products he would not have been able to fight for so long. 

The family requests in lieu of flowers, those wishing to honor and remember Jack, should donate to the following medical services he used. Designated donation to: Bone Marrow Transplant through OU Health –!/donation/checkout or Designated Donation to: Research through Stevenson Cancer Center –
