January 16, 1949January 10, 2021

David "Dave" Fronczyk died peacefully at home on January 10, 2021, in Phoenix, Arizona at the age of 71. Dave was born on January 16, 1949, in Chicago, IL to Edward and Josephine. Growing up, Dave enjoyed attending Cubs games at Wrigley Field and was a competitive wrestler in high school. He later served in the Army before returning to school where he earned a bachelor’s degree in Medical Laboratory Sciences from the University of Illinois in 1975. After moving to Phoenix in 1980, Dave welcomed 3 children over the next seven years. He emphasized the importance of education and hard work and, as a result, his children would go on to earn a combined seven college degrees and pursue careers in technology, science, and analytics. Dave’s children remember him as a loving father who was proud of their many accomplishments and who encouraged each of them to pursue their goals, travel the world, and experience the joys of life. Dave was a sports and technology enthusiast, often sharing insights on the latest and greatest electronics with his loved ones. He even built his own computers! With this love of technology and passion for education, he worked at a local community college teaching aspiring laboratory technologists. In addition, Dave felt a great sense of comradery with his coworkers at John C. Lincoln, where he worked as laboratory supervisor serving the greater Phoenix community for the last 25 years. Dave was preceded in death by his mother, Josephine, and his father, Edward. He is survived by his children, Kristina, Kassie, and Adam; and his brother, Roy. He will be deeply missed by his friends, family and all who knew him. A graveside funeral service is scheduled for 1:00 pm on Wednesday January 20, 2021, at Paradise Memorial Cemetery and Crematory at 9300 E Shea Blvd, Scottsdale, AZ 85260. In lieu of flowers or gifts, the family would appreciate a donation to St. Jude: His family also prepared the following slide show of their favorite memories:

Dave Fronczyk was a kind and gentle person in every regard. Although Dave was reserved, he had a dry sense of humor. He was well liked and respected not only by his coworkers, but also nurses who came to pick up blood, physicians and drivers from Vitalant (formerly Blood services). Dave was the fourth and longest serving blood bank supervisor at John C. Lincoln Medical Center and took our blood bank to new levels of innovation and technological advancement. With his SBB (Specialist in Blood Bank) certification and advanced expertise in blood bank technology, his forward thinking was clearly cutting edge in transfusion medicine. Some examples include development of our massive transfusion protocol, emergency blood issue, collaboration with ED doctors and trauma surgeons to transport blood to remote areas of Arizona, first ProView analyzer in Arizona for ABO/Rh and antibody ID, implementation of Meditech and Haemonetics computers for Blood bank and Dave was instrumental in setting up intraoperative PTH testing in our laboratory. I can’t tell you how many times Dave and our blood bank team under his leadership were complimented for their timeliness and thoroughness by the trauma surgeons and anesthesiologist. He was involved directly or indirectly in saving people’s lives on a regular basis. Most of all, he loved his kids so much and was so proud of their educational and career accomplishments. Any time I asked how are you kids doing, his eyes would light up and he would go on and on about Kristina, Kassie and Adam.

Dear Fronczyk Family,

I was a co-worker of Dave’s for ten years. I was the shift to follow his shift in Blood Bank and when I would walk in he would say, “ Oh no, here comes trouble”. He ended up giving me the name the Blood Bank “jinx”as what could happen, of course, did happen. I loved his sense of humor. He made me laugh everyday! I am saddened by his death and he will truly be missed. My thoughts and prayers go to the family during this difficult time.

I worked with Dave from 2010 to 2014. He was always so calm in BB and very smart. He taught me a lot about transfusion medicine. We would often chat about his children. He was so proud of all 3 of you. May he rest in peace.

Dave was such a sweet man. I worked with him at JCL for 20 yrs and always peeked into Blood Bank each morning to say Hi to him. I always joked with him that I was glad he was there so that I didn’t have to work in that scary department. He was always so caring as I went through trials and tribulations in my life, always wanting to know how I was doing which meant so much. I would often times sneak my homemade cookies into BB for him as I knew he liked them so much! I was shocked and saddened by his passing. I will miss him dearly. Xoxo Dave, Rest In Peace.
