June is National Cancer Survivor's Month!

Overcoming the Obstacles:
You may recognize the Holtz Family name from their years of involvement in off-road racing. John Holtz, driver of the Yellow #477 Formula 4x4 Jeep, originally got his start in the infamous "Good Ole Boys" (G.O.B.) class at Crandon International Off-road Raceway in 1987. It wasn't long until he and his friends (Kendal and Warren) joined the Formula 4x4 class in 1992- where TFA Racing was born.
No stranger to the dirt, John has raced both short-course and competed in numerous desert races. John began competing in the Baja 1000 starting in 2002 - as well as the IODA Series, Dark Water 100 in Pennsylvania, Wild West 100 in Montana, the Baja 500, San Felipe 250, SCORE 250, and Mint 400 where he has pitted for both Curt and Todd Leduc.
In early January 2015, the doctor treating John told him that he was suffering from stage four, Mantle cell lymphoma, a deadly (and one of the rarest) forms of non-Hodgkin's lymphomas. John's 51 years of life suddenly took a devastating turn from the hopeful future he and his family looked forward to.

As is his custom whenever life throws him a challenge, John stood tall, marshaled his inner strength and faced the unknown head on. With the support of his family and friends, John underwent multiple rounds of intense chemo, a life-saving stem-cell transplant, and years of maintenance chemo.
In 2020, John's doctor shared, he was his FIRST patient to survive 5 years after that intense regimen of chemo.
“Appreciate everyday. I never have a bad day. Cherish the memories. Never give up hope...Drive hard and NEVER lift."
The Journey
John shares, " I decided to continue racing during my cancer diagnosis because my doctor pushed back my transplant date by a week and I was not given much chance of survival. Unfortunately the doctor found out (Nate-Dawg's wife, Jen, tutored his kids), and he said 'absolutely not'.
Luckily, my good friend Dennis Chencharick from Pennsylvania stepped in to race my Jeep for me while I watched from my hospital bed at Froedtert. He made the podium and finished third on day one, but on day 2, my transfer case exploded." Dennis Chencharick is also a former off-road racer - he raced in classes 3, 8, and 13 from 1970s - early 2000s. Since October 2015, John has been in remission. However, he has continuously undergone maintenance chemo and regular scans to ensure it's caught and treated in time if or when it returns.
