The Callahan Murphy Hare Fdn

Rare diseases are defined as affecting less than 200,000 people.

Some forms of childhood cancer are more common than others, but each of the individual types of childhood cancer is recognized as rare under this definition.

For our family, our rare disease is an ultra rare form of childhood cancer.

Infant leukemia affects approximately 90 babies (12mo or younger) every year. Almost every case comes with an unfortunate gene mutation, KMT2A. This mutation, commonly referred to as MLL-rearranged, makes the cancers it affects very aggressive, hard to treat and delivering poor prognoses.

It’s often hard to reconcile how Callahan beat the odds, especially combined with being diagnosed so incredibly young at 19 hours old.

This experience and reality drives our resolve to advocate not just for his rare disease, but for all childhood cancers.

On this Rare Disease Day, we are grateful to share our rare disease and to have the opportunity to impact research that works to improve not only survival rates, but long-term impacts of outdated, toxic solutions.

2026 Blood Drive kickoff take ✌️!

Rescheduled due to winter storm Fern, we’re back on for this Sunday, Feb 1.

Every TWO SECONDS someone in the U.S. needs blood or platelets. 🅰️🅱️🆎🅾️

The need is critical and the supply and demand barely keep up with just 3% of the eligible population donating — and this is down from 5%.

Want to make a real and immediate difference? Donate blood.

➡️ All first time donors will be entered into a raffle for a $250 Amazon gift card (delivered YE 2026).

Appointments typically take 30 minutes door-to-door — less if you do your check-in questionnaire before arrival ;)

All donations through Versiti help local patients within days 🙌❤️‍🩹

Join us to support and increase our regional blood supply!

Our community art project from Kids in Capes is officially complete!

A true labor of love that required many phases beyond the event to finalize throughout the fall and holidays.

We are thrilled to share “Lighting the Way,” an illustration of hope and momentum, moving from dark to light as more voices get loud about childhood cancer, creating more awareness and opportunities for funding newer, kinder treatments for kids with cancer.

We cannot wait to see this piece grace the walls of H11 at Nationwide Children’s for all the clinic kids to see and understand the advocacy that is happening on their behalf.

Thank you to everyone who helped bring this piece together. It is an incredible symbol of community and the great things we can do together.

We’re excited for what’s next and already brainstorming our next community art project for KIC year 5!

🔗SCHEDULE YOUR APPT IN BIO 🅰️🅱️🆎🅾️

AND, we are reinstating our same challenge from last year — ✨all first time donors will be entered into a drawing to win a $250 Amazon gift card ✨ The winner will be pulled after the November drive.

Congrats to our 2025 winner, Matt Boorman!

Matt donated for the first time last year at one of our drives to honor his sweet daughter, Laina. Laina tragically passed away in 2023 at 17 months old following her short battle with ETMR, an aggressive pediatric brain cancer.

Every single donation is meaningful for the donor and recipient. Who will inspire you to donate blood this year?

It seems small, but it clearly adds up. 𝐌𝐚𝐲𝐛𝐞 𝐰𝐞 𝐝𝐨 𝐭𝐡𝐞 𝐬𝐚𝐦𝐞 𝐭𝐡𝐢𝐬 𝐆𝐢𝐯𝐢𝐧𝐠 𝐓𝐮𝐞𝐬𝐝𝐚𝐲?

𝐖𝐨𝐮𝐥𝐝 𝐲𝐨𝐮 𝐩𝐥𝐞𝐚𝐬𝐞 𝐜𝐨𝐧𝐬𝐢𝐝𝐞𝐫 𝐝𝐨𝐧𝐚𝐭𝐢𝐧𝐠 𝐭𝐡𝐞 𝐜𝐨𝐬𝐭 𝐨𝐟 𝐲𝐨𝐮𝐫 𝐝𝐚𝐢𝐥𝐲 𝐜𝐨𝐟𝐟𝐞𝐞 𝐨𝐫𝐝𝐞𝐫 to help fund our 2025 research grants for pediatric cancer research?

It’s sobering comparison that really puts the deficit of funding for kids with cancer into perspective.

CMHF focuses on supporting immunotherapy research and work that impacts our most vulnerable childhood cancer population: babies.

Projects are both at the bench level (CMHF kickstarted the work for MLL-rearranged (KMT2A) infant leukemia (Callahan’s disease) at CHOP) to later stage patient trials.

➡️ See our Impact page for more info, linked in bio.

Thank you for helping us fill the funding gap to move the research needle forward so one day children no longer have to pay the price of this unbelievable underfunding.

Here’s the math:

17,286 U.S. stores x $3,288 ave. daily sales = $56,836,368

$56,836,368 x 5 days = $284,181,840 ✏️(edit: graphic should say “five days” not three. However, three days is nearly the annual budget anyway at +$170M)

May we always look for the silver linings even in the most challenging circumstances.

Eternally grateful for every piece of this journey that gave us so much perspective and purpose, and most of all, to every one who has joined us in the cause. ♥️

Happy Thanksgiving!

Humbled is an understatement. 💛

Our sincerest gratitude to Burbank Early Childhood School for their 2nd annual Coins for Cancer drive benefiting our childhood cancer research grants.

This week, our youngest Golden Bears celebrated the amazing success of their Coins for Cancer fundraiser! 💛🐻

Our preK students at Burbank Early Childhood School saved pennies, nickels, dimes and quarters to support childhood cancer research — raising an incredible $3,100. Thanks to a generous anonymous donor, that total was matched for even greater impact!

We’re so proud of our students for going GOLD and supporting one of their own during Childhood Cancer Awareness Month. 🌟
