Mac was only four months old when his parents were told he had cancer. What started as mild congestion and a distended belly after a routine ear infection led to an ultrasound—and the discovery that his kidneys were unusually large. Further testing revealed that 75% of his blood was cancerous. He was diagnosed with infant B-cell ALL, a high-risk form of leukemia.
Within 24 hours, Mac had surgery to place a central line and began treatment at Johns Hopkins. His care team moved fast—and so did the cancer. During his first 10 days of treatment, Mac lost nearly two pounds of cancer cells.
Over the following year, Mac spent nearly 200 days inpatient, enduring multiple rounds of chemotherapy and a month-long immunotherapy that required him to be continuously connected to a treatment pump. Through it all, his family adapted, strapping his pump to a scooter so he could learn to crawl.
In January 2024, Mac began maintenance therapy—a less intense phase focused on oral chemotherapy. If all goes well, he’ll ring the bell in February 2026.
Despite it all, Mac is full of life. He loves bacon, hot dogs, Buzz Lightyear, and going fast on the swing with his dad. His big sister, Marlo—“Mother Marlo” at daycare—has been by his side every step of the way.
Mac’s family has remained strong, supported by loved ones, an incredible medical team, and their faith. “You just feel so helpless,” his mom said. “But you have to keep going. In the cancer world, it’s second by second. And somehow—we keep moving.”
Through Just In Power Kids, Mac’s family received support that made a real difference: hospital parking passes, a welcome Power Pack (including a blender they still use daily), and Clean Cuisine meals that brought relief after long days.
Mac is being honored on Day 4 of the Maryland Trek, and his family proudly wears shirts that say “Macky Moo – Move Over, Cancer.” He is a true fighter—one who has faced the unimaginable and continues to smile through it all.
“He doesn’t know any different,” his mom said. “His whole life has been this—but he’s handled it with so much strength. Being a Power Kid is an honor to that fight.”
