Mark McLaughlin visited the emergency room for an unusually sharp headache, where he was diagnosed with glioblastoma mutliforme – an aggressive, baseball-sized tumor in his brain. McLaughlin’s tumor was removed, and he received treatment from neuro-oncologist Dr. Morris D. Groves at the Austin Brain Tumor Center. McLaughlin, a former Wall Street bond trader, has maintained a strict fitness regime following his cancer diagnosis, and he impacts those around him by continuously inspiring hope with a positive attitude.
