He is facile with ultrasound and stimuplex (electrical impulse) techniques. His focus has evolved from management of trauma patients to aiding patients with neurodegenerative diseases. After losing his father to a difficult battle with Multiple Sclerosis, he has made it his mission to alleviate pain and suffering and to improve the quality of life for those with progressive and advanced neurological disease.
“I believe that we live in a great time in history, where we can alter and scale back the progression of neurodegenerative illness. I am honored to be able to play a small role in giving back to you your independence and helping you live a more comfortable and enjoyable life. My wish for you, as a patient of Stemedix, is that you have better and more effective treatment options than my father did while he was struggling with his illness.”
