I want to extend my deepest gratitude for the care, compassion, and expertise shown to me by Dr. DeLange. After nearly 40 years of living with the relentless burden of migraines, I had almost lost hope of ever finding real relief. But thanks to him, that hope has been renewed-and more than that, I'm finally experiencing meaningful relief.His thoughtful approach and deep understanding have made a life-changing difference. For the first time in decades, I feel like I have a future not defined by pain. Thank you, Dr. DeLange, for giving me back a sense of peace and possibility. I will always be grateful.
