Patient Testimonial
“It all began with an annual mammogram. That’s what started this journey. I’m so thankful for the high caliber of care I received. It was amazing and a positive experience. You had a voice in your care. You had someone who was your advocate and held your hand along the way. It’s a beautiful place. It was like having an extended family. If there is a way to make cancer a great experience, the Delbert Day Cancer Institute did it. They are world-class people—every one of them. It’s the best place in the world. We have a powerhouse of talent and care right here in our neighborhood. I can’t say enough good things.”
