"I believe in individualizing care, which comes from good communication. That’s why I spend the time with my patients so I can thoroughly understand their needs and goals. This allows me to provide education about disease process and encourage them to actively participate in their health care so they can achieve their goals."
Dr. Kassis is married and has one child. He enjoys spending time with his family, teaching and reading.
