David A. Ruben M.D., MBA

I am saddened by this news. Dr. Ruben was truly one of a kind. I was his patient for many years until I returned to Texas in 2015. He was thoughtful, caring, brilliant, and he had a sense of humor. Death is inevitable, but a life well lived, is the measure of a good human being. Dr. Ruben was exceptional. I am grateful to have known him. My deepest sympathy to Ari and all of Dr. Ruben's family. Respectfully, Karen Wilson

With deepest sympathy. David, family, and all who loved him are in my prayers.
