Patient Review of Dr. Marc Gillinov

"I can't thank Dr. Gillinov and the Cleveland Clinic enough."

-- Robin Williams, heart valve surgery patient

"Wonderful. Simply cannot praise Dr. Gillinov enough. Dr. Gillinov performed my first aortic valve replacement in August of 2010.

As things go, 15 years passed and I needed to replace the replacement. I turned to Dr. Gillinov again. Wonderful! Thank you Dr. Gillinov!"
