Dr. Berk expertly guided me through the diagnosis, treatment, and surgical decision for constrictive pericarditis, a rare disease affecting the pericardium. My condition worsened with complications; I was failing fast. Dr. Berk sent me for an opinion from another renowned cardiologist at the Cleveland Clinic in Ohio. Everyone agreed and the surgery that followed was successful. There are many for whom I am thankful, but Dr. berk is the maestro who saved my life. Also, he is a fun guy.
