My Biography

Elias S. Kakish, M.D. – Pulmonary & Critical Care

I’ve had a passion to help people since I was a child – and I love the satisfaction that comes with diagnosing and treating the variety of lung and sleep disorders that detract from so many people’s quality of life. It’s important to me to invest time in explaining things to each patient. When I review lung images with someone, or show them the results of their sleep study, they can see what the problem is with their own eyes. This builds their confidence and trust in me as we work together on a treatment plan.

My Biography

Dr. Thai specializes in complex interventional cases such as patients with impaired heart function and those suffering from cardiogenic shock. He also performs high risk cardiac interventions such as reopening chronic total occlusion (CTO), left main interventions and in those patients who have been turned down for bypass surgery due to increased risks. He is interested in many new technologies emerging for cardiac care that allow physicians to better care for their patients.
