About me

Dr. Catherine Dao is a cardiologist who cares for patients with a variety of cardiovascular conditions, including arrhythmia (irregular heartbeat), cardiomyopathy (diseases of the heart muscle), and coronary artery disease. She has particular interests in echocardiography (ultrasound imaging of the heart), preventive cardiology and women's heart health.

Dao earned her medical degree at the Icahn School of Medicine at Mount Sinai. She completed a residency in internal medicine at Cedars-Sinai Medical Center, followed by fellowships in cardiac MRI and cardiovascular medicine at Stanford Medicine.

In her free time, Dao enjoys cheering for the Golden State Warriors, hosting dinner parties and traveling abroad. She also loves to spend time outdoors; she climbed Half Dome in Yosemite National Park when she was three months pregnant.

      Dr. Dao is obviously intelligent because she is a doctor. However as far as compassion, caring humility, professionalism and her lack of awareness how she comes across, I would not recommend her to anyone and moving forward I will be looking for a John Muir Health Cardiology if/when I need follow up. I felt like I was being treated by an AI doctor. All my other past/present experiences have been great. Not Dr. Dao

      I had a very thorough visit with my care provider. She was generous with her time and expertise, and took care to make sure I had all questions answered and understood all that we discussed.

      Dr. Dao provided truly outstanding care. From the moment we began our visit, I felt heard and supported. She took the time to really listen to my concerns and walked me through everything in a way that was clear, thoughtful, and easy to understand. I especially appreciated how thoroughly she reviewed my lab work and explained her perspective, concerns, and recommendations without making me feel rushed.Our conversation felt collaborative and reassuring, and I left the appointment feeling much more at ease. Dr. Dao's care, patience, and attentiveness made a meaningful difference for me, and I'm very grateful for the time and effort she put into helping me understand my health.
