About Denisa Hagau, MD

“I chose the field of cardiology because it is constantly evolving, challenging as well as extremely rewarding. I have always found it exciting to be able to care for the sickest patients and guide them back to health. What I find the most gratifying, however, is building a relationship with my patients over time; helping them understand their disease process and make the major lifestyle changes that truly lead to longer, healthier lives. I have found this is only achieved by listening closely to patient’s needs and concerns while working together as a team. It is truly an honor and privilege when patients put their trust in you to care for them. I strive to be the best doctor that I can be and take care of everyone as if they are my own family member.

“I have a strong foundation in general cardiology including the management of coronary artery disease, atrial fibrillation, valvular heart disease, cardiac disease in women and cardiovascular risk reduction. My specific focus is noninvasive imaging, including echocardiography, nuclear cardiology and cardiac CT.

“When I am not working, I find myself spending most of my time with my wonderful husband and our two beautiful children.”
