About Marcel M Letourneau

About the Provider

As an interventional cardiologist, I often use minimally invasive, catheter-based procedures, like stenting and angioplasty, to treat patients with severe, complex conditions that need care urgently. Whether it’s a heart attack, massive lung clot (pulmonary embolism), or a critical blockage, it is my job to restore each patient’s health and guide them through recovery.

I enjoy coming up with a treatment strategy and plan that’s customized for each patient. Some patients wish to be more aggressive with their care and some more conservative. I focus on using my expertise and knowledge to recommend, support, and guide each patient through their decisions and care.

When I help improve someone’s health and see how much they have progressed, it’s fulfilling and gives me great professional satisfaction. Sometimes patients ask, "How can I thank you?" I love to respond by saying, live your life the best you can, enjoy every day, and commit to the restored health we achieved together.

    I hope to have a periodic check-in with Dr. Letourneau, not just an annual appointment. I would like to use the portal or email to optimize his time and mine. Hopefully this is a good approach.
