DR. SAYEH ZIELKE

Meet Dr. Sayeh Zielke (a.k.a. Dr. Z)

​

Cardiologist | Author | Speaker | Big Heart, Bold Vision

​

Dr. Sayeh Zielke is a cardiologist with a mission: to help people live longer, healthier lives. Starting with the heart. Known affectionately by many as Dr. Z, she’s not just a leader in cardiac care; she’s also a speaker, educator, and advocate for resilience, empowerment, and personal growth.

​

Dr. Z is the founder and Medical Director of Chinook Cardiology, and was the first cardiologist to establish a practice in Southern Alberta. She currently serves as the Physician Lead for Cardiac Sciences in the AHS South Zone, Chair of the South Zone Cardiac Sciences Advisory Cabinet, and holds academic appointments at both the University of Calgary and University of Lethbridge.

​

She earned her MD and International MBA from the University of Ottawa (where she was class valedictorian), and went on to complete specialty training in Internal Medicine and Cardiology at the University of Calgary, followed by advanced imaging training at Oxford-affiliated hospitals in the UK. She also holds her ICD.D designation for board leadership.

​

But beyond the credentials, Dr. Z is known for her relatable, down-to-earth style. A first-generation immigrant, she brings grit, compassion, and perspective to every patient interaction. She’s fluent in three languages, stands proudly at 5’1.4”, and is living proof that big things come in small, determined packages.

​

When she’s not in the clinic, you might find her delivering moving keynotes that use real cardiac science as metaphor for life, performance, and perseverance. She’s the author of One Heart, Five Habits, a practical, evidence-based guide to lowering blood pressure, and is currently on a mission to raise $30 million for cardiac care in Southern Alberta.

​

Dr. Z believes that every heart tells a story, and she’s here to help you protect yours, live fully, and lead with strength from the inside out.
