Know Dr. W
I am Dr. Mariusz Wysoczanski a.k.a Dr. W, a board-certified cardiologist with a subspecialty in heart failure. My journey into the medical field began in my youth, driven by a deep-seated desire to enhance the quality of life for individuals grappling with various ailments. My background as a personal trainer and amateur bodybuilder fostered a profound interest in exercise physiology, which naturally extended to a curiosity and passion for the cardiovascular system.
My formal medical education was completed at the prestigious Poznan University of Medical Science. Following this, I undertook an internship, residency, and fellowship at Beth Israel Medical Center, where I received comprehensive training in cardiology and specialized further in heart failure. The extensive training and experiences gained during this period equipped me with the knowledge and skills to excel in my field.
Throughout my career, I have had the pleasure of co-authoring several published studies and contributing a chapter to a book on echocardiography and heart failure. These academic pursuits reflect my commitment to advancing the field of cardiology and improving patient outcomes through research and education.
I am currently quintuple board certified, a testament to my dedication and expertise in diagnosing and treating a wide range of cardiovascular diseases. My multifaceted approach allows me to apply a broad spectrum of skills and techniques to provide the highest standard of care to my patients.
At the age of 45, I have been in practice since 2014, bringing over a decade of experience to my role. I am affiliated with Sharp Chula Vista Medical Center, where I continue to serve my patients with dedication and compassion. Fluent in both English and Polish, I am able to communicate effectively with a diverse patient population, ensuring that language is never a barrier to excellent care.
In my practice, I strive to combine my extensive medical knowledge with my background in exercise physiology to offer a holistic approach to heart health. By understanding the intricate relationship between physical fitness and cardiovascular wellness, I aim to help my patients achieve optimal health and well-being.
Thank you for considering me as your cardiologist. I am committed to providing you with the highest level of care and support on your journey to heart health.
