Dr. Hazen sees patients within the Preventive Cardiology Clinic, specializing in preventive cardiovascular medicine care of patients including treatment of hyperlipidemia, hypertension, obesity and diabetes. He also sees patients within the Cardiovascular Rehabilitation program. His research interests include studies of mechanisms for the development of cardiovascular disease, with emphasis on understanding the role of the gut microbiome, inflammation and oxidant stress in the pathogenesis of atherosclerosis and other inflammatory diseases.
A renowned physician scientist, Dr. Hazen has made pioneering discoveries in new understandings of mechanisms contributing to cardiovascular and inflammatory disease research. He is credited with numerous seminal discoveries linking gut microbial pathways to cardiovascular disease pathogenesis, as well as enumerating the role of myeloperoxidase and other inflammatory and oxidative pathways in cardiovascular disease.

He has published over 475 peer-reviewed articles in top tier basic and clinical journals alike in the fields of atherosclerosis, lipoprotein metabolism, gut microbiome, inflammation, vascular biology, and other topics related to preventive cardiovascular medicine. His research in multiple areas has impacted clinical practice, and lays the foundation for FDA- and EU-cleared diagnostic tests for cardiovascular disease risk assessment in use worldwide. He is listed as inventor on over 100 patents, and his research has helped to spawn pharmaceutical development of cardiovascular disease drugs in clinical trials.

Dr Hazen always stays with us until he has answered all our questions and concerns. He has always had a complete understanding of my heart and whole body condition. He's been a very good captain for my condition and care I am given at the clinic since my wife and I started coming to the clinic. He is the best.

Dr. Hazen was way above my expectations! He was prepared and ready with a plan for me!! He did not spend our time together reading about my record, as most doctors do, who clearly had not looked at who is there until he walks into the room, usually very late for the scheduked appointment. Dr. Hazen knew my history. He explained the change in medical treatment currently ongoing as it related to me. I appreciated and loved the clear and detailed explanation, the data and research results he shared, and all the time he spent with me, not hurried or dismissive. His knowledge and mannerism and responses to my questions could not have been better! I feel I have a positive path forward to prevent another heart attack, thanks to him! I found him on my own! Why did no other Dr. I have seen sonce my heart attack send me to him or to the Cardiac Prevention arm of the Clinic???

Dr. Hazen was exceptional. I have already referred two other people to him. I really appreciated that he provided studies that I could review related to the treatment he prescribed and the amount of time he took to explain everything. His after visit notes are very easy to follow and review.
