He has served as an Associate Professor of Cardiology at both the University of South Florida and Nova Southeastern University, where he combines practical clinical experience with academic instruction. His ability to bridge research and real-world practice has made him a respected educator among medical students, residents, fellows, and practicing physicians alike.
Board certified in Internal Medicine, Cardiovascular Disease, and Interventional Cardiology, Dr. Krolick has developed particular expertise in coronary artery disease, peripheral arterial disease, venous disorders, structural vascular disease, and complex endovascular interventions. His clinical interests include minimally invasive procedures for peripheral vascular disease, treatment of abdominal aortic aneurysms, critical limb ischemia, deep vein thrombosis, and advanced catheter-based therapies that offer patients effective alternatives to traditional surgery.
Dr. Krolick has consistently remained at the forefront of cardiovascular innovation through his participation in numerous national clinical research trials. As a principal investigator, he has helped evaluate emerging cardiovascular medications, coronary drug-eluting stents, drug-coated balloon technologies, peripheral vascular devices, and other breakthrough therapies that have contributed to significant improvements in patient care. His research efforts have helped introduce new treatment options while expanding the evidence base that guides modern cardiovascular practice.
An accomplished author and lecturer, Dr. Krolick has published scientific research in respected peer-reviewed medical journals, including The New England Journal of Medicine, and has contributed chapters to leading cardiovascular textbooks. His expertise has also made him a sought-after national speaker, presenting educational programs on interventional cardiology, peripheral vascular disease, hypertension management, and advances in endovascular therapies. Through these educational efforts, he continues to share knowledge that benefits physicians and patients well beyond his own clinical practice.
Dr. Krolick's professional leadership extends into numerous medical organizations and community initiatives. He previously served as Chairperson and Director of the Pinellas County Chapter of the American Heart Association, supporting programs that promote cardiovascular health education, disease prevention, and public awareness. His dedication to community outreach reflects a belief that preventing heart disease through education is every bit as important as treating it through clinical intervention.
Patients and colleagues alike recognize Dr. Krolick for combining exceptional technical skill with compassion, integrity, and individualized care. He believes that successful treatment begins with listening carefully to each patient's concerns, educating them about their condition, and developing personalized treatment plans that support both longevity and quality of life.
