Board of directors
Ernest Spitzer, MD
Chief Medical Officer
Dr. Ernest Spitzer is a cardiologist trained in Zaragoza, Spain, with focus on cardiovascular research. Before joining Cardialysis in 2014, he completed advanced training in cardiovascular imaging in Vienna, Austria, and a research fellowship in interventional cardiology in Bern, Switzerland. Dr. Spitzer is the Chief Medical Officer at Cardialysis, ensuring medical and clinical trial expertise in processes such as endpoint adjudication, data and safety monitoring boards, medical monitoring, safety reporting, trial design, and core lab processes, in close collaboration with operational and scientific experts.
Dr. Spitzer graduated summa cum laude in 2015 from the Catholic University of Saint Mary, Arequipa, Peru, and served two years at the Peruvian Armed Forces. He completed his cardiology training at the University Hospital Miguel Servet, Zaragoza, Spain. He was awarded a research fellowship from the European Association of Percutaneous Cardiovascular Interventions of the European Society of Cardiology and a research fellowship from the Spanish Society of Cardiology. In 2014, he completed a 4-year master program in statistics and research methodology at the Autonomous University of Barcelona. He has contributed with 60+ articles in peer-reviewed journals and is Board Member of the Academic Research Consortium since March 2019.
Chief Executive Officer
During his almost 30 years tenure at Cardialysis, Mr. Frits Kesselring has taken many responsibilities that enabled the transformation from a locally oriented Core Lab spun off from the Erasmus Medical Center into the professional and global company it is today. Perhaps most impactful was his key role in setting up the current corporate Group structure, including ECRI, and roll-out of the first major ECRI project, GLOBAL LEADERS. At some point, when the facilities needed fundamental restructuring in order to enhance visibility and connect all co-workers thus far spread over two floors, Frits took project leadership turning a large empty concrete 2600-sqm 6th floor at the Westblaak Rotterdam into a state-of-the-art facility integrating fit-for-purpose the intimacy of personal spaces with interactive open offices with maximum daylight.
Born in Rotterdam, his no-nonsense, loyal and dedicated attitude just makes things happen. As an explicit supporter of ‘his’ soccer team Sparta, Mr. Kesselring is collaborative and goal-oriented and over the years, he moved from the precise junior accountant of middle-sized companies like Cardialysis, when he just joined from PriceWaterhouseCoopers, into a more visionary financial leader and is the Chief Executive Officer at Cardialysis. He is critical, analytic, yet still helpful and no-nonsense; trusted and reliable when it comes to achieving a fair deal in his current position.
