Dr Wreesmann completed medical school and general otorhinolaryngology (ENT) training in Amsterdam, The Netherlands. Next, he was licensed as a physician in the United States, where he trained and worked for 6 years as a cancer surgeon and scientist at the Memorial Sloan-Kettering Cancer Center in New York. He then moved to the United Kingdom, where he worked for 7 years as a Consultant ENT-Head and Neck Surgeon within the National Health Service (NHS). In March 2022, he relocated with his family to Andorra where he sees patients at Clínica Omega Zeta. He continues his work in the UK, where he holds a position as honorary consultant ENT surgeon at Oxford University Hospitals. Dr Wreesmann is a driven academic and author of many scientific papers and surgical textbook chapters, published in the international medical literature (available on PUBMED and Google). He currently serves on the editorial board of the European Journal of Surgical Oncology, the official communication of ESSO, Europe’s largest association of cancer surgeons. As part of this work, he is a regular reviewer of scientific manuscripts, academic theses, and international research projects and has been a course director of several international medical conferences.
Dr Wreesmann favours a holistic and integrative approach to medicine, and offers a multidisciplinary solution wherever this is in the best interest of his patients. In order to achieve this, he works in close collaboration with nutritionists, dieticians, speech and language therapists, physiotherapists, endocrinologists, dermatologists, dentists, maxillofacial surgeons, neurologists, respiratory physicians, infectious disease specialists and family practitioners, some of whom are available at Clínica Omega Zeta. Dr Wreesmann values a straightforward, open, honest, empathic, and non-judgmental interaction with his patients. He aims to empower his patients, in order to optimize their independence, self-determination and autonomy. Within this context, he provides a balanced assessment of all risks and benefits of diagnostic and treatment options in order to be able to compare them accurately. This process is not only guided by the strengths but also the limitations of available scientific and practical knowledge, in order to create a solution which is tailored to the individual situation.
At Clínica Omega Zeta, Dr Wreesmann is happy to see both adults and children and aims to offer patients a same day diagnosis and treatment plan wherever possible. This is facilitated by the use of state-of-the art equipment to aid resolution of your problem. This may include in-office endoscopy of the nose, throat and oesophagus/stomach, and several other procedures which can be performed under local anaesthesia in the clinic. For patients with more complicated problems, or patients that require surgery, Dr Wreesmann has established (surgical) privileges at Centre Mèdic i Quirúrgic (Andorra), Hospital Nostra Senyora de Meritxell (Andorra), IMO Grupo Miranza (Barcelona), and Hospital Universitari Dexeus (Barcelona), where he may either refer you for more indebt diagnostics, or perform your surgery. Dr Wreesmann is a big proponent of second opinions in medicine and surgery, and will not hesitate to offer you one, in case your medical problem is outside his area of expertise. Dr Wreesmann runs clinics 5 days a week, some of which are planned in the evenings. For international patients, or patients who are not in a position to come to the clinic, Dr Wreesmann is available for virtual counselling as well, which can be requested on an individual basis.
