AirLein Medical is the aviation medical examination practice of Marjolein Deege.
As a third-generation pilot, aviation is in her blood. She is both a doctor and a pilot, combining her medical expertise with her love of flying. Her practice is based at Hilversum Airport, putting her right at the heart of the aviation community. She obtained her first pilot licence in 2004 and now flies SEP, MLA and TMG aircraft. With a practice right at the airport and an active role in aviation, she understands better than anyone what matters to pilots.
Marjolein studied Medicine at Utrecht University, then specialised as a medical microbiologist at UMC Utrecht and has extensive experience in healthcare. She also taught Human Performance and Limitations for many years as part of the PPL theory course. Sharing knowledge and guiding people are therefore important parts of her professional background. The combination of her medical expertise and passion for aviation ultimately led her to train as an Aeromedical Examiner (AME) and establish AirLein Medical.
Having completed both the basic and advanced Aeromedical Examiner training, she can conduct Class 2 and LAPL medical examinations, as well as renewals for Class 1 and 3. Her approach is centred on expertise, personal attention and practical advice. Marjolein understands the challenges pilots may face, from both a medical and operational perspective. She is happy to take the time to answer questions, explain things clearly and work with pilots to find solutions when medical conditions affect their ability to fly.
Alongside her work at AirLein Medical, Marjolein is actively involved in the further development of aviation medicine in the Netherlands. She is a board member of the Netherlands Society of Aviation and Space Medicine (NVvLG) and contributes in this role to knowledge sharing, professionalisation and quality improvement in the field.
Whether you need an initial medical examination or a renewal, AirLein Medical puts personal attention, expert advice and a positive experience at the heart of every appointment. Examinations are carried out by a doctor who knows aviation not only from the consulting room, but also from the cockpit.
David de Vries has been working at our practice since July 2026.
David de Vries is a pulmonologist with extensive experience in respiratory medicine. After studying Medicine at the University of Groningen, he completed his specialist training in London and Ghent. He subsequently worked in Curaçao, Boxmeer and Harderwijk, and from 2010 to 2025 at Merem Behandelcentra in Hilversum. Since 2019, he has also worked as an Aviation Medical Examiner (AME LAPL, Class 1 and Class 2), conducting medical examinations for pilots. What he particularly enjoys is the personal contact with pilots. He enjoys providing information and advice, and considers it important to support and guide pilots when a fit-to-fly decision needs to be deferred.
Aviation also plays an important role in his personal life. He earned his RPL licence in 2008 and his PPL licence in 2009, and has since logged around 1,100 flight hours on aircraft including the Piper PA-28 and Cessna 172. He enjoys flying with friends and passengers, and for Stichting Hoogvliegers, which gives children with an illness or disability the chance to enjoy a special flying experience. His favourite destinations are the Dutch and German Wadden Islands, and since 2025 he has coordinated introductory flights for prospective members at Vliegclub Flevo. Aviation remains an important hobby at home, too. Through the international VATSIM network, he regularly flies virtually in aircraft from the Airbus A320 family.
His experience as a pulmonologist, his involvement in aviation and his enjoyment of guiding and informing people make him a valuable addition to our team.
In October 2026, we welcome Rob de Winter to our practice.
Rob de Winter is a cardiologist and worked until 2025 as an interventional and congenital cardiologist at Amsterdam UMC. He studied Biophysics at Leiden University and Medicine at the University of Amsterdam. As a professor of clinical cardiology, he spent many years conducting research into the diagnosis and treatment of coronary artery disease and congenital heart conditions.
At Cardiologie Centra Nederland, Slotervaart location, Rob holds dedicated clinics for patients including pilots who need additional cardiology tests for their aviation medical examination. After completing the basic course in aviation medicine, he was certified as an Aeromedical Examiner (AME) at the end of July 2026. From autumn 2026, he will conduct Class 2 and LAPL aviation medical examinations at AirLein Medical.
Rob is involved in aviation not only from a medical perspective, but also as an experienced pilot. His interest in flying began when he flew along from Teuge on photographic flights to map the Dutch heathlands. In 1993, he obtained his PPL at Hilversum. In 2006, he expanded his flying experience with an instrument rating on the TB10 and TB20 at Lelystad. With more than 2,000 flight hours to date, mainly on the Piper Archer and also on the Piper Saratoga, Rob knows the practical side of flying well. His favourite destinations range from Texel to various destinations in Belgium and France, including Ostend, Le Touquet, Lognes-Emerainville, Aubenas and La Mole-Saint-Tropez. What appeals to Rob about aviation is not just flying itself, but also the community around it: a world of committed, knowledgeable and helpful people, with a practical outlook and a sense of adventure.
Thanks to his many years of experience in cardiology and his own flying experience, Rob can approach medical questions from both a specialist and a practical perspective. He wants to use his cardiovascular expertise to help pilots maintain their medical fitness and, where possible, continue pursuing their passion for flying for as long as possible.
