Ioannis Ntanos (pronounced Danos) is one of the UK’s leading gender affirmation surgeons, specialising in top surgery for trans men.


Born in Thessaloniki, Greece, Mr Ntanos obtained his medical degree from the University of Ovidius in Constanța, Romania in 2002. From there he returned to Greece to complete his general surgical training and to work as a consultant. In 2010 he completed his oncoplastic training, at the Gustave-Russy Institute, in Paris, France, qualifying him as a specialist breast surgeon. In 2013, he moved to the UK where he took up a surgical position within the NHS.


Mr Ntanos’ passion for ethics and how they relate to healthcare, led him to obtain a degree in Ethics and the Law from the University of Manchester in 2011. While at North Manchester General Hospital (NMGH) Mr Ntanos began specialising in top surgery for trans men and in 2019 he became the lead for gender affirmation surgery.


During his time working as a specialist in this area, Mr Ntanos has performed more than 820 cases of top surgery. In 2019 he was named doctor of the year at NMGH, and in 2020 he was appointed as chair of its clinical ethics committee, a role which he held until September 2022.

Specialising in top surgery for the trans and non-binary community has seen Mr Ntanos’ combine his dual passions of ethics and healthcare and he has since gone on to complete his MBA studies, with a thesis focusing on improving trans surgery and top surgery provision in the UK.


Mr Ntanos is continuously expanding his knowledge in this area and participates regularly in national and international conferences and workshops. He also provides training at all levels to those wishing to better understand this area of surgery and how best to support this patient cohort. Mr Ntanos is launching the first in a range of Masterclasses in Top Surgery in 2023 and has contributed the first ever chapter on top surgery to the 7th edition of Breast Surgery: A Companion to Specialist Surgical Practice, due for publication in October 2023.


Mr Ntanos has a number of professional affiliations including: membership of WPATH (World Professional Association for Transgender Health), BAGIS (British Association of Gender Identity Specialists), AoME (Academy of Medical Educators) IME (Institute of Medical Ethics) and CMI (Chartered Management Institute).


Outside of his passion for providing excellent care to transgender individuals, Mr Ntanos also enjoys reading poetry, playing the piano and travelling.
