About the practice

About the practice.

N1 Plastic Surgery was founded by Professor Marcos Sforza, one of the most influential figures in modern breast surgery. A global thought leader, published researcher, and educator whose preservation techniques are now performed by surgeons around the world, Sforza has spent his career pushing what breast surgery can achieve. Dr. Foued Hamza brings over 25 years of consultant-level experience, with particular depth in body contouring and fat transfer. Professor Ash Mosahebi was among the first in the UK to perform VASER liposuction and holds senior teaching positions at the Royal College of Surgeons.

The practice covers breast surgery, body contouring, and facial treatments. Patients arrive having researched carefully and leave with results that are specific, natural, and proportionate to them. Sitting across from this team in a consultation means sitting across from surgeons who have spent careers setting the standard others are still working toward.
