Two disciplines, one standard.

Dr Alan Farrell

Alan founded Quantum to bring preventive, doctor-led men's health to men across Ireland. A medical doctor whose career spans elite professional-sport medicine and preventive medicine, his focus now is the wider picture: where men's health is heading, and the responsible use of AI in healthcare, on which he is a recognised voice.

He leads Quantum as a business; the consultations and clinical care are delivered by its medical team. The aim Alan built Quantum around is unchanged: give each man an accurate picture of his health, and a clear plan to act on it.

Brian Cashman

Brian leads the performance side of Quantum. He holds an MSc from UCD with postgraduate study in psychology and high performance, and his approach is built on the Hintsa performance model used at the elite end of sport.

With a C-suite background in high-growth business, he has worked with organisations including Spotify, McLaren Racing, KPMG and AIB, and delivers large-scale culture and leadership programmes alongside Archipelo Coaching and change expert Damian Hughes. At Quantum he turns better health into sustained performance — for individuals, teams and the cultures they work in.

Dr Ahmed Saleem

Dr Ahmed Saleem is a vocationally trained GP with a special interest in men's health and hormone optimisation, combining the breadth of general practice with focused expertise in testosterone, metabolic and preventive men's health care. He leads clinical care at Quantum, guiding you through your results and your plan.
