Our History

Our history

Since its inception, Sisu Clinic has strived to create a personalised approach to patient care and unparalleled service centered on establishing a dynamic partnership between patients and their practitioners. Founded in 2018 by medical co-founders Dr. James Cotter and Dr. Brian Cotter and serial tech entrepreneur, Pat Phelan, Sisu has focused on safely bringing advancements in aesthetic medicine to the masses, offering a comprehensive range of innovative cosmetic treatments including botox, dermal fillers, skin boosters, and more.

“The Botox Brothers” Beginnings

“The Botox Brothers” beginnings

Upon graduating from medical school, Dr. James Cotter and Dr. Brian Cotter found themselves balancing their work as general surgeons and internists in Irish hospitals by day while treating a growing number of patients for cosmetic procedures at off-site clinics part-time. During this period, the brothers were appalled to observe that many area clinicians were putting profits before patients by offering treatments from unqualified providers with little to no training. Called by their medical oath to “first, do no harm,” the brothers felt compelled to evoke a change in the industry, establishing a practice to put medical expertise and patients at the forefront of cosmetic and aesthetic care.

"As a clinician, I am aware of the profound effect our outward appearance can have on our internal psychology and how we interact with other people. At Sisu, when our patients leave they feel more confident and therefore interact with the world in a more positive way."

Dr. Sarah Conway

"As a results driven individual, I pride myself on achieving the best possible result for each patient I treat. Every day and each patient is different and this adds to the fun and the challenge of the my work."

Dr. Oisin Browne

"My favourite part of working with patients is seeing their reaction when they achieve the natural results they are looking for."

Dr. James Cotter

"Sisu's ethos–as well as my personal view on aesthetic medicine– is to focus not just on a singular treatment but the patient as a whole. It is the connection of the patients needs and wants with the best possible treatment to ensure best results and full satisfaction."

Dr. Brian Cotter
