Our Beginning

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, to put medical expertise and patients first.
