Dr Oliver Florica, MD FRACS

I am an Australian Surgeon at the Sydney Adventist Hospital, where I have been practicing for the last fifteen years.

I trained as a trauma surgeon in Cape Town and Johannesburg, South Africa and pursued another decade of advanced training in Australia. Through this I became proficient in various surgical specialties, such as laparoscopic and robotic surgery in bariatrics, as well as complex lower and upper gastrointestinal procedures, such as bowel cancer, diverticular disease, anti-reflux, hernia, and gallbladder. My expertise has been enhanced by additional years of training in surgical and orthopaedic trauma, plastic and reconstructive surgery, intensive care and advanced life support and resuscitation techniques in centres of excellence in South Africa and Australia. Over a period of more than ten years of training with six monthly rotations I have been awarded with assessments of excellence in my performance.

In 2002, I became a Fellow of the Australian College of Surgeons and subsequently a Member of the Australian Obesity Surgery Society. My training, however, has never stopped and I continue to stay abreast of most modern surgical techniques. In 2008 and 2012, I was awarded a Diploma in Laparoscopic Surgery from the University of Strasbourg, France. Prof Emeritus Paul O’Brien at the Alfred Hospital was my mentor and inspiration in my early years in bariatric surgery.

Throughout my career I have participated in or performed in excess of 20,000 surgical procedures and I am capable of surgery with excellent outcomes, satisfying high expectations.

Currently my practice is focused on laparoscopic and robotic abdominal surgery, bariatric procedures and cosmetic body contouring after weight loss. I am one of the first general surgeons in Australia to use the Da Vinci Robot in my field. I have performed multiple robotic bariatric and general surgery procedures and I have been asked to proctor in robotic surgery

In my private life, I am family man with four children from kindy to high school and a passionate aviator with over 1,500 hours of pilot in command in Australia and the USA where I own and operate several aircrafts. I am the only pilot to have flown a C172 across the Pacific Ocean from Michigan, US to Sydney, Australia and land the smallest aircraft at Kingsford Smith International Airport after an epic flight.
