Petro and Calvin Tulloch, in collaboration with leading medical and scientific experts on weight loss, founded the first SureSlim Wellness Clinic in 1996.

For years, Petro struggled against unhealthy obesity. "I cannot adequately express the indignity, humiliation, discrimination, and heartache I was made to endure because I was overweight," says Petro. "One of the most rewarding days of my life was the day my husband and I decided to research the cause of my obesity. Through our research and the subsequent 'birth' of the SureSlim programme, I was able to lose 88 pounds (and for the first time in my life maintain my weight loss). Now I am able to help others gain control of their weight and their lives."

Petro's own dramatic weight loss and maintenance was the first SureSlim success story. Since 1996, more than 150,000 people around the world have achieved and maintained weight-loss success with the SureSlim programme.

Not content to rest on their laurels, the SureSlim team continues to improve and refine the programme as new weight-loss research and techniques are tested and incorporated.

There are now over 120 franchised clinics worldwide in Australia, New Zealand, Canada, Germany, UK, South Africa, Zimbabwe, and Namibia.
