While practicing primary care, Drs. Craig Primack and Robert Ziltzer found that many of their patients struggled with high blood pressure, high cholesterol, diabetes, and joint pain. They grew frustrated, giving them band-aids for their problems and hoping for the best. They knew there had to be a more productive and transformative way to treat these serious health issues patients were facing when it occurred to them that many of these chronic conditions centered on a single culprit – excess weight! Unfortunately, at the time, there was not much that a primary care doctor had in their toolbox to treat obesity other than recommending they eat less and move more.

Dr. Ziltzer and Primack were searching for a better way to care for their patients. They pursued knowledge and specialty training in medical weight loss and became Diplomates of the American Board of Obesity Medicine. The knowledge and specialty training gave them the knowledge to create a comprehensive, evidence-based medical program designed to promote safe and effective weight loss.

This concept was introduced to their patients in their primary care practice, and soon, not only did their patients lose weight successfully, their chronic health conditions reversed. They also found that the patient’s need for medications for conditions like high blood pressure and diabetes declined, and their free-time activity levels and quality of life significantly improved.

They were seeing the joy of success in their patients, Drs. Primack and Ziltzer made a choice to focus solely on providing medical weight loss and, in December 2006, established Scottsdale Weight Loss Center (SWLC). They proudly have brought on several excellent clinicians to expand their vision. Since joining SWLC, Dr. John de Guzman, MD, Diana Bone, FNP-C, Kimberly Roberts, DNP, FNP-C, and Jillian Swope, DNP, FNP-C, have helped thousands of happy patients and have grown to the medical practice to 4 locations throughout the valley.

Their shared mission: Changing the weight of the world!
