Welcome to the Weight Loss Surgery Institute (WLSI) home page. We are proud to offer the only comprehensive weight loss surgery program on the California Central Coast. We offer the cutting edge in surgical technology and modern equipment, conceived specifically to accommodate complex and morbidly obese patients.

Our program, led by Minimally Invasive and Bariatric surgeons Dr. David Maccabee and Dr. Edward Felix, integrates medically supervised weight loss, a dedicated full time Bariatric Nurse Coordinator, dietician, pharmacy, rehabilitation/wellness center, and medical specialists from every specialty to provide complete care for every patient.

Drs. Maccabee and Felix and the staff of the Weight Loss Surgery Institute believe strongly that patient/ family education and involvement is crucial for patient success and optimal weight loss.

We believe that surgery is an effective tool to achieve meaningful weight loss for patients addressing weight loss issues, but that it is only a tool which must be used correctly by well educated and informed patients. Intensive dietary and nutritional counseling, both pre and postoperatively, long term follow up, physical and emotional support are all important and necessary components which contribute to success.

We fully assess every organ system of every patient preoperatively and spend time considering the ramifications of surgery in each case.

We believe that our comprehensive approach to offering surgical weight loss creates the greatest chance for success. We hope you will join us on a journey to better health.
