Why Choose Crystal Springs Surgical Associates?

- Crystal Springs Surgical uses the latest/newest minimally invasive surgical techniques to treat morbid obesity.
- Dr. Feng uses the latest technique of the restrictive vertical gastrectomy, which may replace the gastric bypass in the long term. The vertical gastrectomy, also known as the sleeve gastrectomy, appears to allow for better results, outcomes and may be safer with fewer short-term and long-term complications.
- Dr. Feng is one of the most experienced surgeons with a compassionate, caring and comprehensive weightloss program with long-term follow up.
- Center of Excellence: After 4 years as Medical Director of Bariatric Surgery Services at California Pacific Medical Center, Dr. Feng is now the Medical Director of Bariatric Surgery Services at Sequoia Hospital. As Director, Dr. Feng helped CPMC become a Center of Excellence designated by the American Society for Metabolic and Bariatric Surgery. This designation means that while complications are possible in any surgery, the rates of complications performed at a Bariatric Surgery Center of Excellence are extremely low. Dr. Feng is excited about Sequoia Hospital becoming an ASMBS Center of Excellence. His involvement in this process has created a hospital program that has allowed patients to receive excellent care in a supportive, compassionate, experienced and comprehensive environment.
