Our surgeons’ experience, teamwork, and attention to detail have helped to ensure successful outcomes for our patients.

Currently, our two surgeons performing weight loss surgery are Dr. Brian Chin and Dr. Jason Moy. Both are expert laparoscopic surgeons with fellowship training in bariatric surgery and all aspects of advanced minimally invasive surgery. They both dedicate a significant portion of their practices to bariatric surgery to ensure they maintain the highest skill level in bariatrics and stay abreast of the latest developments in the field. At the same time, they maintain an interest and practice in the full range of minimally invasive surgery, to ensure their skills remain well-rounded and broad.

They are dedicated to a safe and successful outcome for you, by performing technically excellent operations, and by paying careful attention to your specific needs and care throughout the entire process. Our surgeons conduct a detailed, multi-disciplinary preoperative evaluation on all patients considering surgery. They will see you post operatively on a regular basis for the first year after surgery, and every year for life. We want to make sure you continue to do well for the long term, and we want to share in your success by seeing how well you are doing!


Our surgeons offer all of the standard operations currently being performed for weight loss, including laparoscopic roux-en-Y gastric bypass, laparoscopic vertical gastrectomy (sleeve gastrectomy), laparoscopic adjustable gastric band, and laparoscopic duodenal switch. In certain situations, our surgeons may recommend one of these operations as the best option for you, but in most cases, the patient is able to choose which operation to have after discussing the options with one of our surgeons. We also perform revisional bariatric surgery on a case-by-case basis.

My Weight-Loss Surgery Story

My name is Denise. I started my weight-loss journey in December of 2014 by visiting Dr. Chin. It was ten months of doctors’ appointments, weigh-ins, and medical tests. But I was focused and determined. Finally, my surgery date came. I was sleeved in October 2015, and it was the best decision I have ever made for myself. I was 57 years old at the time. I asked my surgeon, Dr. Chin, if I was too old for the surgery, and he said, “No one is too old to get healthy.” He was so very right. I was 310 pounds at my heaviest, pre-surgery. I was pre-diabetic, and had high blood pressure. My back, knees, and ankles hurt most of the time, and I was always short of breath. Those were just the medical conditions I had because of my weight. I was self-conscious and depressed. I was very unhappy. Surgery was a piece of cake (no pun intended). I was walking on the treadmill within two days. Soon, I was amazed at the transformation I was having, both in my weight loss and with my attitude towards food. As the weight loss kept happening, I was gaining my health back. I am no longer on blood pressure medicine, and I am no longer pre-diabetic. My knees, back, and ankles don’t hurt anymore because I am not carrying so much weight. I can walk and move around without being short of breath. My confidence has returned, and I am so much happier now that I am 100 pounds lighter. I swim a mile five days a week, and walk three to four miles every day, and I enjoy it. There are so many accomplishments that have come from losing weight like shopping in the regular size section, fitting in any chair, crossing my legs, not having to ask for an extension on the airplane, and the list goes on. The only regret I have is not having this surgery sooner. I would like to thank Dr. Chin and all of the staff involved in my life saving/changing surgery.

Excellent 4.8 out of 5 star rating

Great Doctors!

Dr. Jason Moy performed by bariatric surgery last month.  I did enormous study on the surgery including watching 90 hours of video on YouTube.  Concerned about the surgery Dr. Jason Moy had an excellent bedside manner.  He is an excellent listener and very patient.  His staff is impeccable.  His confidence shown in me and the procedure remedied my nerves.  After surgery I was expecting some of the maladies I learned about after bariatric surgery.  To my surprise and because of an excellent surgery, I had minimal pain off pain meds next day, no sore throat or other irritable symptoms. I knew I was fortunate.  Fortunate to have an excellent doctor and surgeon.  If you plan to change you life and go in a better direction and get bariatric surgery I would expect you would want the best surgeon and doctor available.  I suggest you call Dr. Jason Moy.  I am sure there are other great doctors but if you are looking for a sure thing then it is Dr. Jason Moy.

Life Changing Surgery

I underwent Gastric sleeve surgery with Dr. Chin not long ago. I had a wonderful experience. The process for this Bariatric weight-loss surgery was made very smooth by Dr. Chin's great staff and the preparation and advice from Dr. Chin. I would highly recommend Dr. Chin to anybody thinking about having a life changing weight-loss surgery, he's one of the best Bariatric Doctors/Surgeons in the East Bay.
