Meet Dr. Brown: Pioneering a New Era in Bariatric Care

After opening the very successful Idaho BMI in 2019, Dr. Brown founded Everest Surgical Institute in 2021. The reason is simple. He wanted to take care of his patients in a new and better way, without letting daily politics or money get in the way.

His background is just as impressive. Dr. Brown studied medicine at University of California, Davis and completed his surgical residency at Dartmouth, where he earned awards for his leadership, scholarship, and respect for human life. He is also a fellow of the American Society of Metabolic and Bariatric Surgery (ASMBS).

Awards and experience aside, Dr. Brown is rooted in deep values from growing up on a 2,000 acre alfalfa farm with his parents and seven brothers and sisters. In fact, he still sees himself as a bit of a cowboy, blazing new trails in weight loss management.

His areas of expertise are bariatric surgery, revision bariatric surgery, nutrition and metabolism, ketogenic lifestyle, longevity, exercise science, and chronic metabolic disease.

Don’t live in Idaho? No problem. He’ll put you up in a local hotel and stay connected after surgery with telemedicine appointments.

Kate Armstrong

Nurse Practitioner

Kate has worked with Dr. Brown in the operating room since 2016 and shares his philosophy on bariatric surgery as a tool for overall success.

She feels privileged to hear patients’ stories and watch as they go from struggling to succeeding. In fact, the most rewarding part of her job is after surgery, seeing patients’ new sense of control in their relationship with eating.

She values hard work and creative problem solving, which she traces back to growing up on the family cattle ranch.

When she’s not on horseback in the desert, Kate can be found gardening, making her own hot sauce, tending to her cows and chickens, and enjoying quality family time.
