Administrative Staff

Nancy Kent-Barber
Bariatric Patient Support Facilitator
As a patient who underwent successful gastric bypass surgery, Nancy brings a unique understanding of the challenges facing morbidly obese individuals seeking a bariatric surgery solution. Nancy brings her strength, understanding and compassion to help patients successfully manage their journey through insurance authorization, preoperative evaluation and postoperative follow up. Nancy organizes and maintains several components of our support program including tri-monthly support group meetings and several annual events. Nancy has been recognized by the American Association of Metabolic and Bariatric Surgery for her dedication and organizational skills. Nancy’s efforts were particularly noteworthy when she was recognized in 2008 for having successfully raised more than $15,000 as charitable contributions for obesity related research. Her efforts resulted in Ventura Advanced Surgical Associates being recognized as one of the top ten fundraisers for obesity research during the 2008 “Walk From Obesity” national event.
As a dedicated advocate for bariatric surgery patients, Nancy assists patients by meeting them at the hospital on their day of surgery and staying with them until they are brought back to the operating room. In addition, she coordinates our “Angels” support group by matching interested patients with a successful bariatric patient who can provide one on one support and encouragement during the early postoperative period.
Becky Shipp
Practice Manager
Becky is usually the first person patients talk to when calling our office. In addition, she is the first person most patients meet when coming to our office for their initial consultations. Coordinating the multiple appointments and tests each patient is asked to undergo is a challenge Becky has undertaken and mastered. Becky brings with her an understanding of the complexities of scheduling patients which allows us to provide consultations and care to the hundreds of patients each year who undergo clinical consultations, sleep medicine evaluations, bariatric and other surgical procedures. Her compassion and ability to organize and adapt to the needs of our patients allows most patients to experience a smooth transition through the evaluation process.
