Ventura Advanced Surgical Associate

What Ventura Advanced Surgical Associate does

Ventura Advanced Surgical Associates is a private, independent bariatric and general surgery practice headquartered in a 6,500 square foot facility at 3200 Telegraph Road in Ventura, California, founded in its current form in 2002 when Dr. Helmuth Billy relocated from Northern California. The practice specializes in laparoscopic and robotic-assisted (da Vinci) weight-loss surgery, offering gastric bypass, sleeve gastrectomy, lap band, and revision procedures, and serves patients with a BMI of 40 or higher, or BMI of 35-39.9 with weight-related comorbidities, across Ventura and Santa Barbara Counties. Surgical care is delivered through two affiliated hospital Centers of Excellence (St. John's Regional Medical Center in Oxnard and Community Memorial Hospital in Ventura), both recognized by Medicare, Blue Cross, Blue Shield, Health Net, and Kaiser Permanente.

The practice operates a multi-disciplinary model that co-locates a Board Certified Pulmonologist and Sleep Medicine Specialist, a Psychologist, a Certified Bariatric Nurse, a Registered Dietician, and front-office and billing staff under one roof, supplemented by an 8-week Lifestyle Wellness Program, monthly support groups, and a patient portal hosted on AdvancedMD. Beyond bariatrics, the practice generates revenue from general surgery (hernia repair, cholecystectomy, antireflux, colon, and other laparoscopic and robotic-assisted abdominal procedures), sleep medicine (overnight sleep studies, CPAP, oral appliances), and GLP-1 weight loss injections for both surgical and non-surgical patients. Patient acquisition runs primarily through free educational seminars, physician referrals, and word-of-mouth, supported by a 4.9/5 star rating across 373 reviews on Google, Vitals, ObesityHelp, and Healthgrades.

Revenue is generated on a fee-for-service professional services model, billed through insurance with patient responsibility for any uncovered balance; the practice is a preferred provider with Blue Cross, Blue Shield, Health Net PPO, Kaiser Permanente, Aetna, Cigna, and Gold Coast MediCal, and offers financing through Prosper Healthcare Lending for uncovered surgical fees. Practice leadership is centered on Dr. Billy (lead bariatric surgeon), Dr. Andrew Binder (sleep medicine), Samantha Billy (Corporate Administrator), and supporting clinical and administrative staff, with no disclosed parent company, institutional investment, or external funding.

Products and services

• Gastric Bypass Surgery A weight-loss procedure that creates a small stomach pouch and bypasses part of the small intestine to restrict food intake and reduce calorie absorption. Indicated for morbidly obese patients (BMI 40+ or BMI 35-39.9 with weight-related conditions).
• Sleeve Gastrectomy A surgical procedure that removes approximately two-thirds of the stomach, creating a banana-shaped tube that restricts food intake and decreases appetite. Weight loss continues for 2-3 years post-procedure.
• Lap Band Surgery A reversible gastric banding procedure that places an inflatable silicone band around the upper stomach to create a smaller pouch. Patients report average weight loss of 60 pounds maintained for up to 15 years.
• General Surgery Laparoscopic and da Vinci robotic-assisted surgical procedures including hernia repair, cholecystectomy, antireflux surgery, colon surgery, esophagus surgery, liver surgery, stomach surgery, pancreas surgery, adrenalectomy, splenectomy, nephrectomy, and emergency laparoscopy.
• Revision Surgery Complex revision weight-loss surgery procedures including restoring stomach pouch size after gastric bypass, converting lap band to gastric bypass or sleeve, replacing lap bands, and duodenal switch procedures.
• Sleep Medicine Diagnosis and treatment of sleep apnea and other sleep disorders including overnight sleep studies, CPAP treatments, oral appliances, laser treatments, and surgical options for throat tissue.
• Weight Loss Injections (GLP-1) GLP-1 medication program that mimics the glucagon-like peptide-1 hormone to regulate hunger, fullness, and blood sugar for diabetes management and weight loss support for both bariatric post-surgery patients and new patients.
