Ventura Advanced Surgical Associates – Comprehensive Metabolic Evaluation and Treatment

Specialists in minimally invasive surgery and the evaluation and treatment of obesity-related medical diseases.

Dr. Billy and his team of medical and clinical professionals provide a unique combination of outstanding medical evaluation and surgical management of a variety of medical problems related to metabolic syndrome and morbid obesity. Our combined approach of bringing medical and surgical evaluation under one roof allows patients to undergo most of their entire preoperative medical evaluation at one location. Dr. Helmuth Billy is the leading laparoscopic sleeve gastrectomy and laparoscopic gastric bypass surgeon in Ventura and Santa Barbara Counties. Dr. Billy is a board-certified general surgeon and a member of the American Society for Metabolic and Bariatric Surgery. He is the Director of Bariatric Surgery at both Ventura Advanced Surgical Associates and St. John’s Regional Medical Center in Oxnard, CA.

Under the direction of Dr. Andrew Binder, patients can receive their entire preoperative cardiac, pulmonary and medical evaluations safely and conveniently. Ventura Advanced Surgical Associates also offers nutritional evaluation and counseling, preoperative psychological evaluation and postoperative support, and DEXA bone densitometry.

At Ventura Advanced Surgical Associates our mission is to treat the entire patient not only focusing on their obesity but all the problems that it can cause. In addition to the medical diseases related to obesity, there are also symptoms related to hormone imbalance and damaging effects to the skin, veins and unwanted hair growth. We address these effects in two ways. First, a registered dietician provides an integrative approach to diet and nutrition with an emphasis on science, eating style and overall health and wellness. We also offer an onsite MediSpa featuring the Cutera Laser System. With this system, we are able to effectively treat any skin type patient. We are able to address their acne and acne scarring, and safely remove unsightly hyperpigmentation and excess hair growth. The laser system also allows us to safely and non-surgically tighten skin on the face, neck, arms, and abdomen.

Ventura Advanced Surgical Associates Headquarters is located in Ventura, California. Our 6500 square foot facility was designed specifically to incorporate a myriad of important medical, surgical and rehabilitation services under one roof where patients could obtain the full spectrum of their care with confidence and trust that their care was not only state of the art but the most comprehensive and inclusive care available.

If you want to learn more about Dr. Billy, the program and the treatment of obesity, we strongly encourage you to attend one of our FREE educational seminars. Attending a seminar is the first step, and we will be with you for every step thereafter as you begin this journey into the rest of your life.
