Advanced Gastroenterology, Inc

555 Marin Street, Thousand Oaks, CA 91360

"Dr. Gilbert Simoni runs a very very good office! Five stars all around to the Doctor and the front desk. He made everything feel safe and under control, I've seen other doctors before for similar issues but he was very thorough and explained the steps and solutions. I will recommend friends and family to Advanced Gastroenterology, Inc."

"As always I am very satisfied with a whole staff at Dr Simoni office. So glad that I can do my endoscopy at the office and it’s very quick and very professional by Dr Simoni."

"This review is written with the understanding that my request to see the doctor at Advanced Gastroenterology, Inc occurred during the 2023 holiday season and that staffing was at a minimum. Nevertheless, the lack of response from this facility when I clearly noted this was an urgent situation is unacceptable, especially for a facility touting its expertise in interventional gastroenterology. On December 22, 2023, I was seen at the Los Robles ER for a continuous painful abdomen. After CT and ultrasound scans, the ER found my liver enzymes were out of range, I had a distended common bile duct as well as an undefined pancreatic cyst. The ER urgently recommended I see a GI specialist for follow-up. I contacted AGI on December 26 and sent them my ER records as they requested. I was informed the doctor would review them and that AGI would then get in touch to let me know if they could take me as a new patient. On December 27, still hearing nothing from AGI even though I had noted the urgent nature of my contact, I could not wait any longer and made contact with Cedars-Sinai Hospital where I knew the staff would be attentive, professional and concerned about providing the best care possible. After a few phone calls within about 2 hrs, including the exchange of the noted ER records, I was scheduled the next morning for an EUS/ERCP. During this procedure, the findings of the ER were confirmed, the medical team performed a sphincterotomy and cleared the CBD, and made a referral for a potential future cholecystectomy. Three weeks later (Jan. 14) I still have heard nothing from AGI. Apparently “interventional gastroenterology” means when they “get around to it” rather than recognizing the urgency often surrounding that term and how a delay affects the patients health and well-being. Given my experience, I can not recommend this facility."

"The staff was pleasant, however I don't know how they can work for a doctor who is so heartless. My son had 3 or 4 visits and never met Dr Sumoni until the day of his procedures. Even the nurses at Los Robles were surprised we hadn't met him. My son had been in severe pain and was looking for any kind of relief. He asked Dr S to prescribe him something he researched that might help with pain. Dr S threw a tantrum and said find another doctor. He left my 19 yr old , depressed son in a compromising position and to top it off, Never gave us the results of his colonoscopy and endoscopy as he said he would do right away. This doctor should be ashamed of himself...he is a robot, not a caring physician. Per Dr S's response....you wouldn't know the truth because you weren't involved. A young adult, 19yrs old...you kicked to the curb. Maybe take a step back and wonder why you have other, similar reviews."

"Dr. Simoni and his entire team genuinely care about your good health and getting you healed! Appointments and accessibility to reach the office are easy and immediate, every facet of staff is very kind and knowledgeable, and Dr. Simoni is absolutely wonderful! He's a great listener with complete eye contact while hearing about your ills, and his experience will help get you back on track again right away. This is where you want to go to get your problem fixed correctly, the first time!"
