Colonoscopy
Colonoscopy is an endoscopic procedure examining the colon for abnormalities like polyps. Using a flexible tube with a camera, our gastroenterologists detect and remove precancerous growths under sedation. This preventive care service helps reduce colorectal cancer risk through early detection.
Endoscopic Ultrasound
Endoscopic ultrasound combines endoscopy and ultrasound imaging to examine digestive tract structures. Our specialists use this technique to evaluate pancreatic disorders, bile duct issues, and submucosal lesions with high-resolution imaging for accurate diagnosis and staging.
ERCP
ERCP diagnoses and treats bile duct and pancreatic disorders through a specialized endoscope. Our team addresses obstructions, removes stones, and places stents during this minimally invasive procedure that combines diagnostic imaging with therapeutic interventions.
Weight Loss Programs
Our comprehensive weight loss programs combine medical supervision with nutritional guidance. The Ideal Protein program and other evidence-based approaches address obesity-related health risks through personalized plans developed by gastroenterology specialists.
Capsule Endoscopy
Capsule endoscopy uses a swallowable video capsule to examine the small intestine. This non-invasive procedure captures detailed images of the intestinal lining to diagnose obscure gastrointestinal bleeding, Crohn's disease, and other small bowel disorders.

Be absolutely sure this facility is actually in network with your insurance company. After referral here by my PC, I made an appointment, at which time my insurance info was taken. The appointment was on June 2nd. Upon checking in on day of appointment, my insurance info was again taken, and I was charged the appropriate co-pay. I consulted with a doctor for a colonoscopy, which was then set for two weeks later.
Good to go, right? Nope, I got a phone call from billing the next day saying that the facility was NOT in network with my insurance. Kind of seems like that would be important for them to know and to tell me BEFORE I saw the doctor. What a complete waste of time! I lost several months waiting to see the doc and now must start from square one. Their response? "We're not sure why that happened."

Dr M Moore has changed my life. I have been in remission with my UC for going on 4+ years now thanks to him and Humira. He's the kindest, most personable Doctor around and I would recommend him to anyone who struggles with any type of gastrointestinal issues. He definitely makes sure you receive the best care and answers any concerning questions you may have. It's great to have a doctor who actually fights to find the best solution for whatever your situation may be.

Dr. Ergen is quite possibly the most arrogant doctor I've had the displeasure to see. He barely listened, would interrupt frequently and generally bullied his way through the visit. The entire visit felt like shopping for a used car. It always felt like he was trying to sell something. His nurses scheduled appointments without notice then got upset when those appointments were missed. The overall atmosphere of the clinic is cold. I never felt like anything more than a number attached to an insurance check.

I was a patient at this medical facility for over 2 years. I was initially seen by Dr. Chobanian, but switched to Dr. Samavedy more recently after I felt I was not being taken care of adequately. After switching to Dr. Samavedy, my experience was even worse. I feel that he had already made a decision and a plan before assessing me and from reviewing my medical records from Dr. Chobanian 2+ years prior.
I tried to explain that my condition has significantly worsened during the last year, but wasn't listened to at all. During my appointment, I was talked over and practically dismissed. I was told, "not everything is a GI problem, " after explaining symptoms that I was worried about. I left the office and cried in my car. I've spent so much money here on testing and scopes to get zero answers or good suggestions.
I made a decision at that point to switch practices entirely. I would not recommend wasting your time or money here. Edit: After switching to Edmund's Gastroenterology, I was told the issue I was complaining about that, "wasn't a GI issue, " was in fact a different type of reflux and I'm now taking medication that has improved the condition significantly.
