- Yes. We see patients from across the Central Valley including Clovis, Madera, Visalia, Selma, Sanger, Reedley, and Kerman.

- What insurance do you accept?
- We accept most major insurance plans, including Medicare. Call our office at (559) 299-9395 to verify coverage for your specific plan before your visit.
- What does a gastroenterologist treat?
- Gastroenterologists specialize in the digestive system — esophagus, stomach, intestines, colon, liver, and pancreas. We focus on colon cancer screening, colonoscopy, flexible sigmoidoscopy, upper endoscopy (EGD), and stool-based screening tests.
Colonoscopy & prep
- When should I get my first colonoscopy?
- Average-risk adults should start screening colonoscopies at age 45. If you have a family history of colon cancer or polyps, inflammatory bowel disease, or symptoms like rectal bleeding or a change in bowel habits, you may need to start earlier — call (559) 299-9395 to discuss.
- How long does a colonoscopy take?
- The procedure itself usually takes 20–45 minutes. Plan on being at our Fresno facility for about 2–3 hours total: check-in, IV sedation, the procedure, and recovery. You'll need a driver to take you home.
- Are you awake during a colonoscopy?
- No. We use IV sedation (typically propofol) so you are comfortably asleep for the entire procedure. Most patients don't remember anything about it and wake up in recovery feeling rested.
- How much does a colonoscopy cost in Fresno?
- For most insured patients, a screening colonoscopy is covered at 100% with no out-of-pocket cost under the Affordable Care Act. Diagnostic colonoscopies are subject to your normal copay or deductible. We verify your benefits before scheduling.
- What can you not eat 5 days before a colonoscopy?
- Starting 5 days before, avoid high-fiber foods: nuts, seeds, popcorn, raw fruits and vegetables, whole grains, brown rice, beans, lentils, corn, and anything with skins or hulls. Stick to a low-fiber diet of white bread, white rice, plain pasta, well-cooked peeled vegetables, tender meats, and eggs.
- What can I eat the day before a colonoscopy?
- Clear liquids only — no solid food. That includes water, clear broth, apple or white grape juice, plain coffee or tea (no milk), Jell-O and popsicles in yellow, orange, or green, and sports drinks. Avoid anything red, purple, or blue, and anything with milk or pulp.
- Why can't I have red, purple, or blue liquids before my colonoscopy?
- Red, purple, and blue dyes can stain the lining of the colon and look like blood during the procedure, making it harder for your doctor to see clearly. That can lead to a false alarm — or a repeat colonoscopy.
- What can I eat after my colonoscopy?
- Start with light, easy-to-digest foods: water, clear broth, crackers, toast, plain rice, applesauce, and bananas. Most patients return to a normal diet the next day. If a polyp was removed, your doctor may ask you to avoid nuts, seeds, popcorn, and alcohol for a few days.
- Where can I get a detailed prep guide?
- We publish a full day-by-day colonoscopy prep guide with food tables for what to eat and avoid 5 days before, 2 days before, the day before, and after your procedure. Visit /colonoscopy-prep on our site or call (559) 299-9395 with questions.
