The 10 Best Gastroenterologists in Katy, TX

James Maher’s practice makes a specific promise: he handles the consultation, procedure and results himself. That setup can suit a patient who wants one doctor to own the handoffs. The practice also lists on-site FibroScan and says urgent new-patient visits may be available within the same week. Confirm the schedule when you call.

Memorial Hermann lists board certification in internal medicine and gastroenterology, plus training in hepatology and GI. His scope covers reflux, inflammatory bowel disease, colonoscopy, upper endoscopy and liver disease. The Texas Medical Board record lists license F1131 as active with disciplinary status NONE.

The office sits on Park Row in Houston, just east of Katy. Its Google feedback is less even than several local listings below, so ask direct questions about wait time and follow-up. Before a procedure, get the facility name and confirm that the doctor, lab, anesthesia team and center are in network.

Pritesh Mutha is the most procedure-focused choice in this group. McGovern Medical School names him director of Third Space Endoscopy. Memorial Hermann lists EUS and ERCP for pancreas and bile-duct problems, POEM for some swallowing disorders, and ESD or EMR for removing certain growths through a scope.

His official profiles list board certification in internal medicine, gastroenterology and lifestyle medicine. He practices at a Cinco Ranch office and is affiliated with Memorial Hermann Katy Hospital. That combination gives Katy patients a local clinic and an academic referral path for harder cases.

The doctor-only Google page had three reviews when checked, far too few for a useful pattern. Concentrate on the procedure your referring doctor requested. Ask where it will happen, who will perform it and whether old scans or scope reports must arrive before scheduling.

Murtaza Arif has the clearest mix of a central Katy office, broad GI work and a large doctor-specific review sample. Houston Methodist lists board certification in internal medicine and gastroenterology, therapeutic-endoscopy training at Geisinger Medical Center and an affiliation with Houston Methodist West.

The office handles colon screening, reflux and common bowel problems. Houston Methodist also lists English, Hindi and Urdu, with a warning that a language may be spoken by the doctor or office staff. Ask who will interpret during the visit if language access matters to you.

A colonoscopy can produce separate bills from the doctor, procedure center, anesthesia team, pathology lab and pharmacy. Get the center name before booking, then check each likely charge with your insurer. Bring prior scope reports and a current medicine list to the first visit.

Radha Tamerisa’s practice puts nutrition and weight beside standard gastroenterology. Her practice biography calls her a board-certified gastroenterologist. Rice Business identifies her as certified in both gastroenterology and obesity medicine, with more than 20 years in practice.

That focus may help when reflux, weight or fatty liver overlap. Her doctor-led Google listing also had the largest review sample in this guide. We used those reviews to assess office service only. They do not establish whether a nutrition or weight plan will work for one patient.

Ask which services count as covered medical care. Nutrition visits, weight treatment, testing and supplements can follow different benefit rules. A useful plan should name the goal, the measure used to track it and the date for follow-up.

Houston Methodist’s physician roster places Hani Zamil on its West interventional-gastroenterology team at 18300 Katy Freeway. The West Houston group page lists care for swallowing problems and disease of the pancreas, gallbladder and bile ducts.

The current hospital site does not publish an individual biography for him, so we did not score old directory claims as verified training facts. His Texas license M9767 was active with disciplinary status NONE when checked, and the current group roster supports calling when another doctor recommends interventional GI care.

The office is in Houston, and the doctor-specific Google sample was small. Ask the scheduler for the exact planned procedure, facility and billing codes because a hospital-campus test can carry a separate facility charge.

Ting-Hui Hsieh has the deepest liver training in the ranking. Memorial Hermann lists Mayo Clinic fellowships in gastroenterology and transplant hepatology, a Memorial Hermann Katy affiliation, and interests that include fatty liver, hepatitis and cirrhosis.

Houston Gastro Institute reports gastroenterology certification in the United States and Taiwan, more than 20,000 procedures, and service in English, Mandarin and Taiwanese. Those practice-reported figures sit beside a Texas Medical Board record that lists license V3325 as active with disciplinary status NONE.

The review number belongs to the shared practice page, so it describes the office more than either doctor. For long-term liver care, bring old lab trends and imaging reports. Ask which result will show whether treatment is working. Get the date for the next check before leaving.

Kevin Marks is certified in gastroenterology and obesity medicine, according to his practice profile. His Baylor fellowship covered gastroenterology, hepatology and advanced therapeutic endoscopy; he has practiced since 2006 and lists colon cancer prevention, reflux, pancreas and bile-duct disorders, liver care and weight management.

The practice and Memorial Hermann both give the current address as 521 W. Grand Parkway South. Houston Methodist still shows an older address on North Grand Parkway, so call before driving; Memorial Hermann lists its Katy hospital affiliation, while the practice also lists Houston Methodist West.

The Google rating belongs to Premier Gastroenterology, not Dr. Marks alone. If fatty liver and weight are part of the visit, ask for a measurable target. Get a date to repeat labs or imaging. Check whether nutrition or obesity services use the same insurance benefits as the GI visit.

Moazzam Sana is a doctor of osteopathic medicine. The Texas Medical Board, Memorial Hermann and Texas Digestive Disease Consultants identify him as Moazzam Sana, DO. His license N9124 was active with disciplinary status NONE when checked.

TDDC lists gastroenterology certification and advanced interventional-endoscopy training at Baylor Scott & White. His procedure list includes EUS, ERCP, upper endoscopy, colonoscopy and capsule endoscopy. The Katy office sits in LaCenterra, while Memorial Hermann lists an affiliation with its Sugar Land hospital.

Ask which days he sees patients in Katy and where a procedure will take place. A group with several offices can offer more referral options, but the clinic, hospital and endoscopy center may sit in different parts of the metro.

Andrzej Janecki runs an independent office on Katy Freeway. The Texas Medical Board lists license K8232 as active with disciplinary status NONE, and AMA Find a Doctor confirms gastroenterology and the current Katy address.

The practice site publishes little credential detail, so we scored only what current public records support: an active Texas license, gastroenterology as his specialty and the Katy address. That narrower record is why he sits below doctors with fuller official profiles.

The exact doctor-and-practice Google page had more than 200 reviews when checked. Before booking, confirm the new-patient wait, accepted insurance and procedure center with the office. Directory insurance lists often lag behind contract changes.

Vivian Asamoah combines standard gastroenterology with prevention, nutrition and lifestyle work. Memorial Hermann confirms board certification in internal medicine and gastroenterology, a Johns Hopkins fellowship and a Katy hospital affiliation. Houston Methodist also lists her with its West hospital.

Her stated clinical interests include colon screening, reflux, bowel disorders, weight and fatty liver. Memorial Hermann says immediate or same-day appointments may be available. Access can change quickly, so confirm it when you call.

The doctor-only Google page had ten reviews and a mixed score. The shared practice page was much stronger, but those are two different records. Ask how long a first visit lasts, who explains results and which nutrition services fall under your plan.
