David Gregory, MD in Oklahoma City: Gastroenterology with Established Local Practice
David Gregory, MD is a gastroenterologist in Oklahoma City providing diagnostic and therapeutic endoscopy, colonoscopy, and management of digestive disorders at a private practice scale. He represents the independent gastroenterology option in a market dominated by hospital-affiliated specialists and multistate gastroenterology networks.
What He Actually Is
Gregory operates as a solo or small-group independent practitioner, distinct from the larger gastroenterology services embedded in OU Medicine, Mercy, and Integris Health systems. This model typically means more flexibility in scheduling and a continuity relationship with one physician rather than rotation through a group, though it also means the practice handles its own billing and does not have hospital infrastructure for complex inpatient cases.
Services and Scope
A gastroenterologist in private practice handles:
- Upper endoscopy (EGD) for evaluation of reflux, ulcers, dysphagia, and treatment of bleeding or strictures
- Colonoscopy for colorectal cancer screening and polyp removal
- Diagnostic tests such as H. pylori testing, fecal calprotectin, and other lab-based evaluations
- Management of irritable bowel syndrome, inflammatory bowel disease, and functional disorders
- Esophageal manometry and other motility studies, depending on office capability
Pricing for gastroenterology services is highly variable and depends on insurance negotiation. Out-of-pocket colonoscopy screening in Oklahoma typically ranges from $800 to $1,500 at independent practices when uninsured, but most insured patients pay nothing for preventive colonoscopy under the Affordable Care Act; confirm your specific copay or coinsurance with the office before scheduling. Therapeutic procedures (polyp removal, biopsy) or upper endoscopy cost more and are often subject to deductibles. Verify current charges with the practice directly, as facility fees and anesthesia costs change.
How He Compares to Other Oklahoma City Options
Oklahoma City's gastroenterology landscape splits between hospital-employed specialists and independent practitioners. OU Medicine Gastroenterology and Mercy Clinic Gastroenterology operate as part of larger systems, offering integrated hospital access, multispecialty referral networks, and 24/7 inpatient support. That structure is essential if you have complex inflammatory bowel disease, require hospitalization, or want same-system coordination with your primary care. However, wait times at large systems average 4 to 8 weeks for routine colonoscopy screening.
An independent gastroenterologist like Gregory typically offers shorter appointment availability (often 2 to 4 weeks) and a single physician continuity model. The trade-off is that if hospitalization or emergency endoscopy is needed, he will refer you to a hospital partner rather than having direct institutional resources. This suits straightforward screening, diagnostic follow-up, and stable chronic management but is less ideal if you have acute bleeding, severe IBD flare, or complex interventional needs.
Who It Suits and Who It Does Not
Choose an independent gastroenterologist for:
- Preventive colonoscopy screening with preference for one consistent physician
- Management of stable GERD, IBS, or functional disorders
- Follow-up of known polyps or previous findings
- When scheduling speed matters more than hospital infrastructure
Choose a hospital-affiliated gastroenterologist if you have:
- Active inflammatory bowel disease requiring specialist coordination and possible hospitalization
- Suspected acute GI bleeding or severe symptoms
- Need for advanced interventional procedures (stricture dilation, ERCP, Barrett's esophagus management)
- Desire for integrated inpatient gastroenterology services
What the First Visit Involves
A new-patient gastroenterology appointment typically runs 30 to 45 minutes. The physician will take a detailed history of digestive symptoms, medication use (particularly NSAIDs, aspirin, and anticoagulants), and prior GI procedures. Review of systems includes red-flag symptoms such as weight loss, chronic pain, or changes in bowel habits. If a colonoscopy is planned, you will receive detailed bowel-prep instructions (typically polyethylene glycol solution consumed the day before) and sedation consent. Confirmation of insurance benefits and cost responsibility happens at check-in; bring your insurance card and a list of current medications.
Hours, Parking, and Getting There
Verify hours and location directly with the practice office, as independent physician practices often adjust scheduling seasonally and by provider availability. Most gastroenterology offices are open weekdays during business hours with limited or no evening or weekend slots. Parking is typically office-lot or street parking; confirm before your appointment if mobility or accessibility is a concern. Colonoscopy and upper endoscopy require someone to drive you home, as sedation rules prohibit driving for 24 hours after the procedure.
David Gregory's independent practice position reflects the demand for straightforward gastroenterology care in Oklahoma City without the layers of a large health system, though that same structure makes him a poor fit for acute or complex cases.
