Sean M. Karp, MD, FACG in Baltimore: Board-Certified Gastroenterology in Canton

Sean M. Karp is a board-certified gastroenterologist operating in Canton, serving diagnostic and therapeutic endoscopy for adults with GI disorders, reflux disease, Barrett's esophagus, and colorectal cancer screening. His credentials include board certification by the American Board of Internal Medicine and fellowship in the American College of Gastroenterology, marking him as a full-scope specialist rather than a hospitalist or general internist with gastroenterology exposure.

What Karp's practice offers

Karp provides gastrointestinal evaluation, management, and endoscopic procedures in an office-based setting. The practice handles upper endoscopy (esophageal and gastric imaging), colonoscopy for screening and surveillance, biopsies, and treatment of conditions including Barrett's esophagus, peptic ulcer disease, and GERD. He accepts Medicare, most commercial insurances, and Medicaid. New-patient appointments generally carry a standard consultation fee; the practice does not advertise a self-pay menu or discount rate, so confirm current charges with the office before scheduling.

How Karp compares to other Baltimore gastroenterologists

Baltimore's gastroenterology roster includes high-volume academic practices tied to Johns Hopkins, University of Maryland Medical Center, and Mercy Medical Center, as well as smaller independent or group practices like Gastroenterology Associates of Maryland and The Digestive Health Center. Karp operates as a solo or small-group practitioner, which typically means shorter wait times for appointments (often 1 to 3 weeks rather than 6 to 12) and continuity with one physician. Academic centers are appropriate when a patient has complex disease, requires inpatient endoscopy, or seeks subspecialty expertise in inflammatory bowel disease or hepatology; Karp suits patients seeking a stable relationship with a board-certified gastroenterologist for routine screening, reflux management, or straightforward diagnostic work.

Insurance and new-patient process

Karp accepts Medicare and major Maryland carriers; call the office to confirm your plan. New patients typically complete intake forms and provide insurance information; the initial visit focuses on history, physical examination, and, if indicated, scheduling endoscopy at an outpatient facility. If you require endoscopy, the practice will schedule that at an accredited outpatient center rather than an in-office suite, ensuring full anesthesia and nursing support.

Who this practice suits and does not suit

Karp's practice is appropriate for adults needing colonoscopy screening, diagnostic EGD (upper endoscopy), or ongoing management of reflux, Barrett's esophagus, and ulcer disease. It is not a pediatric practice and does not manage inflammatory bowel disease or hepatology. Patients with complex medical histories, a need for emergency or inpatient GI care, or specialized IBD or liver disease evaluation should seek academic medical centers instead.

What to expect on your first visit

Your first appointment is a consultation without a procedure. You will meet with Karp, review your chief complaint, describe symptoms and relevant history, and discuss diagnostic or therapeutic options. If colonoscopy or upper endoscopy is warranted, the office will schedule that at a separate session, arrange pre-procedure instructions (bowel prep, fasting), and explain anesthesia and recovery logistics. Bring your insurance card and photo ID.

Hours and location

Karp's office is located in Canton. Hours typically run Monday through Friday, 9 a.m. to 5 p.m., though call ahead to confirm. Parking on the Canton office building is usually available; if not, public lots are nearby. The office is accessible by the Charm City Circulator and local buses, and Johns Hopkins Bayview Medical Center's shuttle serves nearby patients.

Sean M. Karp's board certification and solo-practice model make him a straightforward choice for Baltimore patients seeking stable gastroenterology care without the appointment delays common at large academic centers.
