Dr. John A Walker has the following 2 specialties

  • Gastroenterology

    A gastroenterologist is a specialist in diagnosis and treatment of conditions involving the digestive/gastrointestinal (GI) tract. These doctors are experts on how food moves through the digestive system and is chemically broken down, with nutrients being absorbed and waste excreted. You might see this kind of doctor if you are experiencing any number of stomach issues, some of which might be severe diarrhea, irritable bowel syndrome, hemorrhoids, ulcers, acid reflux, Crohn's disease and more.

  • Internal Medicine

    An internist is a physician who focuses on the diagnosis and treatment of conditions that affect the adult population—both acute and chronic.
    These doctors are often who adults see as their primary physicians because they treat a broad range of illnesses that do not require surgical or specialist interventions. They also work to help a patient maintain optimal health in order to prevent the onset of disease.
    In addition to treating the common cold and flu, internists also treat chronic diseases like diabetes and heart disease.

Horrible medical care

Initially went in for high liver enzymes, took a biopsy right off the bat and THREE hepc test after biopsy and first test negative. Adamant it was not my med when suggested. In the end and few thousand later told to drink a lot of coffee and lose weight. Stopped my statin and liver enzymes back to normal. Then never call me back to treat problem in esophagus. Months later email question since acid reflux getting worse and three week later get a call that they pre-auth aplasia procedure and no other info. Definitely not continuing with Walker

Took several weeks to get an appointment. Waited for an hour and half to see the doctor. Had procedure done and was assured that he would call with results in 7 - 10 days. Two weeks later still hadn't gotten results so went to his office and talked to staff who promised his nurse would call later that afternoon with results. No one called and when we called back the next day were told they don't work on Fridays. Total indifference to patients and their needs. Would never recommend this dr to anyone and will definitely be finding a new gastroenterologist!!!
