Dr. John A Clark has the following 2 specialties

  • Nephrology

    A nephrologist is a physician who is specially trained to diagnose and treat conditions affecting the kidneys or renal system.
    A nephrologist will determine through urine analysis, blood test, X-ray, sonogram, or kidney biopsy how well the kidneys are functioning and will then prescribe a special diet and exercise program, medication or dialysis - a process by which a machine filters the blood when the kidney is no longer capable of doing so.

  • 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.

I have been a patient of Dr. John Clark for four & a half years. During that time, I have found Dr.Clark to be not only an excellent physician but a sincere & likable man. I am not the easiest patient to treat. I am in Chronic Renal Failure & have other serious conditions which complicate my medical treatment. These concurrent conditions create a situation which some physicians have found difficult, beginning with the management of the number of conditions & contrindications that come with handling my healthcare. Yet somehow, Dr. Clark has managed my medical situation, & he managed it with confidence & in good grace. Dr. Clark always discusses my situation in a straight forward manner and takes the time to explain the most complicated of medical details with patience. Even when the topic became difficult, Dr. Clark found a way to handle it with compassion. I have recomended Dr. Clark to others who are in need of renal care. I can't say enough about what a wonderful doctor he is. I truly respect Dr. Clark & am extremely grateful to have have him as my physician.
