Dr. John Greifenkamp has the following 2 specialties

  • 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.

  • Geriatric Medicine

    A geriatric specialist is a physician who treats the elderly population and the conditions that most commonly affect them. These doctors have special training in the effects of aging on the body and mind of a patient.
    Geriatric specialists treat common ailments faced by senior citizens, such as frailty, incontinence, memory problems, arthritis, senility, decreased functioning and more.
    In addition, geriatric specialists keep abreast of the different medications that an elderly person is prescribed to treat their more complex health issues in order to decrease adverse side effects and avoid dangerous drug interactions.
