DNA physicians have primary commitments to assigned hospitals and are thus available to serve as consultants for a wide variety of renal problems.  The physicians are involved in the evaluation and care of patients with disorders affecting kidneys, such as hypertension, hematuria, proteinuria, electrolyte disorders, kidney stone formation, and glomerulonephritis. Most all supervise in-hospital dialysis.  In some cases hospital practice also involves the teaching of internal medicine residents and renal fellows.  Several of the physicians have received awards for their excellence in teaching.
