We also care for patients pre- and post-kidney transplant and manage the treatment of patients with hypertension. You can count on us to provide consultation, screening, education, and treatment, dialysis care, and hospital care, if needed, such as continuous renal replacement therapy and dialysis for end-stage renal disease.
