About Us

Nursing Staff

Our nursing units are staffed by nurses, therapists, technicians and support staff who've dedicate themselves to excellence in the care of patients with total joint replacement. The staff offers a multidisciplinary approach to care and creates an environment that provides satisfaction for patients, families and employees. Many of the staff have been with Dr. Dorr for many years and have been instrumental in the development of the care plans. They have in-depth knowledge of the physicians' protocols and patient needs. They also participate in ongoing education and research. A comprehensive approach is fostered in which the care delivered is a continuation of the pre-operative preparation started in the clinic and looks toward the discharge goals to be achieved at home. Satisfaction has been demonstrated by recent survey scores. In that survey, patient willingness to return and employee job satisfaction both rated at 100%. We are very proud of our staff and the excellent care they provide our patients.
