Who Will Treat My Injuries?

Crystal Clinic QuickCare is led by Robert Kleinman, M.D., an orthopedic specialist with over three decades of experience in the diagnosis and treatment of musculo-skeletal conditions and injuries. His support staff includes other orthopedically trained providers such as physician assistants (PAs), physical and occupational therapists, radiology technicians and nurses.

In the event that Dr. Kleinman is unable to treat you, you will be seen by either a PA or nurse practitioner (NP). PAs and NPs work in all areas of medicine, including primary care and family medicine, emergency medicine, orthopedics and psychiatry. All are trained to diagnose, treat and prescribe medication for acute and chronic orthopedic conditions.
