Fourth Corner Neurosurgical Associates was founded in 1988 to serve the northwest corner of Washington. In 2007, we completed our new building, The Cascade Brain and Spine Center. The modern 24,000 sq.ft. structure is located a few blocks from our regional hospital and the specialist medical community. Fourth Corner Neurosurgical occupies nearly 9000 sq. ft. and leases space to several synergistic services.
