Dr. Keenen’s office, Pacific Spine Specialists, is a top spine surgeon practice located in the Portland Oregon area. Dr. Keenen is highly experienced with minimally invasive spine procedures, motion preservation surgeries (cervical and lumbar artificial discs), micro-discectomy, cervical fusion, and lumbar fusion. After 20 years’ experience as a deformity surgeon, performing thousands of simple to highly complex spine surgeries, along with teaching 8 years on the faculty at Oregon Health Sciences University, he is committed to ensuring patients receive the proper diagnosis and the most effective surgery to achieve optimal function and pain relief.

He performs spine surgery at Providence and Legacy Hospitals, and the South Portland Outpatient Surgical Center. Dr. Keenen is proud to have successfully implemented the first JCAH-certified spine center in Oregon.
