DSSP Interventional Spine and Musculoskeletal Medicine Fellowship

Thank you for your interest in the DSSP fellowship. We are a NASS Recognized Interventional Spine and Musculoskeletal Medicine Fellowship. Our twelve-month PM&R based program strives to provide comprehensive interventional spine, sports, and musculoskeletal education in a private practice setting that stresses ethical and evidence-based medicine. We have five board-certified PM&R physicians who practice out of three offices in Phoenix, Scottsdale and Mesa which include fluoroscopic procedure suites and on-site physical therapy.

Program Description

We select one to two fellows each year who start their training in July with flexibility of the start date pending the approval of the Fellowship Director. Each fellow works directly under the supervision of a DSSP physician. A typical week consists of a blend of both outpatient clinic including patient evaluations, electrodiagnostic studies, ultrasound guided injections and PRP as well as fluoroscopic spine and joint procedures. The fellow also presents 1-2 articles at our monthly journal club which includes physical therapists and medical professionals from the community, and delivers a monthly lecture to the practice on a Spine or Musculoskeletal Medicine topic.


Requirements for application to the DSSP fellowship include the following:

  • Completion of an ACME-accredited residency program in PM&R
  • ABPMR board-certified or eligible
  • NASS application (click here for form)
  • Personal Statement
  • Curriculum Vitae
  • Three letters of recommendation

Applications should be emailed to Kathryn Meloy, DSSP Practice Administrator at kmeloy@dsspaz.comApplications will be accepted starting on January 4, 2021. After completed application materials are received, we will review the materials on a monthly basis and contact selected residents for an interview. The interviews will be conducted between March 23rd and July 24th 2021. A brief first round interview will be conducted with the fellowship director, Susan Sorosky MD over Zoom. If applicable, a second round interview will then be offered to the applicant either in-person or via Zoom (pending travel guidelines pertaining to COVID and the applicant’s immunization status). Typically the in-person interview will take place over two days with time spent with physicians and fellows in the clinic and the procedure suite in all three offices. Our fellowship is NASS-recognized and will abide by the Match Day of July 28th, 2021.  Applicants can access the NASS timeline on their website – spine.org.
