Credentials and training, verifiable in detail

Education timeline

Undergraduate: Bachelor’s degree, Yale University. Medical school: Doctor of Medicine (MD), Tufts University School of Medicine. Residency: Internal Medicine residency followed by Anesthesiology residency. Fellowship: Interventional Pain Medicine, University of Pennsylvania.

The educational trajectory reflects the dual-discipline foundation of interventional pain medicine — internal medicine training for the medical management context, anesthesiology training for the interventional procedure foundation, and IPM fellowship for the specific subspecialty focus.

Board certifications

American Board of Internal Medicine — board certified. American Board of Anesthesiology — board certified. Both certifications can be verified through the respective certifying boards’ public verification systems.

Board certification represents demonstrated competence in the specialty’s core knowledge and skills, as assessed by the certifying board’s examinations and ongoing maintenance-of-certification requirements. Dual certification across Internal Medicine and Anesthesiology is uncommon and reflects the specific career path through interventional pain medicine.

Practice and licensure

Active practice in Upstate South Carolina continuously since 1992. South Carolina medical license is current and in good standing — independently verifiable through the South Carolina Board of Medical Examiners.

The 30+ years of continuous practice in the same regional market means many patients have been referred from regional primary care physicians, orthopedic surgeons, and other specialists who have observed outcomes over time. The local professional network knows the work.

Professional memberships

North American Spine Society (NASS) — member. NASS is the leading multidisciplinary professional society for spine care; membership reflects active engagement in the field. American Association of Neurological Surgeons (AANS) — associate member.

Society memberships are an indicator of professional engagement, though not a credential per se. Active membership in the relevant societies — particularly NASS for spine practitioners — provides ongoing exposure to evidence updates, technique developments, and the broader professional community.

Verifying credentials independently

All of the above is independently verifiable through public sources. Medical board records confirm licensure status and any disciplinary actions. Certifying boards confirm certification status. Society directories confirm membership. Hospital systems confirm any current or historical privileges.

We encourage patients to verify credentials of any surgeon they’re considering — not just Dr. McMillan. The public verification systems exist for this purpose; using them is a reasonable due-diligence step before any significant medical decision.

Education and training

Undergraduate: Yale University. Medical degree: Tufts University School of Medicine. Internal Medicine residency followed by board certification in Internal Medicine. Anesthesiology residency followed by board certification in Anesthesiology — the dual-specialty foundation that’s relatively uncommon among practicing spine surgeons. Interventional Pain Medicine fellowship at the University of Pennsylvania during a period when the program was a leading academic center for IPM training.

Board certifications and verification

Dr. McMillan holds two board certifications: American Board of Internal Medicine and American Board of Anesthesiology. Anesthesiology certification includes subspecialty competence in pain medicine. The combined background informs surgical-decision-making about patients with significant comorbidities. Public verification is available through the American Board of Medical Specialties (ABMS) and the consumer-facing CertificationMatters.org service. State medical license verification is available through the South Carolina state medical board.

Professional society memberships

Dr. McMillan is a member of two principal U.S. spine professional societies. The North American Spine Society (NASS) — the largest U.S. medical society dedicated to spine care, founded 1984 — reflects active participation in the field’s professional development. The American Association of Neurological Surgeons (AANS) — the principal U.S. society for neurosurgery, founded 1931 — reflects cross-specialty recognition of spine surgery’s neurosurgical dimension.

Patents and clinical contributions

Dr. McMillan is the named inventor on two issued U.S. patents: 8,152,796 (2012) and 9,050,097 (2015). Full abstracts and granted claims are accessible through the USPTO public search. The patents reflect investment in technique refinement rather than off-the-shelf procedural adoption. Detail at /patents-and-publications/.

Continuing education and technique refinement

Board certification is a checkpoint, not an endpoint. The endoscopic spine surgery technique evolved substantially during the 2010s as European and Asian centers refined instrumentation and expanded procedural indications. Staying current requires ongoing engagement with the international spine surgery community — through NASS annual meetings, AANS educational programs, and direct exchange with the European and Asian centers where the technique matured earliest. Dr. McMillan’s continuing education participation extends beyond required maintenance-of-certification cycles into active engagement with the field’s technical evolution.

The two U.S. patents held by Dr. McMillan reflect this ongoing technique refinement rather than passive adoption of an off-the-shelf approach. Patent 8,152,796 (2012) predates the widespread U.S. commercial availability of full-endoscopic spine surgery systems by several years; the practice was performing percutaneous decompression procedures before the current generation of European-designed endoscopic instrumentation became standard in U.S. operating rooms. Patent 9,050,097 (2015) covers apparatus refinements developed through clinical experience with the earlier percutaneous approach. Both patents are documented in detail at /patents-and-publications/.

State licensure and clinical privileges are maintained through the South Carolina Department of Labor, Licensing and Regulation. Public license verification is available at llr.sc.gov/med. Facility privileges include full endoscopic spine surgery privileges at the surgical facility where procedures are performed. Malpractice history and disciplinary status are publicly searchable through the state medical board’s licensee database. The full public verification pathway for any U.S. physician’s credentials is documented at CertificationMatters.org for ABMS certifications and at state medical board websites for state-specific licensure.

The clinical outcomes side — outcomes on the specific procedures Dr. McMillan performs — is the question patients ultimately care about most. Individual surgeon outcomes are difficult to verify through public data alone; the most direct verification path is the free MRI review followed by candid discussion of specific case types and expected outcomes during the phone consultation.
