Best Doctors in America List: How Specialists Are Vetted & Top Medical Centers

The “Best Doctors in America” list is an authoritative clinical peer-reviewed database identifying the top 4% to 5% of licensed physicians across the United States. Founded in 1989 by Harvard Medical School physicians and maintained through rigorous, confidential peer surveys (now integrated within Castle Connolly and national academic medical registries), the selection process does not allow doctors to buy their way onto the roster. Instead, physicians are nominated and evaluated strictly on board certifications, surgical outcome records, clinical trial leadership, academic hospital appointments, and direct peer recommendations. This definitive guide explains how the Best Doctors in America registry works, profiles leading medical centers across key surgical and oncological specialties, and provides patients with an actionable framework for vetting top specialists.

How the “Best Doctors in America” Selection Methodology Works

Unlike commercial marketing awards or paid vanity directories, legitimate physician excellence databases employ strict, multi-stage peer-nomination algorithms combined with physician-led review boards. Castle Connolly and the legacy Best Doctors audit protocols evaluate candidates across six non-negotiable professional metrics:

• Peer Nominations: Tens of thousands of actively practicing medical doctors, clinic chiefs, and department chairs are surveyed annually with one fundamental question: “If you or a loved one had a complex medical issue in your specialty, to whom would you entrust their care?”
• ABMS Board Certification: Candidates must hold active, unblemished certification from one of the 24 member boards of the American Board of Medical Specialties (ABMS).
• Disciplinary Screenings: Comprehensive audits cross-reference all 50 state medical licensing boards, federal sanctions lists, and malpractice claims history.
• Hospital Affiliations & Faculty Rank: Preference is given to physicians holding active faculty or attending privileges at accredited university teaching hospitals and NCI-designated cancer centers.

• Dr. Craig R. Smith (Columbia University Irving Medical Center / New York-Presbyterian): Globally renowned cardiothoracic surgeon, chair of surgery, noted for landmark coronary artery bypass grafting procedures.
• Dr. Lars G. Svensson (Cleveland Clinic Heart, Vascular & Thoracic Institute): World authority on complex aortic root surgery, Marfan syndrome, and valve repair techniques.
• Dr. Michael A. Acker (Penn Medicine): Nationally acclaimed director of heart failure and ventricular assist technology.

2. Neurosurgery & Spine Innovation

Cerebrovascular and skull-base neurosurgeons handle inoperable brain tumors, vascular malformations, and microscopic spinal cord restorations:

• Dr. Robert F. Spetzler (Emeritus, Barrow Neurological Institute): Legendary pioneer in intracranial aneurysms and skull base vascular surgery.
• Dr. Alfredo Quiñones-Hinojosa (Mayo Clinic, Florida): World-renowned neurosurgical oncologist specializing in complex brain mapping and awake craniotomies.
• Dr. Henry Brem (Johns Hopkins Medicine): Department chair and innovator of biodegradable Gliadel chemotherapy wafers implanted during glioblastoma resection.

3. Medical & Surgical Oncology

Oncologists steering National Comprehensive Cancer Network (NCCN) clinical practice guidelines dictate precision targeted therapies and next-generation sequencing:

• Dr. Elizabeth Jaffee (Sidney Kimmel Comprehensive Cancer Center / Johns Hopkins): Global authority in pancreatic cancer vaccines and tumor immunology.

• Dr. James P. Allison & Dr. Padmanee Sharma (MD Anderson Cancer Center): Nobel laureate laboratory leadership defining immune checkpoint inhibition mechanisms.

4. Orthopedic Surgery & Sports Medicine

Orthopedic surgeons at specialty institutions like Hospital for Special Surgery (HSS) in New York restore joint mobility using computer-navigated robotic arthroplasty:

• Dr. Bryan T. Kelly (Hospital for Special Surgery – HSS): Surgeon-in-chief, pioneer in hip arthroscopy and elite athletic hip preservation.
• Dr. Neal S. ElAttrache (Kerlan-Jobe Orthopaedic Clinic / Cedars-Sinai): World-renowned sports medicine surgeon treating Major League Baseball, NFL, and Olympic champions.
• Dr. Todd J. Albert (HSS / Weill Cornell): Leading authority on complex cervical spine reconstruction and degenerative scoliosis.

How Patients Can Verify Doctor Credentials (Actionable Checklist)

A doctor’s bedside presence must always be corroborated by empirical public registries and hospital credentialing data. Before scheduling major surgery or an expensive consultation, verify these four independent checkpoints:

1. Check ABMS Certification: Visit CertificationMatters.org to confirm your physician holds active, subspecialty certification from an approved American Board of Medical Specialties board.
2. Verify State Licensing & Malpractice History: Search your state’s medical board database (e.g., Medical Board of California, New York State Office of Professional Medical Conduct) to inspect sanctions, reprimands, or active license suspensions.
3. Audit Procedural Volume: For complex surgeries (cardiac valve repair, joint replacement, organ transplantation), high annual procedural volume directly correlates with lower 30-day mortality and complication rates. Ask: “How many times did you perform this specific surgery in the past 12 months?”
4. Review Academic Teaching Privileges: Physicians holding appointments as Clinical Professors or Attending Physicians at university hospitals participate in peer review conferences and have access to ongoing clinical research protocols.
