Meet Dr. Marc Greenberg
Dr. Marc Greenberg is a fellowship-trained orthopedic spine surgeon focused on minimally invasive, robotic, endoscopic, and motion-preserving care. His training pathway runs through three of the nation's premier institutions—Mayo Clinic (MD), Johns Hopkins (Orthopedic Surgery Residency), and Brown University (Spine Fellowship)—a pedigree that underpins his precision-first, recovery-focused approach.
Surgical Precision, Minimally Invasive When Appropriate
Dr. Greenberg's promise is simple: the least invasive option that truly solves the problem. When surgery is appropriate, he prioritizes motion-preserving solutions (e.g., cervical disc replacement) and muscle-sparing techniques (robotic navigation, endoscopic decompression) to reduce pain, shorten hospital stays, and speed a confident return to work, family, and sport.
Philosophy
Dr. Greenberg's promise is simple: the least invasive option that truly solves the problem. When surgery is appropriate, he prioritizes motion-preserving solutions (e.g., cervical disc replacement) and muscle-sparing techniques (robotic navigation, endoscopic decompression) to reduce pain, shorten hospital stays, and speed a confident return to work, family, and sport.
Clear Diagnosis, Patient-First Planning
Every treatment decision starts with thorough review of MRI or CT imaging to identify the structural cause of symptoms. Dr. Greenberg believes in conservative care first when appropriate, with surgery reserved for cases where non-surgical treatment has not provided adequate relief or when progressive neurological symptoms are present.
Patients receive clear explanations of all appropriate options, realistic expectations about outcomes and recovery, and support in making the decision that aligns with their goals and values.
Clinical Philosophy
- Imaging-based diagnosis: Every treatment decision starts with thorough review of MRI or CT imaging to identify the structural cause of symptoms.
- Conservative-first when appropriate: Most spine conditions improve with non-surgical care. Surgery is reserved for cases where conservative treatment has not provided adequate relief or when progressive neurological symptoms are present.
- Minimally invasive when appropriate; fusion when necessary: Motion-preserving and minimally invasive techniques are prioritized when imaging and symptoms support their use. However, conditions involving instability or deformity may require fusion for optimal outcomes.
- Shared decision-making: Patients receive clear explanations of all appropriate options, realistic expectations about outcomes and recovery, and support in making the decision that aligns with their goals and values.
Areas Served
Dr. Greenberg is establishing his practice in Fort Wayne, Indiana, serving patients throughout northeast Indiana and northwest Ohio. Patients commonly travel from surrounding communities including Warsaw, Auburn, Huntington, Columbia City, Angola, Kendallville, and Bryan, OH for fellowship-trained spine surgery expertise.
Clinical Interests
Cervical disc replacement (ADR), endoscopic cervical/lumbar decompression, MIS TLIF/PLIF, ACDF/cervical foraminotomy, adult deformity, revision surgery, kyphoplasty, and SI joint fusion.
Recognition & Leadership
At Johns Hopkins, Dr. Greenberg served as Chief Resident Director and Chief of Education and was recognized as Emergency Department Consult Resident of the Year (2022–2023) and House Staff Resident of the Month.
Research & Teaching
Dr. Greenberg has contributed peer-reviewed work and book chapters spanning spine outcomes, cost-utility in ACDF, perioperative optimization, and MRI fundamentals, with presentations at national meetings including AAOS and AOFAS. Publications include Spine, JBJS, Journal of Arthroplasty, Seminars in Spine Surgery, and textbook chapters.
Outside the OR
Marc is married to his wife Maayan; they share life with a Golden Retriever puppy. He grew up around horses, still loves to ride, and brings that same calm, steady focus to caring for patients.
