About us

Ask our alumni why they chose an orthopaedic surgery residency at Geisinger and they’ll tell you there simply isn’t a better place to commit yourself to learning. We’ve carefully built our residency around education, not work, to create an experience unlike any other in the country — and our residents’ exceptional Orthopaedic In-Training Examination scores showcase the benefits of our approach. 

Since 1960, our innovative preceptorship training model has allowed our residents to develop and strengthen their skills and autonomy. Here, you’ll have high case volumes of patients who intentionally seek our groundbreaking care. You’ll enjoy protected time so you can focus on deep learning. You’ll discover mentors who truly want you to succeed. And you’ll develop friendships and contacts that will enrich your personal and professional lives for years to come. 

A Geisinger Orthopaedic Surgery residency isn’t just out of the ordinary — it’s extraordinary. Join us and discover what you can do with the camaraderie and support of a team that cares.

Welcome from the program director

Welcome to Geisinger Orthopaedics! We’re excited to have you visit, even if only virtually. On the following pages, we hope to provide you with enough information to see why our educational experience and unique learning environment are second to none.

Located in rural central Pennsylvania, our program matches four residents per year. With over 30 faculty members representing all orthopaedic surgical subspecialties, the opportunities for learning are unparalleled. While other programs around the country struggle to maintain case volumes and protect educational time, we continue to excel in producing first-rate surgeons and clinicians.

Our curriculum centers around a daily commitment to didactics and a unique mentorship model that has been in place for over 30 years. The majority of our three-month rotations pair residents one-on-one with a mentor attending. These preceptorships allow residents rapid autonomy and a depth of education not afforded with a traditional service model.

A departmental commitment to residents as learners, not as workers, is reflected in our extensive use of physician extenders to support each attending physician. Junior residents function independently, gaining early clinical and operative experience.

On a personal note, I am a product of this program. My decision to return after fellowship was an easy one: The opportunity to teach and continue Geisinger’s legacy of producing outstanding surgeons was enough for me.

Program overview

Curriculum and didactics

The core of Geisinger’s Orthopaedic Residency Program is our unique preceptorship style approach to surgical training: As a resident, you will be paired one-on-one with attendings for three-month blocks. Since its inception in 1960, preceptorship teaching has fostered close supervision and graduated autonomy. This model allows the teaching staff to better evaluate and improve upon your ability, encouraging earlier autonomy in both the clinic and the operating room.

This level of teaching has successfully trained well-rounded, confident, capable surgeons with the ability and skill set to practice general orthopaedic surgery or to apply for highly competitive fellowships.


Our program has a long tradition of exceptional performance on the annual orthopaedic in-training examination. For the past 15 years, our residency program has consistently scored above the 95th percentile on our performance on the Orthopaedic In-Training Examination (OITE), and most recently the 99th percentile! We take pride in our curriculum and prepare you to excel in the fundamentals of orthopaedic knowledge and in the operating room.
Curriculum program structure


We emphasize early exposure to orthopaedics. As a PGY1, you’ll rotate within the orthopaedic department for six months, the maximum time allowed by the ACGME. This comprises a total of four-and-a-half years of pure orthopaedic rotations. The first six months of intern year are non-orthopaedic rotations, which include:

  • Trauma surgery
  • Plastic surgery
  • Emergency medicine
  • Radiology
  • Anesthesiology
  • Vascular surgery

The second half of your intern year is dedicated to junior orthopaedic rotations. These usually include trauma, upper extremity, spine, pediatrics and adult reconstruction.

PGY 2-5

After intern year, residents rotate throughout all the orthopaedic subspecialties. You are integral team members of each subspecialty service and serve as a key part of patient care. 

From PGY2 year through graduation, you’ll be paired with an attending on service for three-month blocks. Your schedule mimics that of your attending partner — typically two operative days and two clinic days per week. This model allows you to become proficient with preoperative evaluation and planning, postoperative care, assessment of outcomes and participate in continuity of care. In the OR, progressive surgical autonomy and independence are given to those residents who demonstrate they are capable of operating in a safe and efficient manner.

Clinical services

  • Adult reconstruction
  • Foot and ankle
  • General orthopaedics
  • Hand, wrist and microvascular
  • MSK oncology
  • Pediatric orthopaedics
  • Shoulder and elbow
  • Spine
  • Sports medicine & arthroscopy
  • Trauma

PGY 2 – PGY 5 sample rotation schedule

  • Monday: GMC clinic
  • Tuesday: GMC operating room
  • Wednesday: Outpatient clinic
  • Thursday: Outpatient surgery center/operating room
  • Friday: Half-day clinic, half-day research
Operative experience

We strongly believe that early hands-on supervised experience in the operating room is a driving factor to the success of future surgeons. On average, Geisinger orthopaedic residents log approximately 2,500 to 3,000 operative procedures by the end of residency.

You will pair one on one with attendings for three-month blocks, progressively working toward total patient care, surgical skills and fracture management. This allows us to produce compassionate, knowledgeable and technically competent orthopaedic surgeons.

Call schedule

From PGY2 (October – June) through PGY5, you’ll take orthopaedic call from home. Call covers all aspects of adult and pediatric trauma and care for all orthopaedic surgery inpatients. When not on call, you are free from clinical responsibilities. We believe the night float system employed by most programs constitutes a significant loss of educational time and a disengagement from clinical learning.

During the first three months as a PGY2 (July – September) you’ll take call with an upper-level backup. This allows you, as a junior resident, to learn the essentials of independent emergency orthopaedic care in preparation for taking call individually.

Starting in October of PGY2 year, solo call begins. PGY2 – PGY5 residents share call equally.

  • One attending, one resident
  • Monday – Thursday: 1/9 on average
  • Weekend: 1/4 on average

Daily protected teaching time is a mainstay of our program. Our dedication to daily education has led to exceptional OITE scores, ranging from the 96th to 100th percentiles for the past five years. We also have the added benefit of a devoted orthopaedic skills lab, allowing for both sawbones and anatomic procedural development.

  • Senior resident directed review of the current Orthopaedic Knowledge Update: Tuesday – Thursday, 6:30 – 7 a.m.
  • Daily protected didactic conference for all orthopaedic residents: 7 – 8 a.m.
  • Monday morning trauma conference
  • Monthly Morbidity, Mortality and Management (M&M&M) conference (a Geisinger-only conference)
  • Anatomic specimen dissections; skills lab
  • •  Prepared by PGY1 residents as part of the fall curriculum and led by subspecialty staff, this conference includes extensile dissections to review relevant anatomy and describe the surgical approaches that are performed.
  • Orthopaedic Knowledge Update (OKU) review
  • Bioskills lab, alternate Fridays in the skills lab
  • •  Arthroscopy towers
    •  Sawbones
    •  Anatomic specimen
  • Journal club
  • •  The Journal of Bone & Joint Surgery review
    •  Journal of the AAOS review
    •  Multiple sub-specialty reviews

We encourage our residents to take part in yearly national conferences to enhance knowledge, improve skills and be exposed to innovation withing our specialty. These courses are supported by the residency outside of each residents allocated annual CME benefits.
