Mark Alexander, MD

Musculoskeletal Primary Care/Acute Injury

Since I decided to become a physician, sports medicine is always what I have wanted to do. I try to take something from each of my experiences as a patient, athlete and a life long learner in medical field. I strive to get people back to their activities as quickly as possible. When not in the clinic or on the sideline, I enjoy spending time with my wife and three children.

Elizabeth Arendt, MD

Orthopaedic Surgery/Sports Medicine Fellowship

For leisure activities, I enjoy cycling, squash, cross-country skiing and golf. I also enjoy reading fiction, as well as orthopaedics! I am married with two nearly grown children.

Don Asmussen, MD

Musculoskeletal Primary Care

I enjoy the diagnostic challenges associated with spine medicine. I am active with my family with boating, skiing and garden work.

Heather Bergeson, MD, CAQ

Sports Medicine & Pediatrics

As a sports medicine physician, I enjoy caring for musculoskeletal issues in patients of all ages. As an experienced pediatrician in our community, I have a special interest in the young athlete and strive to promote health and physical fitness at an early age. My philosophy has always been "exercise is medicine" and my goal is to keep my patients active and healthy throughout their lives. Clinical interests include osteochondritis dissecans, spondylolysis, growth plate fractures, overuse injuries, and female athletes. My favorite activities are Nordic and alpine skiing, yoga, running, and cycling - especially when my husband and two kids are with me.

Deb Bohn, MD

Orthopaedic Surgery/Hand Fellowship

I enjoy taking care of hand and arm problems in patients of all ages. It is very rewarding to help people return to their important activities, whether it be buttoning a shirt or swinging a golf club. I have a special interest in fractures and children's upper extremity problems. When I'm not taking care of patients, I enjoy cooking, gardening and raising my beautiful children.

Joel Boyd, MD

Orthopaedic Surgery/Sports Medicine Fellowship

I enjoy spending time with family, traveling, playing golf, watching movies and listening to music in my free time.

Jonathan Braman, MD

Orthopaedic Surgery/Shoulder Fellowship

Every day, I have the chance to meet patients who are in pain and have problems with their shoulders. By focusing on only one joint, I can help patients understand their surgical and nonsurgical choices. Whether a patient has a broken shoulder, a dislocating shoulder, an arthritic shoulder or a torn rotator cuff, I enjoy the opportunity to work with them and determine what treatment best fits their needs.

Stephen England, MD, MPH

Pediatric Orthopaedic Surgeon

As a pediatric orthopaedist, I enjoy working with families to manage and treat all aspects of orthopaedics in young children and adolescents. Children are not simply small adults and their unique injuries and conditions require great attention and ongoing care.

Gary Fetzer, MD

Orthopaedic Surgery/Sports Medicine Fellowship

Dr. Fetzer is an Adjunct Assistant Professor in the Department of Orthopaedic Surgery and fellowship-trained sports medicine surgeon. His clinical interests include sports medicine and athletic injuries, including knee ligament reconstruction, articular cartilage and meniscal surgery, arthroscopic shoulder instability and rotator cuff repairs, hamstring injuries, and sports-related ankle injuries.

David Fischer, MD

Orthopaedic Surgery

My practice is focused on the diagnosis and treatment of knee injuries and conditions, from the pediatric population to those encountered in the athlete to later stages of arthritis and total knee replacement. I enjoy woodworking, cooking, baking, fishing and hunting waterfowl. My wife and I have enjoyed collecting American Folk Art over the years. We and our two adult children live in the Twin Cities and continue to enjoy many family events around sports and regular family dinners.
