Jennifer S. Barr, MD
Specialties: Orthopaedic Oncology, Orthopaedic, Sarcomas (Bone and Soft Tissue Cancers), Orthopaedic Joint Replacement
Gender: Female
Biography: As one of Mississippi's only fellowship trained Orthopaedic Oncologist, I have an interest of bone and soft tissue tumors both benign and malignant. I take care of patients of all ages. I also have a interest in joint reconstruction of upper and lower extremities.
My Approach to Healthcare
I believe in the team approach to safe patient care. Our chairman fostered the "we say yes" mentality 8 years ago and this has become so ingrained that I find it difficult to say "no". I strive to deliver the best care possible for each individual patient and tailor it to their specific needs.
