O. Brant Nikolaus is a fellowship-trained and board eligible orthopaedic surgeon practicing in Salt Lake City, Utah. Dr. Nikolaus completed his undergraduate studies at the University of Utah before attending the world-renowned Mayo Clinic College of Medicine in Rochester, Minnesota for both medical school and orthopaedic surgery residency. He later completed a fellowship in advanced hip and knee reconstruction at OrthoCarolina Hip and Knee Center in Charlotte, North Carolina.

Dr. Nikolaus specializes in hip and knee reconstruction, including primary hip and knee replacement, partial knee replacement and complex revision hip and knee reconstruction. For Dr. Nikolaus, the patient always comes first. This philosophy of care was engraved in him during his time with the Mayo Clinic and is evident as he passionately identifies and fixes the orthopaedic challenges facing each patient.

Dr. Nikolaus calls both Arizona and Utah “home” as he grew up in rural Arizona and moved to Utah in high school. The 4th of 8 children, he was the first in his family to graduate from college. Dr. Nikolaus is married to his high school sweetheart and the proud father of three daughters and one son. He is an accomplished singer and also enjoys participating in Spartan Races, training at the gym, watching and playing different sports and enjoying the outdoors with his family.
