Mammoth Orthopedic Institute

Tyler Williamson, MD, is a sports medicine fellowship-trained orthopaedic surgeon. He grew up in Minnesota and attended the University of Minnesota, where he graduated with High Distinction from his Biochemistry program. Dr. Williamson then attended New York University School of Medicine for his medical degree, after which he returned to the University of Minnesota for his orthopaedic surgery residency. He went on to complete his sports medicine fellowship in the highly active communities of Lake Tahoe and Mammoth Lakes, CA.

Dr. Williamson’s fellowship training provided experience with cutting-edge procedures, including ACL repair, the Bridge Enhanced ACL Restoration (BEAR) implant, direct anterior total hip arthroplasty, and shoulder arthroplasty using patient-specific computerized planning. Despite its sports medicine emphasis, his unique fellowship afforded continued training in knee and hip arthroplasty and fracture care. Before returning to Mammoth Lakes to join the Mammoth Orthopedic Institute, Dr. Williamson joined a private practice in Minnesota and was the first physician in the state of Minnesota to perform an ACL repair using the BEAR implant for non-research purposes.

Welcome Kat Fritz, PA-C!

We’re excited to welcome Katherine Fritz, PA-C to our team! Katherine is a Board-Certified Physician Assistant (NCCPA) with a strong background in emergency and urgent care medicine, and a passion for serving rural communities.

Katherine earned her Master’s Degree in Physician Assistant Studies from Oregon Health & Science University (OHSU) in Portland (2017–2019), where she graduated with honors and was recognized as part of the Rural Scholar Track. She completed her undergraduate studies at Grove City College in Pennsylvania (2006–2010), graduating magna cm laude with high honors in psychology, and was also named a Maryland Distinguished Scholar.

Her career began in the emergency departments of two rural Washington hospitals, followed by experience in a high-volume urgent care clinic in Portland, making her a wonderful addition to our patient care team.

Originally from rural Maryland, Katherine’s path has been shaped by both medicine and the outdoors. After college, she moved to the mountains of Colorado, where she worked as an instructor for the Colorado Outward Bound School and as an EMT.

Katherine is excited to officially call the Eastern Sierra and Mammoth home, an area she has loved for many years. When she is not working, she can usually be found rock climbing, skiing, trail running, fly fishing, or learning to sew her own clothes. She loves exploring the mountains with her partner, Maarten, and at home she is rarely without the company of her three cats.

Please join us in giving Katherine a warm welcome. We’re so happy to have her here!
