Total Joint Replacement of the Hip & Knee

"I have enjoyed being part of the growth and development of Orthopedic Fracture Clinic, Orthopedic Healthcare Northwest, and now the Slocum Center over the past 45 years. Doctors Slocum, Larson, and James were the orthopedists who brought me to this medical community, and the commitment to provide the very best specialty orthopedic care has been very fulfilling for me."

Dr. Dennis Collis is available to see patients at our Eugene location.
