My Team
Dr. Hatzidakis' Team
For almost two decades, I have been a proud physician partner at Western Orthopaedics, the oldest private orthopedic group in Denver, Colorado. As one of the last independent orthopedic practices remaining in Colorado, we maintain the freedom to practice medicine with unaltered ethical standards and can always do what’s best for each of our patients.
We see over 3000 patients in our clinic each year, and because of the high demand for our exceptional shoulder care, we have created a team of highly specialized providers. Each provider is an expert in treating shoulder, elbow and athletic injuries and being seen by a team creates the best evaluation and care.
Fellowship
Teaching is a passion
We’re very passionate providing extraordinary shoulder care, collecting the outcomes of our patients and publishing research on our outcomes. We are also passionate about advancing the care of shoulders for future patients by teaching other orthopedic surgeons and sharing our knowledge. We do this through our Western Orthopaedics and Rose Medical Center Shoulder and Elbow Fellowship which is a one-year training for an orthopedic surgeon looking to special specialize in shoulder care.
