Justin Roberts, MD

Orthopedic Surgery, Knee Orthopedic Surgery, Foot and Ankle Orthopedic Surgery

Physician, TOCA at Banner Health
I promote a relaxed atmosphere where open and honest communication is encouraged. Patient education is a critical part of my practice. I will take the time to explain the diagnosis and treatment options, emphasizing non-operative measures prior to surgery whenever possible. I understand that orthopedic problems can be very disabling and recovery can be extensive, while also recognizing that optimal function requires precise interaction between all of the joints of the lower extremity. I am dedicated to finding the root of the problem and working to get patients back to the lifestyle they desire.

Samuel Harmsen, MD

Shoulder Orthopedic Surgery, Shoulder and Elbow Orthopedic Surgery, Orthopedic Surgery

Physician, TOCA at Banner Health
I like to create a professional but relaxed clinical atmosphere where everyone feels comfortable and able to ask questions freely. My approach is centered around your individual concerns and goals. Together, we will come to a shared decision on an evidence-based treatment plan that helps you get back to your life, work and recreational activities. I strongly believe that clear communication, patient education, and patient participation are vital to the success of our treatment plan, whether conservative or surgical. My goal is for you to leave each visit confident, encouraged and understood. I look forward to meeting you and helping you get back on track.
