Message from Dr. Mora
"I hope to create a close patient-doctor relationship based on trust and mutual respect. I believe my patients’ medical treatment begins with their complete understanding of their condition, and I promise to do my very best to understand the cause of your pain and then provide a treatment approach that is tailored to meet your specific needs.
I believe that my success in diagnosing and treating orthopedic problems was borne out of my own personal traumatic injury to my legs. While living in Peru, I was struck by a commuter bus, severely injuring my legs and forever changing my life. I have experienced many of the same surgeries that I now perform on my own patients — and I believe this experience has allowed me to be more in tune with my patients’ concerns, symptoms and experiences.
My family heritage is Peruvian and I speak fluent Spanish."
