Berry and Dr. Antonio Arazoza. Dr. Berry has practiced at Methodist Dallas
Medical Center since 1971. The group, now known as Methodist Orthopaedic
Surgical Associates (MOSA), is comprised of five orthopaedic surgeons
and one podiatrist, to have a full spectrum of musculoskeletal care. Dr.
Miguel A. Hernandez III joined the group in 1997 and Dr. Ray F. Aronowitz

All five staff orthopaedic surgeons are Board Certified or Board Eligible,

their knowledge in the field by passing written and oral examinations
given by eminent orthopaedists around the country. Dr. Nathanson has over
20 years of podiatric experience in the military.
