Paul M. Guidera, MD, FACS

Dr. Guidera is a Board certified Fellowship trained Hand and Upper Extremity specialist. He is a graduate of the University of Maryland Medical School, completed residency training in general surgery and plastic & reconstructive surgery as well as an orthopedic hand surgery fellowship. He began his surgical career here in Arizona in 1995.

While in college, he worked as a hospital orderly and then as a surgical scrub tech in the operating room on the night shift while attending classes during the day. This early exposure to patient care as well as to incredible nurses and doctors helped to focus his interest in medicine.

Dr. Guidera worked continuously during college and medical school to pay for his education. In addition to working in the hospital, he held jobs as a construction laborer, a landscape worker and a farm laborer. He has never forgotten what it takes to perform manual labor… insight that to this day contributes to his understanding of just how consequential hand injuries are to many people.

At age 20, he left college and spent a year in rural India as a volunteer. During his time there, he was part of a first responder team dispatched to the southern coast following a tragic tidal wave that took more than 100,000 lives and destroyed entire coastal towns, villages and farming communities. He worked alongside Indian physicians and nurses in an austere environment for four months. He spent the rest of that year working at a leprosy hospital with a Swiss plastic surgeon, restoring hand function and treating other ravages of that disease.

He returned home and finished college with a degree in psychology. He then worked as a child abuse investigator for the City of Baltimore before applying to medical school.

Dr. Guidera was fortunate to have early exposure to the Jesuits. Their educational and moral mission is summarized in the motto, “a man for others”. This is a commitment to a life spent helping others and is a philosophy woven continuously through rigorous academic experience and an emphasis on self-reflection, logical thinking and the construction of a strong moral compass. It is a commitment that led to his decision to become a physician.

During four years of medical school and eight rigorous years of residencies and fellowships, Dr. Guidera sought meticulous diagnostic and technical training experiences. This led to extensive exposure to hand surgery, the foundations of which are by nature complex, nuanced and exacting. This led to a fellowship with Dr. H. Kirk Watson, one of the best known hand surgeons in the world.
