PSA takes great pride in the quality of its physician members. The physicians of PSA are all board certified by the American Board of Anesthesiology. They have degrees from some of the most respected medical schools and anesthesia residency programs in the country.

PSA members have graduated from such institutions as the Johns Hopkins School of Medicine, University of California at San Francisco, The Cleveland Clinic, Emory University, The Mayo Clinic, University of Rochester, Harvard University, Columbia University, University of Florida, Bowman Gray School of Medicine of Wake Forest University, the Ochsner Clinic, and the University of Chicago. Many PSA physicians have additional areas of board certification, including critical care medicine, pain management, and family medicine.

Thirteen members have passed the National Board of Echocardiography (NBE) Examination of Special Competence in Advanced Perioperative Echocardiography and five are fully Board Certified by the NBE. Eight hold board certification in pain management by the American Board of Pain Medicine and American Board of Anesthesiology. PSA is proud to have among its members three board examiners of the American Board of Anesthesiology, highly unusual for a private practice of this size.

Finally, members of PSA have been leaders in the American Society of Anesthesiologists, the Georgia Society of Anesthesiologists, the Medical Association of Georgia, the Greater Atlanta Society of Anesthesiologists, and the medical staff of Saint Joseph's Hospital of Atlanta.
