Our History

Physician Specialists in Anesthesia was founded in 1979 by Dr. Stan Mogelnicki and Dr. Donn Chambers when Saint Joseph's Hospital of Atlanta moved from its historic site in downtown Atlanta to the new location in suburban northern Atlanta. Drs. Mogelnicki and Chambers assembled a small group of talented cardiovascular anesthesiologists which became the nucleus of the present-day group.

PSA has enjoyed a steady increase in the size and diversity of its physician staff. Owing to its primary practice location at Emory Saint Joseph's Hospital, the group maintains as its primary areas of expertise the fields of cardiovascular and thoracic anesthesia with emphasis on invasive hemodynamic monitoring and perioperative echocardiography. Other areas of special expertise include critical care medicine, regional anesthesia, acute pain management, and anesthesia for specialty surgery (general, orthopaedic, plastic surgery, surgical oncology, otolaryngology, neurosurgery, and geriatric).

We have broadened our expertise over the past four decades to include outpatient anesthesia and the management of ambulatory surgery center anesthesia departments. Through the use of optimum staffing models, continuous quality improvement, best practices, and a strong cost containment culture, PSA has helped organizations provide the highest quality ambulatory surgical product, while being fiscally responsible.

A Message From Our Director

Welcome to Physician Specialists in Anesthesia, P.C. ("PSA")! Whether you are a patient, prospective team member, prospective surgical or facility partner, or a community member, we are delighted that you are here. Since its founding in 1980, we have been committed to maintaining a culture of service, clinical excellence, and corporate integrity, and we have become a leading provider of adult anesthesiology services to some of the finest healthcare organizations in the Southeast. This success stems not only from the high quality of our physicians, exceptional advanced care providers, and dedicated support staff but also from the remarkable excellence of our partner organizations. PSA was born to serve the anesthesiology and perioperative services needs of Saint Joseph's Hospital of Atlanta upon its historic 1980 move to the northern perimeter of Atlanta. The synergy between Saint Joseph's and PSA in the 1980s and 1990s helped both organizations earn sterling reputations from Atlanta's patients and doctors. These reputations soared higher upon Saint Joseph's joining Emory Healthcare, one of the Southeast's largest and most respected academic and community health systems. As a result, Emory Saint Joseph's Hospital is now a critical piece of the Emory Healthcare system, and PSA couldn't be more proud of its contributions there and of its members' ability to contribute to the success of the entire Emory Healthcare system.

PSA's other community partners are no less prestigious. For example, PSA has been the exclusive partner of Resurgens Orthopaedics and United Surgical Partners International (USPI, now a division of Tenet Healthcare) since the early 1990s at its flagship four-operating room orthopaedic surgery center on the campus of Emory Saint Joseph's Hospital— a center of technical innovation in outpatient total joint reconstruction, sports medicine, spine care, and the full spectrum of orthopaedic care. Most recently, PSA is pleased to partner with Northwest Ear Nose and Throat, a premier ENT surgical practice serving metro Atlanta's rapidly growing northwest and Buckhead areas.

PSA would be nothing without its most valuable assets, its people. PSA team members serve in varied clinical and advisory roles within our health system and facilities, including advanced cardiothoracic surgery and cardiology service lines, critical care medicine, acute pain medicine, and the general anesthetic care of adults and children. In addition, our team members have served in honored leadership roles in every significant anesthesiology and anesthesia organization in the United States, including the American Society of Anesthesiologists and the American Board of Anesthesiology, among many others.

As an organization, PSA's mission is to serve the greater Atlanta and Georgia communities by delivering compassionate, high-quality anesthesia care that promotes healing and reduces human suffering. That mission links us inextricably with our principal hospital partner, Atlanta's first faith-based and longest-serving hospital, whose mission is the same today as it was over 140 years ago— to provide compassionate care, especially to those in need. As such, the needs of our patients and our community come before all else, and we believe in community over competition for the betterment of society, our community, and humanity.

We thank you for the opportunity to serve you. Please let us hear from you.

PSA Support Of The Mercy Care Foundation
For the 31st year running, PSA sponsored the Mercy Care Foundation at its annual Wings of Mercy Ball. This most recent year’s fundraising efforts were in support of the Mercy Care’s dental clinic, which provides preventative and restorative oral and dental services to patients in the greater metro Atlanta area.

In its Thanksgiving 2020 campaign, PSA raised $29,500 for Mercy Care’s Street Medicine program which provides mobile primary care and behavioral health services to Atlanta’s most critically underserved homeless communities. In all, PSA has contributed over half a million dollars to Mercy Care over the past three decades, and is proud to designate Mercy Care as the official charity organization of the group. More information about Mercy Care can be found at www.mercyatlanta.org

Anesthetist Jimmy Lunsford (PA-C, CAA) Selected To Serve In The GA-3 Disaster Medical Assistance Team 
PSA Associate Chief Anesthetist Jimmy Lunsford has been selected to serve as a Physician Assistant with the GA-3 DMAT (Disaster Medical Assistance Team). Involvement with DMAT is something Jimmy has been working towards since 2005, after seeing first-hand the devastating effects of Hurricane Katrina and volunteering in Slidel and New Orleans with interior demolition of flood ravaged homes and a church. "During disasters and emergencies – and even during large-scale national security events - the need for medical care can quickly overwhelm the system. NDMS Disaster Medical Assistance Teams (DMATs) may be deployed to get people the medical care they need when seconds count." More  information can be found at: www.phe.gov/Preparedness/responders/ndms/ndms-teams/Pages/dmat.aspx

Jimmy is currently the only PA in the Emory Healthcare system serving on a Georgia DMAT. PSA is very proud of Jimmy’s amazing work, serving not only our patients, but the larger Georgia community.

Dr. Steven Sween Serves as President of the American Society of Anesthesiologists Charitable Foundation
American Society of Anesthesiologists (ASA) members have a long history of contributing to those in need. Countless members volunteer their professional skills in the far corners of the world. In the midst of unspeakable disaster, anesthesiologists respond generously with time and money to support those in need.

For decades, the ASA has supported anesthesia education in remote facilities in Africa through the Overseas Teaching Program. When Hurricane Katrina disrupted medical care and anesthesia education here at home, ASA members contributed to the support of anesthesia trainees urgently relocated to continue their education.

The earthquake that devastated Haiti in 2010 produced an outpouring of volunteer anesthesiologists participating in the disaster relief efforts there. Later that year, ASA members began a partnership with Hope for the Warriors to raise funds to aid military families coping with casualties of war. American anesthesiologists have contributed hundreds of pulse oximeters to the developing world through the Lifebox initiative and will lead the effort to introduce oximetry and safe surgery practices in Central America.

As President of the ASA Charitable Foundation, Dr Sween is responsible for oversight and coordination of these worthy relief and philanthropic efforts. More information about the ASA Charitable Foundation can be found at www.asacharity.org
