Mark and Mary Ellen Warner

Mark A. Warner, MD and Mary Ellen Warner, MDWe believe that foundations such as the Anesthesia Patient Safety Foundation are fundamental to the future development of anesthesiology. The APSF is especially important to us as improving perioperative patient safety is such a noble cause and has been a major goal for us during our careers. We are proud to have the opportunity to help APSF fulfill its vision that “no one shall be harmed by anesthesia care.”

Drs. Warner are anesthesiologists at the Mayo Clinic in Rochester, Minnesota. Mary Ellen has served as president of the American Society of Anesthesiologists’ Wood Library Museum and is vice-president of the Anesthesia Foundation. Mark has served as president of the American Society of Anesthesiologists, been a director of the Foundation for Anesthesia Education & Research, and is president of the APSF. Two of their sons and two of their daughters-in-law also are anesthesiologists at Mayo Clinic.


Robert K. Stoelting, MD

Robert K. Stoelting, MDThe Anesthesia Patient Safety Foundation (APSF) was established in 1985 with the vision “that no patient shall be harmed by anesthesia.” A foundation dedicated solely to advocate for anesthesia patient safety was the goal of APSF’s founding president, Ellison C. Pierce, Jr., MD. Today, APSF and anesthesiology are recognized world wide as pioneers in advocating for patient safety.

I had the privilege of following Dr. Pierce as the second president of APSF (1997-2016) and it was on the “shoulders of those early pioneers in APSF’s history” that during my presidency APSF was able to both continue and expand its role in pursuing its mission that “no patient shall be harmed by anesthesia.”


Dr. John H. and Mrs. Marsha L. Eichhorn

Dr. John H. and Mrs. Marsha L. EichhornHaving been intensely involved with the APSF since its creation in 1985, of course we are supporting its long-term survival and success, including through a contingent legacy grant as part of our estate plan.


Jeffrey and Karma Cooper

Jeffrey and Karma CooperAs a founding member of the APSF Executive Committee, I take great satisfaction in the sustained leadership and success of this organization in advancing perioperative patient safety.

What is so remarkable and has brought me great personal pleasure and joy, is the continuous, unwavering, extraordinary mutual respect, support and camaraderie of the Executive Committee. Despite almost complete replenishment of its composition more than once over the more than 30 years since the APSF’s inception, that team has sustained those qualities and continued to evolve and work effectively. The current board and leadership are a new generation; I have no doubt that they will continue that legacy of working together effectively, of innovating to meet the new challenges ahead and enjoying their working together. My expectation is that there will be a need for APSF far into the future because it will continue to evolve to meet the future needs of patient safety. Our trust in that is secure; Thus, Karma and I are confident that our pledge of support from our estate will be a worthy investment in the future.


David and Deanna Gaba

David and Deanna GabaOur two careers in healthcare were dedicated to the provision of safe patient care. David’s academic mission centered on patient safety – both on its theoretical basis and on a number of practical avenues to bring it to fruition around the world. Without APSF’s support of these efforts, and those of countless others, patient safety as a specific targetable goal would never have come to the fore. That “no one shall be harmed by anesthesia care” is a vision that we believe should continue in perpetuity.

Deanna Mann, RN, BSN, RNP, MSN is a Registered Nurse and Women’s Health Nurse Practitioner specializing in Obstetrics and Gynecology. She has worked in both hospital and community clinic settings, giving care to patients of diverse economic and cultural backgrounds. Dr. David Gaba is an anesthesiologist at Stanford School of Medicine and at VA Palo Alto Health Care System. He has served as a Director of the APSF continuously from 1990 through 2019, as well a member of its Executive Committee, and Secretary, at various times in this period. He was also a founding member of the American Society of Anesthesiologists’ Simulation Editorial Board. He was a founding board member of the Society for Simulation in Healthcare and the founding editor-in-chief of its peer-reviewed journal Simulation in Healthcare”

Dr. Ephraim S. (Rick) and Eileen Siker

Dr. Ephraim S. (Rick) and Eileen SikerRick’s interest in anesthesia began as a third year medical student at NYU when he had a brief opportunity to cross paths with Emery Rovenstine, the first of future encounters. What an honor it was when Rick was invited to give the Rovenstine Lecture in 1981. Rick’s circle of friends and influencers include too many to list, but a few names stand out: Drs. Frances Foldes, John Bonica, Pepper Jenkins, Richard Kitz, David Little, Bill Hamilton, Art Keats, Al Betcher, Don Benson, and most importantly Eileen B. Siker, his wife of more than 60 years. Rick was dedicated to patient safety and it’s noteworthy that in 1996 he was invited to present the Lewis Wright Lecture. Rick’s talk was titled; “Anesthetic Safety: an Evolution”. This would turn out to be his final opportunity to address an ASA audience.

Rick’s tenure with the APSF began in 1985 when he became the Founding Secretary. He was then appointed as the first Executive Director of the APSF, a role in which he served from 1992 – 1997.

Rick and Eileen Siker truly are an APSF legacy.
