About the Physician

Dr. Peter Murphy is a medical school graduate from the University of Dublin, Ireland. He completed his residency and fellowship in Pulmonary and Critical Care Medicine in Upstate New York, and following was an assistant professor of medicine at the State University of New York, Buffalo. Primarily because of the inclement weather in upstate New York, he moved to California in 1979 in search of warmer climate. Over the past 30+ years in Sacramento, he has practiced primarily in pulmonary and critical care medicine, with the majority of the time spent in the hospital. Dr. Murphy is a former Chief of Staff at Mercy San Juan Medical Center and has been the Medical Director of the ICU there since 2000. Although his professional interests have a wide range, Dr. Murphy’s professional passions are caring for hospitalized patients in the areas of critical care medicine, asthma, and the diagnosis and treatment of lung cancer.


Dr. Murphy joined PMA in 1977. He has a large outpatient practice with a special interest in asthma, interstitial lung disease and addressing the diagnostic and therapeutic dilemma of shortness of breath syndromes. Additionally, he has a substantial practice in the medical-legal field both in occupational pulmonary evaluation as well as medical expert review and testimony. He also appreciates the benefits of combining work and leisure, and has worked several weeks a year as the physician on cruise ships.

Dr. Murphy is also an enthusiastic cyclist, cycling about 7500 miles per year. He loves to ride his bike in the foothills with his friends, enjoying the fabulous scenery. He has taken multiple cycling vacations in Europe as well as Canada and the Western United States and has cycled on many occasions from Sacramento to Yosemite via Tahoe and Mono Lake. In his spare time, Dr. Murphy also enjoys golfing and snow skiing, primarily in the Tahoe Area as well as other resorts in the Western United States and Canada.


He is active in the community, having served as president of the school board at Our Lady of Assumption Catholic School as well as a board member of the Hospice organization.


My wife Aileen, who is also Irish, and I have three children who are working in the area in insurance, nursing and finance.


I feel honored to be able to partner with my patients and colleagues to address the challenging health care issues that I see on a daily basis. There is no greater joy than to be able to make a positive impact in another person’s life at a critical time for that individual. I have experienced this on many occasions in my professional career as well as seeing this close up within my own family. I very much agree with the American Lung Association’s slogan, When you can’t breathe, nothing else matters.


There is nothing like a health challenge to help focus on what are the important things in life.


Dr. Murphy’s sincere wish for his patients is that they benefit from, and enjoy their interaction with PMA.
