J. Cairn Marrale, NP, PhD (retired)

Cairn was born and raised in a small Western New York village, graduated from Attica High School and relocated to Buffalo to attend Nursing School. After graduating from nursing school, Cairn worked for the next 10 years in the emergency room of what was Edward J. Meyer Memorial Hospital. In the meantime, she married and left that position when her son was born. She and her husband adopted a daughter and after the children were in school she returned to her nursing career and attended UB where she earned her BSN, MSN and subsequently a PhD in Medical Sociology. Cairn worked as a Nurse Practitioner in a Primary Care office until she was recruited to teach in the Masters NP Program at UB. During that time, she wrote a grant for an Occupational Health Nurse Practitioner Program which was funded and students were enrolled for the next 3 years. Cairn decided not to renew the grant and instead took time off to complete her PhD. Shortly thereafter she was recruited to work at Buffalo Rheumatology where she spent the next 22 years.

Cairn prides herself in being a patient advocate and being able to assist those who are in need of physical, emotional and spiritual help. She particularly enjoys people, especially children, gardening and playing her saxophone in the Worship Team at her church.

Cairn retired in June 2018 to pursue her many other interests and charitable endeavors. We begrudging allowed this!

She will be greatly missed but her presence lives on at Rheumatology Wellness Care.
