Dr . O'Leary was one of my favorite mentors when i was in the Heme-Onc program at GW. he taught me much in hematology but especially in Coagulation. I still use much of what the taught me when I teach PAs/ thanks Dennis

Dennis O'Leary was a shining halo in the O'Leary family when I was at Shawnee Mission High School. We were not friends, but I was very close to his younger brother Theodore Morgan O'Leary, who we all called "Morgan." Morgan always spoke admirably of his big brother and felt sometimes shadowed by all his accomplishments. Their family was intellectually superior to most of the parental models I knew at the time,, and I, and my friends, held them in high esteem. I especially remember their...

I was honored to work for Dennis at the Joint Commission for 10 years. He was an extraordinary and visionary leader, always approachable, and seemed to remember first names of everyone on staff. I loved his dry humor, incredible passion for patient safety, even his wholehearted support of the employee choir Holiday performance. I myself have experienced positive outcomes because of all his work to bring performance measurement and patient safety to the forefront of care. We were blessed to...

Hi Margaret. It's Mike Frumkin. I just saw Dennis' obituary in the NYT today. Very sorry to hear. I remember you fondly, and hope that you are doing well. You were one of my favorite colleagues. It's been a while since we were at NWCH. Plenty of years have passed; so saddened for your loss. Wishing you well.

I am sorry for the loss of Dr. O'Leary who offered his respect and care for those receiving health care. He dedicated his career life to learning and teaching about health care system improvement in keeping patients safe. I am grateful and feel privileged to have been on his team and to have been part of the beginning of the patient safety national and international focus. My condolences to his family.

DSO as we fondly referred to him, was the best person I ever worked for. He put his faith in me to do a difficult job and helped me to thrive professionally. He was open to providing competent women with work opportunities we might otherwise not have had. He was brilliant and made changes in our Healthcare system that were extremely difficult to pull off, but that helped improve US patient care and safety. He supported our efforts to spread the use of standards of care to other countries. I...

I am saddened to learn of Dr. O'Leary's passing. I was fortunate to have worked at The Joint Commission under his leadership. I was inspired by his willingness to fight for patient safety. It was an honor to me when called to meet with him, even when the meeting was prompted by some sort of trouble I may have caused. He was tough, but encouraging. Praise from him had to be well deserved. I became a better professional through my experience working with him and the team he created. He...

Sending love to you all at this sad time of loss. Dennis meant so much to so many and led a new way to think about what quality means in health care. His book detailing his amazing life brought so many memories and so much joy. He made a great difference in this world with his wonderful life.
