I am sorry to hear this sad news. Peter Callen was a remarkable man and his work will surely continue to guide generations of students and doctors. His wife, Karen Callen, MD, is also a wonderful person, and I send my condolences to her and their family.

Peter was one of my most respected mentors. During my time at UCSF as an ultrasound student he spent time helping me navigate through my training with patience, kindness and always with laughter. He was someone I respected and admired and will never forget how he always made time to help... no matter what the struggle. He will always be remembered and his kindness will never be forgotten. My thoughts and prayers go to his wife Karen and his children. May His Memory Be Eternal
