For Dan Streja, M.D., being a physician is literally all in the family. “Both my parents, my grandfather and aunt were doctors,” he says. “At 5 years old, I was giving shots to pillows!”

With over 40 years in practice, Dr. Streja has had a long and distinguished career as a Board-certified internal medicine physician with a specialization in endocrinology. He attended medical school at Carol Davila School of Medicine in Bucharest, Romania, and the University of Manitoba and the University of Toronto, Canada. He is a Fellow of the Royal College of Physicians of Canada and is certified by the American Board of Internal Medicine in endocrinology, diabetes, & metabolism.

Why internal medicine? “I was attracted to internal medicine by the intense interaction with people, and to endocrinology in particular for the high intellectual requirements necessary and the low need for invasive procedures. Initially, I wanted to be a surgeon like my father but after I assisted him during a procedure, he said ‘absolutely not!’”

Fortunately, Dr. Streja found his calling. “I love people and I am happiest when I know I helped them,” he asserts. No one would guess by his unassuming nature that Dr. Streja has given hundreds of lectures to his colleagues across the United States and around the world, and has written 64 peer-reviewed articles and four chapters in books in his clinical specialty. He has participated in or led 150 clinical trials and currently serves as a Clinical Professor at the David Geffen School of Medicine at the University of California, Los Angeles. He speaks, English, French, Spanish and Romanian.

With two daughters who followed him into health care, Dr. Streja is equally proud of his family. One has a Ph.D. in public health and works for the National Institutes of Health, the other is a professor of Epidemiology at the University of California, Irvine. He and his wife celebrated their 50th wedding anniversary in June 2021 and have five grandchildren whom they adore.

In his spare time, Dr. Streja watches chess and bridge online. “I don’t have time to play,” he says. An avid world traveler, he has visited 42 of the 50 U.S. states, all the countries of Europe, Mexico, Costa Rica, Brazil, Argentina, Chile, Turkey, Lebanon, Israel. Malaysia, Cambodia, Vietnam, Thailand, Taiwan and Japan. “Now, I am only visiting my grandchildren in Virginia!” he says.
