John M. Norian, MD, FACOG

About

John Norian built a practice around the questions a standard IVF consult tends to skip: what you eat, how you live, and how those things change the quality of the eggs and sperm being retrieved. He is a board-certified reproductive endocrinologist at HRC Fertility, splitting time between the Pasadena and Rancho Cucamonga clinics, and he pairs that lifestyle focus with an emphasis on the patients other programs discourage early — low responders and those with poor ovarian reserve.

His training path is a long one and deliberately multidisciplinary: a history and pre-medical degree at UC Berkeley, a master’s at Boston University School of Medicine, and his medical degree at Ireland’s Royal College of Surgeons, where he graduated with honors in the top of his class. He completed OB/GYN residency at the Albert Einstein College of Medicine and Montefiore Medical Center in New York, then an REI fellowship at the National Institutes of Health, and he has held clinical teaching appointments at multiple California medical schools.

He is a frequent author of peer-reviewed articles and co-author of books on reproductive biology, and he presents at national and international meetings. He has been named to Los Angeles Magazine and Southern California Super Doctors from 2017 to 2025, and his multilingual team supports care in English, Spanish and Chinese.
