Full articleHoward Krein is an American otolaryngologist and facial plastic and reconstructive surgeon practicing at Thomas Jefferson University Hospital in Philadelphia, Pennsylvania. A native of New Jersey, he earned his MD and PhD from Sidney Kimmel Medical College at Thomas Jefferson University, holds dual board certifications in otolaryngology-head and neck surgery and facial plastic and reconstructive surgery, and has contributed to over 79 peer-reviewed publications in his field. Krein married Ashley Biden, daughter of Joe Biden, in an interfaith ceremony in 2012, linking him to the Biden family until their divorce filing in August 2025 after 13 years of marriage without children. Beyond clinical practice, Krein serves as Chief Medical Officer at StartUp Health, a venture platform investing in health technology startups, where his informal advisory role to the Biden campaign and transition team on COVID-19 matters—while his firm pursued government-related opportunities—raised documented concerns about potential conflicts of interest from ethics experts and media outlets across the political spectrum.
In brief
Krein's day job is faces — surgery, teaching, a clinic that repairs and reshapes. The side job is startups that want a doctor in the room.
Family ties put him near national campaigns; he has advised on public-health questions in an unofficial key. The operating room is the credential.
