About Holly
Holly Pevzner is Yahoo's Health Editor, where she edits health and product review content, works closely with a network of vetted writers and testers, and personally evaluates products across categories, including mattresses, compression socks and sneakers. She also co-developed Yahoo Health's testing methodologies for mattresses, hair loss treatments and other wellness products. Every recommendation she makes is benchmarked against guidance from leading medical organizations and informed by more than 25 years of experience in health journalism. Her background includes senior editorial roles at Self, Prevention and Fitness magazines, regular health columns for First for Women and Prevention, and 10 editorial awards recognizing her work in health and nutrition. That experience shapes how she evaluates products — not just by comfort, convenience or price, but by how they may support readers' health and well-being. She's skeptical by nature: if the science doesn't support it, neither does she. When she's not evaluating mattresses or wellness gear, she enjoys the Los Angeles sunshine (with a hat and SPF) alongside her husband, two sons and rescue mutt.
