Mark is Fathercraft's co-founder and dad to Hank, 2, and Dean, who just arrived in April. He started reviewing baby gear when Hank was born and has since tested everything from strollers and monitors to carriers, bottle washers, and smart cribs. He spends months using gear in everyday family life, comparing products head-to-head in multi-month head-to-heads: one stroller at the farmers market this weekend, another the next. Family trips take the testing through airports, onto planes, and into hotels and Airbnbs. A data nerd and project management junkie, Mark keeps detailed notes and spreadsheets to track it all. His wife weighs in, too. They still like each other after two kids, so the feedback is mostly about the gear and only occasionally about why there are 9 travel strollers parked in their entryway. Mark lives with his family in Phoenix, Arizona.
