About me.

Product manager by day, triathlete and runner pretty much every other waking hour. I started racing in 2017 and have been chasing the next thing ever since — an ultra Ragnar relay, the Sea to Summit Adventure race, a self-supported marathon during COVID quarantine, my first Ironman in 2021, and a long string of weekends that have somehow turned into eight years.

Outside of endurance sports, you can also find me doing projects around the house, tending to our vegetable garden to support my love of cooking, or just relaxing on the couch with our two cats — Nero and Luna. I also come from a big Italian family that loves the outdoors, hiking and beach bumming in the summer, and skiing in the winter.

Fun Fact: I am a huge Oreo fanatic and have tried nearly every flavor ever released (Carrot Cake – amazing, Spicy Chicken – not so great).
