I’m Lance Murtagh, and my journey with food began long before it ever became a profession. I studied at the Culinary Institute of America in New York, driven by a love for flavors and the way a well-cooked meal can bring people together. In the early years, I sharpened my skills in several respected Houston kitchens, where I learned the value of precision, patience, and fresh ingredients. Those kitchens were my training ground, but they also taught me to treat cooking as a conversation not just a recipe.

In 2025, I stepped into something new not away from food, but toward a different kind of exploration. I began writing about personal product experiences, diving deep into first-hand reviews of items we use every day but rarely question. It was a natural transition. Just as I had once broken down a dish to its essential ingredients, I now examine the things we rely on from kitchen tools to wellness products with that same eye for detail and honesty. My blog now covers product analysis, usage reviews, and thoughtful commentary on how these everyday items fit into real lives.
