Mizener
Product leader with 10+ years building digital experiences for tens of millions of users. I lead global teams with genuine customer empathy, a data-driven mindset, and a hands-on approach to understanding what people actually need. I care about the details, deliver outcomes over output, and utilize AI tools daily - not as a novelty, but as a real part of how I discover, decide, and deliver.

About
Most recently as Product Manager at Planet Fitness, I led the product vision to expand digital services internationally, delivering experiences to over 21 million members across 7 countries. I have a proven track record of building new capabilities that drive sales, retention, and engagement, and I bring years of practice communicating complex product work through release notes, tutorial videos, and stakeholder presentations that actually land.
I believe in using every tool available, including AI, to research deeper, prototype faster, and deliver better outcomes. I use AI daily to sharpen thinking, stress-test ideas, and move from concept to something tangible quickly. It's part of how I work, not a talking point.
Outside the office, when I'm not with my family I'm usually learning a new skill or building something with my hands. Lately that's meant exploring homelabs and local AI, experimenting with 3D modeling and printing, and spending time woodworking and sewing. If there's a new problem, I'll find a way to solve it.
My Product Values
I meet customers where they are, listening with empathy and starting with the ‘why’ to understand the real problem. I champion the voice of the customer internally, keep them informed on the roadmap, and build relationships that evolve as their needs do.
I believe in building lean and shipping with MVP in mind, then iterating based on real feedback. I close the loop post-launch, track the metrics that matter, and ruthlessly reprioritize to maximize impact on the things that actually move the needle.
I lead with trust and deliver outcomes over output. I want the people I work with to do the best work of their careers, and I want the products we build together to be valuable, intuitive, and genuinely memorable to the people who use them.
