Healthy intentions are easy.Making them work in real life is harder.

I combine nutrition coaching, behavior change, and product design thinking to help healthier habits actually fit your life.

You probably don’t need more nutrition rules.

You may already exercise, try to eat well, and genuinely care about your health. Then busy schedules, stress, eating out, and decision fatigue make consistency surprisingly hard.

I know what I’m supposed to do. Why isn’t this working?

I’ve lived a version of this myself. That question is what pulled me into nutrition science, behavior change, and a lot of experiments.

Approached like a design problem.

I spent years in product and service design, including food-related work at DoorDash. The questions didn’t really change. The surface did.

  1. 01

    Understand the behavior. What is actually happening in your real life?

  2. 02

    Find the friction. What makes the healthier behavior harder than it needs to be?

  3. 03

    Test a small change. A realistic experiment, not an overhaul.

  4. 04

    Keep what works. Build on what feels useful and sustainable.

  5. 05

    Redesign what doesn’t. Treat setbacks as information, not failure.

The surface changes.The design process doesn’t.

How we might work together

I’m currently building this practice, and opening a small number of spots for early clients who want to experiment rather than follow a rigid meal plan.

  • Personalized 1:1

    We start with your goals, constraints, and what you’ve already tried.

  • Primarily online

    Sessions and check-ins inside your actual routines. Occasional Bay Area sessions may be possible.

  • Small experiments

    We test manageable changes, keep what works, and redesign what doesn’t.
