Next, we’ll meet over Zoom to walk through a customized plan I’ve created just for you—based on your lab work (if available), your detailed intake, and everything you shared during our discovery call. This plan is goal-oriented and designed to get results, but the process will also feel supportive and doable.
This is a collaborative approach. If something doesn’t feel realistic or aligned, we’ll adjust it together. You’re the expert on your body—my role is to guide you with the tools, insight, and experience to help you move forward with clarity and confidence.
This phase is where the real transformation happens. We’ll virtually meet every week to track progress, adjust your plan as needed, and work through anything that’s getting in the way. Most plans last around three months—enough time to build lasting habits, shift body composition, and see meaningful changes in labs and how you feel.
Consistent coaching and accountability are key—they’re what turn a plan into real, sustainable results. Communication between check-ins is always encouraged. You don’t have to wait for our next session to ask questions or get support. We’re in this together, and that ongoing connection is what helps make the changes stick.
After the initial phase, many clients choose to keep checking in—weekly, monthly, or as needed. Health isn’t static, and these follow-up sessions give you space to reassess, make adjustments, and stay aligned with your goals as life shifts.
You set the pace. Whether you want regular accountability or just a place to regroup when things change, ongoing support helps keep your progress on track and your plan working for real life.
Your metabolism is shaped by far more than food. That’s why we take a whole-body approach—addressing the nervous system, sleep, movement, toxic burden, and more. We support stress resilience, enhance detox pathways, and incorporate restorative practices like breathwork or meditation when helpful. Because the body is interconnected, our work has to be too.

Because everybody is different.

I feel better, mentally clearer, more energy.

What a gift.
