The Decades Ahead Summit
*New 2027 date coming soon!
I created this summit because I see women every day who are overwhelmed with information yet under-supported in understanding what truly moves the needle.
It’s One Day. But It Could Shape the Next 40 Years.

I help people stop googling their symptoms at 2am.
You don’t need to keep guessing your way through perimenopause into postmenopause. The truth is, midlife is a time of massive hormonal, emotional, and physical transition—and too often, women are left in the dark or dismissed entirely. Whether you're struggling with brain fog, low libido, sleep disruptions, mood swings, or simply not feeling like yourself, the time to get clarity is now. The sooner we address what’s happening, the better we can support not just symptom relief, but your long-term brain, bone, heart, and emotional health. This matters.
That’s where I come in. As a Naturopathic Doctor and Certified Menopause Society Practitioner, my clinical focus is in evidence-based care for women in midlife. I combine clinical expertise with personal connection, shaped by the real-life experiences of my mother, my aunt, and the thousands of women I’ve had the privilege to support. I sit at the intersection of science, strategy, and compassion—helping you make informed decisions about hormone therapy, lifestyle, and the kind of support you actually need. Because menopause care is more than a prescription.
Foundations
I like to always start with the foundations of health: nutrition, physical activity, sleep, digestion, and stress management. What are your current habits and routines that are stopping you from achieving your health goals? I will meet you where you are at. I will make sure that whatever treatment is provided is sustainable in the long run and resonates with you and your health goals.
Approach & Philosophy
Evidence-based
I am passionate about providing you with accurate, up-to-date, evidence-based information pertaining to your particular concerns. If there isn’t a whole lot of evidence for a particular treatment, I will make sure to let you know. A large part of my practice is education - making sure you understand the what, why and how of treatments.
Mindset
We currently live in a society that encourages doing and achieving. As a result, we lose the ability to focus in the present moment. You have the power to choose your thoughts and way of being. I am passionate about helping you take radical responsibility of your health, and this starts with your mindset.
What to expect
The initial appointment is 90 minutes in length. During this time, I will get to know your healthy history in more detail and we will set health goals for our time together. My goal as your Naturopathic Doctor is to help you reach your goals in a sustainable way.
Follow-up visits are between 30-60 minutes in length. We will check in on your ongoing plan and assess how you have been doing. We will make adjustments where needed. We may also address any new concerns that may have come up since our last appointment together.
I want to make sure that you feel supported throughout this entire journey. I will work with you as a partner in your journey to health and well-being.
