We listen to how you've been feeling, test your hormones, thyroid, cortisol and blood sugar together, and dig into what a single panel misses. Then your doctor walks you through every result and builds any therapy from your own levels, with you.
For women and men. In Gilbert, or by telemedicine nationwide.
Told your bloodwork is normal?
Sitting at the bottom edge of normal is still technically normal, and it can still feel awful. Here is what a single panel tends to miss.
Estrogen, progesterone, testosterone, thyroid and cortisol depend on each other. One reading alone rarely shows what's wrong.
Hormones move through the day and through the month. A single morning draw can miss the rest.
Sleep gets one prescription, mood another, weight gets advice. Nobody connects them.
Fatigue and low drive get blamed on getting older or having a lot on. Sometimes that's true. Often it's why nobody looked further.
For women
Dr. Stephanie Nichols, NMD founded Onyx and focuses on women's hormones. She listens first, because you know your own body better than anyone. The same marker reads differently depending on where you are in your cycle, so your testing is timed and read with that in mind.
When therapy fits, options include bioidentical hormones compounded to your levels, with follow-up labs to adjust the dose. You and your doctor pick the form that suits your life: creams, troches, injections, pellets, patches or pills.

My daughter has been dealing with hormone issues for a while. Dr. Stephanie listens to your concerns and explains things thoroughly. She is very knowledgeable and my daughter is very excited to be working with her through her healing process.
I have seen several specialists and doctors, and this is the first time that, after spending so much money and time, I have come across someone who is truly knowledgeable and genuinely interested in going deep into my case.
I've been working with Dr. Stephanie for almost 2 years and she's been the best doctor I've ever had. She's so understanding and truly cares about her patients.
She really listens to everything I explain to her. Her ability to ask the right questions of me in order for her to have an accurate picture of my health is comprehensive.
He sat with me for 2 hours while doing an IV hydration session and just talked to me, asked me questions, encouraged me, and gave me hope.

Book with Dr. ChelseaHow it works
Nobody hands you a standard protocol at the first visit. Your doctor won't know enough yet to build you a real one.
Your full history, your symptoms, your goals and what you've already tried. Bring any labs you have.
Your doctor orders the panel that fits. You draw locally at LabCorp, Sonora Quest or Patient's Choice.
Your doctor walks you through every result in plain language, and you decide on therapy together. Follow-up labs keep the dose right.
Usually not. Your doctor tests first and builds any therapy from your results, so the plan comes at your follow-up.
Bioidentical hormones compounded to your levels, in creams, troches, injections, pellets, patches or pills. For men, testosterone replacement therapy (TRT) or boosters that help your body make more of its own. Your doctor recommends one only when your history and labs support it, and goes over the risks with you first.
No. Bring any recent results you have. Your doctor orders the rest at your first visit.
Yes. We see patients all over the country by secure video, and you draw your labs near you. Telemedicine uses the same schedule as in-person visits.
Not for office visits, because no insurance plan lets naturopathic doctors into its network. HSA and FSA cards work.
