β€” J.H. (Google Review)


⭐⭐⭐⭐⭐ β€œAfter my 1st appointment I felt hope...”

β€œDr. Thorne has had a monumental  impact on my health. I have seen several physicians for years, trying to get a solid treatment plan for severe endometriosis and PCOS. For years, there was no progress and treatment was minimal. My friend recommended Dr. Thorne and after my first appt with her I felt hope. Over several months, we created a treatment plan and finally got to the bottom of why it was so challenging to achieve disease management. She was quick acting, which I needed as my health was declining. It was very collaborative and I felt heard for the first time. I have had an incredible amount of relief and symptom resolution, thanks to Dr. Thorne. Truly cannot say enough good things about the impact she has had on my quality of life. I’m so grateful!!! 10000/10 recommend. .”

⭐⭐⭐⭐⭐ β€œShe does an excellent job of explaining the 'why'”

Dr. Thorne is the standard for what your health provider should be.

Frequently Asked Questions (FAQ's):

What are the Costs of Services?

***Dr. Thorne can still order blood work that can be billed to insurance.

However,  Dr. Thorne is  not in-network with any insurance companies or medicare programs. Dr. Thorne DOES offer a "Superbill" after each visit for patients to submit to insurance for partial reimbursement depending on their healthcare plan. 

Payment is still due at time of service.

If you are planning in using a Superbill, you will want to ask your insurance company what the coverage is for an "Out-of-network provider" and what they would cover for a "99204 and/or 99214" coded visit.

New Patient Visit (60 min.) *2 + health concerns: $400

New Patient Visit (45 min.) *1 health concern: $325

Can Dr. Thorne be my Primary Care Physician?

No, Dr. Thorne is not operating as a Primary Care Physician and has instead chosen to specialize in conditions listed above.

Dr. Thorne requires and recommends that all patients see a PCP at least once a year for their annual physical since Dr. Thorne is exclusively virtual.

Does Dr. Thorne Accept Insurance?

***Dr. Thorne can still order blood work that can be billed to insurance.

However,  Dr. Thorne is  not in-network with any insurance companies or medicare programs. Dr. Thorne DOES offer a "Superbill" after each visit for patients to submit to insurance for partial reimbursement depending on their healthcare plan. 

Payment is still due at time of service.

If you are planning in using a superbill, you will want to ask your insurance company what the coverage is for an "Out-of-network provider" and what they would cover for a "99204 and/or 99214" coded visit.

Are there only Virtual Appointments?

VIRTUAL TELEMEDICINE ONLY. Dr. Thorne works with all of her patients virtually. There are no in-person visits available at this time. This is part of the reason that Dr. Thorne recommends or requires that all patients have a PCP do a physical exam at least once a year, and stay on top of mammograms, colonoscopies and other routine exams. 

What Type of Hormone Replacement Therapy is Prescribed?

The bulk of HRT prescriptions are available at your local pharmacy and are considered "body identical or bio-identical." This includes: Estradiol patches (topical), sprays and gels for systemic symptoms, and vaginal estradiol cream or tablets for vaginal dryness. Dr. Thorne utilizes oral micronized progesterone shown to prevent endometrial overgrowth while using system estrogen. These therapies are FDA approved and often covered by insurance. For patients requesting compounded medications due to allergies or preferences that option is available as well.

NON-FDA approved therapies for women include topical testosterone cream from a compounding pharmacy and oral or topical DHEA and progesterone.  

The medications and hormones listed above are not an inclusive list and there are others not listed.

What is a Functional Medicine and Naturopathic Doctor?

As both a licensed Naturopathic Doctor and a Certified Functional Medicine Practitioner, I bring a unique, integrative approach to hormone health. Naturopathic medicine emphasizes root-cause healing using natural therapies like nutrition, botanicals, lifestyle, and mind-body medicine. Functional medicine builds on this foundation with a systems-based, personalized approach that uses advanced lab testing to identify imbalances and target therapies with precision. For my hormone patients, this means you'll receive deeply individualized care that blends the best of traditional wisdom and modern scienceβ€”addressing the "why" behind your symptoms, not just the "what," and creating a clear, holistic path to long-term balance and vitality.
