Dr. Alexandra Schulthess, ND – Boulder Creek, CA

I am a Naturopathic Doctor from Switzerland, ANMCB/ANMA Board-Certified Doctor of Natural Medicine,

I love everything that being a Doctor of Naturopathy encompasses.  I intertwine my love of nature, helping others, exploring, and my deep yearning of becoming a “mad scientist”

I’m certified in Functional Medicine and Functional Nutrition.

In addition, I have taken advanced training in lifestyle medicine for the past 6 years, and, I’ve been also working towards my certification in Functional Neurology at IAFNR/ NUHS for the past two years. Over the course of my professional career, I have also attended numerous courses in Integrative Medicine, Diagnostic Laboratory training, detoxification, Biochemistry & Genetics, Clinical Nutrition, and Childhood & Neurodevelopment disorders.

My training included a Functional Medicine approach to gastrointestinal dysfunction, immune dysregulation, chronic infections, hormone imbalance, cardio metabolic syndrome, HRV, stress management, toxins, structural imbalances, auto-immune & neuro-degenerative brain conditions,weight loss,  food sensitivities and nutritional therapy, and detox.

I sought out further training in integrative and functional medicine from mentors such as Dr. D. Pompa, Dr. Dan Kalish,Dr. Robert Melillo, Dr. David Perlmutter, and my friend and mentor, Dr. Rita Mettler, DO in Switzerland ….

And I have recently been trained and now offer the True Cellular Detox program for my patients and clients.
I’ve been devoted to helping individuals restore their health and maintain enjoyable, healthy lifestyles for over 20 years.

I began my career in health care by working with pregnant & nursing woman in a small office while attending college.

I have owned my own private healthcare practice for 2 1/2 years here in the US and had a unique combination of in-office and virtual patient care experience. I’ve been passionate about using Functional Medicine focus on the root cause and a personalized approach to help my patients and clients prevent and reverse disease and achieve optimal health.

I specialized in Functional Medicine, True Cellular Detox, Functional Neuro-Integrative & Metabolic Assessment and Therapy.

Prior testimonials:

I am a patient of Dr. Alexandra for almost two years. She is knowledgeable and up to date on ways to encourage, treat, and educate her patients about functional medicine and a healthier life style. She is constantly advancing her knowledge as well by taking classes and seminars. Her office is a most pleasant place, quiet and peaceful. It’s a joy to be one of her patients.”

My name is Alex, and I am a Masters student at Stanford. Dr. Alexandra Schulthess is extremely knowledgeable in functional medicine, and she offered me great advice to optimize my health. We discussed a wide-range of topics, including medical literature and the top supplements that patients should be taking. Overall, I highly recommend her services to all others.

I have known Dr. Alexandra for 2-1/2 years and during that time have become more and more amazed at her training, thoroughness, and professionalism. She perseveres until she finds the answers… all of them. Her knowledge of the human body and psyche is unsurpassed. And she is a delight to be around. I always come away encouraged and hopeful. Well worth the drive. A beautiful, peaceful setting too! Make it a retreat day!

If you are NOT a New York resident, your initial visit at Functional Diagnostic Medicine must be in person. After the first visit, all follow up visits can be conducted by phone or virtually using our secure video channel if you choose.

For many of our patients, we cannot take the place of a primary care physician.

It is important to note the following however:

1. We do not fulfill an insurance company’s requirement for an in network primary care physician as we are not in-network with any insurance plan.

2. We are not available for same-day acute emergency appointments, please call 911 or your primary care doctor.

3. We do not have a 24-hour answering service and do not take calls on weekends. If you need to be seen urgently or have a medical emergency you would need to visit an ER or urgent care center.

The cost of any services provided by Functional Diagnostic Medicine which are not included in the episode of care fee will be billed to you directly.
Non-Functional Diagnostic Medicine medical expenses such as lab tests and prescription medications may be covered by a member’s health insurance plan per that plan’s rules.

Functional Diagnostic Medicine will not submit a medical claim to insurance on your behalf. We cannot assist you with claim resolution for our services.

We will provide you with a detailed billing summary that you may submit to your insurance for reimbursement. There may be procedures or lab tests that are not covered depending on your plan’s rules.

-Few lab tests ordered by a Functional Diagnostic Medicine physician will be billed directly to your insurance by the lab.
-Most lab tests we offer as part of our functional medicine testing program may not be covered by insurance and in these cases you will be charged a fee for a particular test by the lab or through Functional Diagnostic Medicine.
-The specific tests ordered will be personalized to you based on your initial evaluation with an Functional Diagnostic Medicine doctor and may include blood saliva urine or stool testing.
-We will make every effort to make you fully aware of any additional lab fees that may be incurred and to give you the opportunity to choose which lab tests you feel comfortable paying for.
-You are under no obligation to purchase any specialty testing.
Should any lab results indicate you may need further testing you will be directed to continue your care with your primary care physician or a relevant specialist, or should you choose you may continue to work with your Functional Diagnostic Medicine physician.
-At home test kits: If a lab test kit is mailed to you by Functional Diagnostic Medicine, you will be charged the day the kit is mailed.
-If your particular insurance company only pays for blood work done at a particular lab facility like LabCorp, you must inform us of this in advance of having blood work done. Most insurance plans cover labs done by major national labs – however, including Bio-reference, which is a lab often used by Functional Diagnostic Medicine Health because of their favorable pricing policies for patients.

There is a 24-hour cancellation policy for all appointments with an Functional Diagnostic Medicine doctor, health coach, or team member. Canceling within 24-hours will result in a $50 charge to the credit card on file.

No-shows: If you do not show up to a phone, video/telemedicine or in person appointment without notifying the specific person you have an appointment with either via email or by changing the appointment using the online scheduling tool on the patient portal, you will be charged $100 to the card on file.

I do not prescribe or make recommendations about prescription medications or controlled substances. Your prescribing medical doctor will manage all medications. I use natural, noninvasive methods such as nutritional therapy, herbs, supplements, stress management techniques and lifestyle changes to address the underlying causes of disease and promote optimal function and health.

Therefore, I do not practice medicine and do not diagnose or treat diseases or medical conditions. I focus my practice on promoting health and optimal function. My services are not meant to substitute or replace those of a medical doctor but my programs are meant to work in conjunction with them.
