Welcome to patient focused healthcare

Naturopathic Doctor Gilbert AZ

Our naturopathic doctors provide personalized, integrative medical care in an environment where we don’t just treat symptoms, we find root causes. Resolving your health concerns is only the first step in our care. We work with you to enrich your health and wellness on all levels – physical, mental & emotional.

Feel better than you ever thought was possible.

I’m Ready to Get Started

If you are looking for a doctor that truly listens – we hear you, and our doctors are here.

We provide an alternative to health clinics with long wait times and where you feel rushed. Most importantly, our complete focus is on our patients. Each initial consultation with our Naturopathic Doctors is 90 minutes, giving you enough time to share all of your health concerns. By talking through your extensive medical history, ordering comprehensive testing, when needed, our doctors can identify root causes so they can focus on treating you as a whole rather than treating individual symptoms.

If you have been told “your labs look normal” and are not getting solutions to your health concerns – we can help.

Some of the most common reasons patients seek out a Naturopathic Doctor include:

  • Poor outcomes with pharmaceutical treatments that have been prescribed by their conventional medical doctor
  • Wanting to spend more time with their doctor
  • Looking for a provider that treats their patients holistically
  • Seeking a doctor trained in alternative therapies
  • Establishing a long-term relationship with a doctor through their life’s health journey

When you are ready to heal your body, not just mask symptoms… our Naturopathic Doctors are here.

Naturopathic Doctors (NDs), also referred to as Naturopathic Medical Doctors (NMD), have training in conventional medicine and natural therapeutics. They practice integrative medicine which blends the best of both approaches. Naturopathic Doctors attend federally-accredited four-year post-graduate level medical schools and are trained in the same medical sciences and treatment options as Medical Doctors (MDs) such as pharmaceuticals, imaging, labs, etc. Our doctors use a combination of therapies that address the interconnection between your physical health as well as your mental & emotional well-being so you can heal on multiple levels.

Naturopathic Doctors Gilbert AZ

Initial Visit

Every new patient relationship begins with an open dialogue about the state of your health & well-being — emotional, physical, and mental. Here, our focus is gathering  your medical history,  as well as understanding your health goals in order to create a personalized treatment plan.

Treatment Plan

Together we will discuss what treatment options are best for your individual health needs and budget. This includes creating a comprehensive health plan to uncover and address the underlying causes of your symptoms.


Here’s What Our Patients Say:

Dr. Kasey Nichols took the time and effort to find the underlying cause of my chronic neck pain. During the examination and consultation it was apparent to me of his knowledge and expertise of what was causing my neck pain and his treatments helped me immensely, without having to use any pain meds. He is so easy to talk to and he explains everything so you understand why you are feeling the pain. I highly recommend Dr. Kasey.

Bernie U

Dr. Stephanie has been treating me for over 2 years and I have experienced immense improvements in my mental and physical health under her care. She is very approachable and I feel 100% comfortable sharing my most embarrassing symptoms with her. She really digs deep to get to the root cause of your symptoms and her treatments are seriously effective. It is so nice to go to ONE doctor who I know will assess my OVERALL health (yes, mental health too, it’s all connected!) and find long term solutions that work and are not just another prescription fix. It’s obvious that she actually cares and I’ve never trusted a doctor more.

Malorie U.

Dr. Stephanie Nichols is fantastic! I am so thankful to have finally found such a knowledgeable doctor. Dr. Nichols has used telemedicine to assist me through my first pregnancy. She has made the experience comfortable and stress free and I could not recommend her more. Her abilities as a Doctor and her gracious character were evident from the start and have grown with time.

Jessica Z.

Dr. Stephanie Nichols is a bright, energetic and compassionate doctor that is simply wonderful. I felt comfortable expressing my concerns and health issues. She was very thorough and knowledgeable. I would highly recommend Dr. Nichols.

Susan D

The absolute best and most thorough care you could possibly imagine. Dr Stephanie really knows her stuff, and always makes me feel like I’m in good hands.

Dustin S

Dr. Stephanie Nichols is one of the most caring doctors I’ve ever worked with. She combines her knowledge of Chinese medicine and other naturopathic modalities to treat the whole person. She was so caring when I had my initial intake with her and spent so much time asking me questions that no other doctor has. I can tell that she is not only passionate about what she does, but excels in her field. I’ve also received wrinkle releasers, micro-needling facials, and fillers from Dr. Nichols as well, which I had fabulous results with. I would highly recommend Onyx Integrative to anyone looking to change their health for the better!

S Michelle

I have been seeing Dr Kasey for my back and hip pain as well as my reflux for several months. I have been to a few other doctors and chiropractors with no relief. He has been doing acupuncture and my back pain is almost completely gone! He talked to me about how my stress and diet choices are affecting my reflux and we have been working together on both of those with herbs and diet changes. I completely off my medication and am feeling so much better. Dr. Kasey is caring and compassionate and I am now sending all my friends and family to see him!

Jolene K

Dr Stephanie is kind, patient and attentive. She is a very informative and caring Doctor and super easy to share with. Would def recommend seeing her to anyone seeking honest professional care.

Deanna R

When Dr. Stephanie’s practice was in Kansas I went to her. She helped me with my immune system. Acupuncture with gems helped me so much! She is so knowledgeable about the mind/body connection so Arizona is lucky to have her!

Kristin R

Dr. Stephanie is the only person I trust with my filler and dysport needs! She’s a true artist, and I’ve never felt prettier! After my last appt my husband could not stop looking at me and couldn’t put his finger on why “I was looking so beautiful”! Thanks Dr Stephanie! You’re the best!

Chanelle S

I would highly recommend going to see Dr. Stephanie Nichols. She is approachable and made me feel very comfortable, which isn’t always the case when seeing a new doctor. She is knowledgeable and happily answered all of my questions and concerns.
