My goal is to promote healing through the wisdom of nature with gentle, evidence-based therapies to achieve balance for your best you.

While I studied botany and the medicinal plants in the Ozark Mountains at the University of Arkansas, I began to realize the potential and great need for Naturopathic medicine with my research. After finishing my pre-med biology degree and Master of Science, I attended Southwest College of Naturopathic Medicine to pursue my Doctorate in Naturopathic Medicine. This allowed me to complete the knowledge to fully support the healing process and teach individuals that have been looking for a positive change in their health.

I am honored to provide sustainable and quality healthcare that is effective, gentle and supportive to encourage your body’s ability to heal itself. 

I look forward to providing Naturopathic Medicine to you and your whole family.


Healing is a matter of time, but it is sometimes also a matter of opportunity.”

I feel I have come full circle. I graduated with a nutrition degree from Truman State University, and found myself working in sales and moonlighting as a waitress in a greasy Mexican Restaurant… I was frustrated!!  I quickly decided to go back to school to become an RN. I thought I was going to be able to help people attain health, but really, I worked in an ICU and watched too many very young people pass.  This wasn’t what I was looking for. I want to impact lives before it gets to this point.  So, I became a Nurse practitioner, looking forward to earlier interventions and health promotion, but instead I found myself handing out a prescription for every symptom instead of fixing them. I wasn’t helping patients at all! I was just covering up a sign from the body that something was wrong.  During that time, with the fast pace and long hours, I too got sicker and sicker. By the end of each long exhausting week, I had no energy left for my family. I felt miserable. I wasn’t living my authentic life anymore, and I definitely wasn’t thriving.

That’s when I realized that I had to change, I could do more. So, now, I work with patients to get to the root of the problem and figure out what works, not just hide symptoms. There is more to health than having to take a prescription for all of your diagnoses. There is more to life than settling for feeling miserable day in and day out.

I help people achieve their optimal health, and I get to do this every day. Nothing makes my heart sing more than hearing a patient say how much better they feel after making a simple change.

I’m Angela. I love life. I love helping people. And I’m so excited to be able to help you from wherever you are, get to wherever you want to be.

I used to hate broccoli.

            I grew up with my parents ingraining the mantra “finish your plate”, and inevitably, vegetables were battles. Even as I got older, I would rather reach for a cookie over a second helping of salad.

            While working in a hospital in my hometown, I provided care for chronically ill patients, many of whom plateaued or declined in their health. In those moments, I realized that I wanted something better. That’s when I began eating broccoli.

           I studied biology and psychology at Rockhurst University in Kansas City, MO and then attended Southwest College of Naturopathic Medicine in Tempe, AZ, obtaining my Doctorate in Naturopathic Medicine, graduating with honors.

          Now, I continue my journey. I believe in challenging the status quo when it comes to healthcare in order to determine what truly works for each person. I want to change the way you receive medical care. I want to change the way you see your health. 

              I am focused in medicine that integrates both cutting-edge modern therapeutics and the ancient knowledge of natural medicine. My passion is to create a partnership between doctor and patient, encouraging the patient to become a steward of his/her own health.  I work with patients to help them attain their health goals and feel their best.

              I’m a bit of a bookworm as I love to read. But when I’m not curled up in a good book, you can find me painting, hiking, running, and laughing with my friends at every possible opportunity.

             I look forward to working with you on your journey to health.

The reason I’m so passionate about helping others eat well is that I have experienced the healing power of food firsthand. 

At the beginning of college, I had little interest in nutrition. Ice cream, peanut M&M’s, Mountain Dew, and frozen pizza were regular parts of my diet. Then, a nasty virus triggered what would turn into many years of chronic pain, fatigue, and digestive troubles. My quest for healing taught me the importance of nutrition and the incredible difference that good food can make in our bodies.

I couldn’t keep that knowledge to myself, so I decided to become a Registered Dietitian Nutritionist. I obtained a bachelor’s degree in Nutrition and Dietetics from the University of Central Missouri and then went on to complete my dietetic internship and master’s degree in Dietetics and Nutrition from the University of Kansas Medical Center.

In order to better help others transform their health through nutrition, I wanted to deepen my understanding of using food as medicine. I completed a graduate certificate in Dietetics and Integrative Medicine and a fellowship with the University of Kansas Integrative Medicine clinic.

As an integrative nutritionist, I believe in individualized nutrition that addresses the root causes of chronic illness. I’ll help you discover and adopt the best eating habits for your body. Making dietary changes can be tough (I know – I’ve done it!). I’m here to help my patients achieve lasting wellness with down-to-earth, practical nutrition. 

When I’m not helping you change your food life, I like to read, practice yoga, play tennis, take long walks, and spend time with my husband. I can’t wait to partner with you to achieve a nourishing diet, healthy body, and happy life.
