“It’s Best To Test Before You Buy…..Vitamins!”
WHY TEST? GUESSING IS RISKY, TESTING IS EXACT!
Have you wondered… What vitamins do I really need? Are my supplements really working? If so, why do I have a cupboard full of unused vitamins? Why do I think I need something more or different?
I provide a scientific Nutritional Evaluation and Clinical Nutrition Analysis of the Laboratory Reports from testing your biochemistry (blood, urine, hair, saliva, stool and genetics). Clinical Nutrition Evaluations and Testing will identify the exact vitamins and other nutrients your body needs to heal, maintain optimal health, reverse your biological age by 5-30 years and prevent disease. By heal, I mean to grow new healthy cells to replace malnourished, toxic, decaying and damaged that cannot be repaired.

Call me now at (940) 761-4045. Click on the “Supplements” Menu Tab for details.
- Personal Education Programs (PEP) – Just like the Law of Gravity, there are laws (or principles) that govern the healthy function of the human body; the same for animals, too. Therefore, I provide a personalized educational series of consultations and lessons on the Dietary, Lifestyle, and Mind-Body principles of biology, biochemistry, quantum physics, bio-energetics, physiology and psychology to assist you with everything you need to know to develop a healthy “principle-centered” lifestyle that promotes health and prevents disease.
That way, your lifestyle is in harmony with these principles. In other words, your lifestyle is working with these principles to build and maintain health, rather than living a lifestyle that works against them, causing you ill health and disease.
Since 1981, my New Client Survey has proven that even with all of the published dietary, nutritional supplement and lifestyle information online and in books, the public still only knows less than 30% of the information I provide in my Personal Education Program (PEP) on Dietary Principles, and much, much less than on Lifestyle or Mind-Body Principles.
30% means that the other 70% they need to know to develop a principle-centered healthy diet and lifestyle is unknown to them, except through an informed clinical nutrition health care professional, like me; and that lack of knowledge is causing or contributing to the development of their current health concerns. This is the #1 reason why people are still searching and searching. That is, until God leads them to my website and they contact me.
Additionally, most were not applying the 30% they did know. So my Personal Education Program (PEP) is also designed to help you implement these principles at your own pace until they become routine, permanent, unconscious daily practices, just like brushing your teeth. What do I mean by unconscious? If I asked you if you brushed your teeth today, you would immediately say, “Yes!”
However, more than likely, you would then pause and think, “Did I?” You brush your teeth so routinely without thinking or being conscious of doing it and that is what my Personal Education Program (PEP) is designed to do in all aspects of developing a principle-centered healthy lifestyle that promote health and prevents disease, every day!

My Journey
When I was 24, one of my roommates lent me a book on “Herbs.” I was not aware at the time that herbs and whole foods were God’s medicines. The first Herb from the book that got my attention was Yarrow. Why? I read that the flower tops of Yarrow make a hair rinse for blondes. A few months after switching my commercial hair rinse to Yarrow, the recipe below became a favorite request from the blondes in my church. Then I read something even more amazing to me — that applying the juice from crushed Yarrow leaves could instantly stop the bleeding of a wound. I wondered if that was true.
A few weeks later, on a beautiful Saturday afternoon, one of my church friends, her three-year-old daughter and I went to a nearby meadow to collect a batch of Yarrow flower tops to make more hair rinse for our “blonde” church members. (LOL) All of a sudden, I heard little Amy scream! She had fallen on a rock and cut her knee, blood was dripping all down her leg!
As I rushed to her, my fingers were crushing the leaves of the Yarrow I had gathered and I immediately applied the juice to her knee as soon as I reached her. AMY’S KNEE STOPPED BLEEDING INSTANTLY! As Amy’s crying subsided, her mother and I just looked at each other in AWE!
From that moment on I had the strongest, most passionate desire and dedication to learn as much as I could about the medicinal properties of Herbs. As my herbal knowledge increased, which included an Herbalist degree (C.H.), this journey lead me to acquiring knowledge and experience in organic farming, preserving foods without chemicals (such as dehydrating foods, etc.) and obtaining other formal collegiate studies in Naturopathy (N.D.) and Homeopathy, which was included with the N.D. studies, then knowledge in Dietetics (what to eat and drink) as Licensed Certified Dietitian-Nutritionist (C.D.N.), all the way to my Ph.D. in Clinical Nutrition and becoming a Board Certified Clinical Nutritionist (C.C.N.).
Nutrition is what is happening on the inside of the body as a result of what you eat, drink and are exposed to. So, Clinical Nutrition is “the” profession within the field of Nutritional Science that provides biochemical testing and therapeutic and health maintenance services to restore and maintain optimal health.
Even to this day, I am still that young-at-heart, passionate student of all things God has provided us for healing and wellness. And the stories I could tell you! ….. about how God has guided me in my personal life and in helping my clients, even miraculously, which includes the many miraculous, serendipitous events that transpired as God guided each of my clients to find me. Perhaps, it is not by chance that YOU landed on my website today.
As I continue to trust in God, leaning not upon my own understanding, but in all my ways acknowledging Him, God will continue to guide my path (Prov. 3:5-6), as He has since the day I was born… As He has since that beautiful, summer day that led me on this journey of healing. I eagerly await to see where He takes me next in this ongoing journey of love, grace, joy, healing and peace for myself and others. God is Good! Amen!
