Mark Holtsschlag, DC, DACBN

Dr. Mark is a 1981 honors graduate of Palmer College of Chiropractic in Davenport, IA. He attended the University of Illinois Pre-Med Program and decided that drugs and surgery was not something he wanted to be involved with. After completing chiropractic college, he attended numerous seminars and received a board certification in nutrition and an advanced proficiency rating in Activator Methods adjusting technique.

Realizing the need for an effective nutritional system, he searched and found Ulan Nutritional Systems. He enrolled in the Nutrition Response Testing® program in February 2012 and graduated in 2013.

“Dr. DD Palmer was very aware of the nutritional needs of the body to heal and stabilize subluxation.  Environmental toxins and nutritional deficiencies were actually the cause of said subluxation. My desire to share Nutrition Response Testing stems from this very truism.  Through my 30+ plus years as a chiropractor, I realized that the nutritional component in chiropractic is vital.  And while other nutrition approaches exist, none comes even close to the results that we are getting with Nutrition Response Testing. In addition to daily miracles from Nutrition Response Testing, we also have learned the management techniques which have helped us to grow and track our growth.  We are seeing 3 times the number of patients from the time we began and with less stress.”

She earned her chiropractic degree, magna cum laude, in 2005 from Logan Chiropractic College in Missouri.

Dr. Call-Smith opened her first private practice in the town of Brookport, Illinois in 2005 where she served patients from Illinois and Western Kentucky.

Dr. Call-Smith is one of a limited number of health practitioners who have graduated a very extensive Advanced Clinical Training program in Nutrition Response Testing®. Nutrition Response Testing is used by thousands of health practitioners of all types and specialties across the United States including osteopaths, MDs, nutritionists, chiropractors, massage therapists and acupuncturists.

“Nutrition Response Testing allowed me to find that missing piece I was looking for as a chiropractor.  I had some patients that would just not get the results I expected with chiropractic that finally got better when we addressed the underlying nutritional issue.  I now have the tools to know which patients are going to be ‘difficult chiropractic cases’ and can get them started on a nutrition program to fix the nutritional imbalances along with chiropractic adjustments and we get awesome results! Nutrition Response Testing has improved my own health dramatically and allowed me to serve my patients even more.”

Sarah Wilkinson, DC

Dr. Wilkinson graduated from Eastern Michigan University in 2007 with e Bachelor’s Degree in Biochemistry and a Doctorate of Chiropractic from Life University in 2012. She came across Nutrition Response Testing back in 2010 and realized that this is what she needed to truly help her patients.

“Initially I had just opened my practice and was seeing only chiropractic patients. I slowly added nutrition patients as I began my Advanced Clinical Training (ACT) in Nutrition Response Testing®. After finishing ACT 1, I saw about 5 patients per week and now after completing ACT 9, I see about 55-60 patients per week just for nutrition.

I feel there is a definite need for Nutrition Response Testing within my community and my practice. It has improved not only the quality of my health but my family and my patient’s health. I also am certified by the Animal Veterinary Chiropractic Association and work with animals and see how this technology has improved their health as well. I knew that not only did I want to pursue my dream of working with animals but now I wanted to care for people too! Educating people on how to care of themselves and their kids, both 2 legged and 4 legged, in a natural way, has definitely become my passion. I think it is important to get the word out on how amazing our bodies are when given the right tools. We can actually heal ourselves without all the unnecessary medications and surgeries.”

Nichole Hirsch Kuechle, née Doula

Having served the Twin Cities as a Birth/Postpartum Doula, Craniosacral Therapist, and Lifestyle Educator for the past 20 years, the timing was right to bring on another level of care as a Master Clinician with Nutrition Response Testing®. What was needed was a non-invasive way of finding the underlaying causes for what our practice members were dealing with that weren’t getting handled any other way.

Commonly they dealt with digestion, headaches, thyroid issues, skin concerns, and infertility, and I was at a stop for how to get them managed and into a state of health….until I up-leveled my own health with Nutrition Response Testing.

I knew I needed to share the experience I had with my loved ones and clients. After years of struggling with multiple miscarriages, recurring UTI’s, cystic acne, stomach pain, awful cycles, and emotional stress, Nutrition Response Testing was the only modality that not only made the difference for me, but continues to do so over time. Getting my health back in 2014 allowed me to sustain another pregnancy and deliver our first son at home in 2015.

“Our physical bodies are made of basic elements in nature that promote the growth and survival of living things. The need for proper nutrition is of paramount importance in serving the body to restore full function with the ability to thrive. Nutrition Response Testing provides the most accurate way to define the specific nutrition that the body requires in a priority manner to maximize restorative power. It has been my joyful obligation to interest and instruct many practitioners in this work who now use the same techniques to successfully help their patients.”
