History & Future

In the early 1980s Susan McCrossin, A.P. and Charles Krebs PhD. traveled to the United States to learn Applied Kinesiology (AP) from Richard Utt. Richard created AP after years of his own health issues; and after learning Applied Kinesiology (AK) from Dr. Sheldon Deal, D.C. Many of these amazing doctors and innovators became part of the "Touch for Health" movement and developed treatments based on the principles of Applied Kinesiology. AK uses the Chinese meridian system, Indian chakra system, lymphatic and vascular points, and muscle monitoring to heal the body. The AP work Richard created went on to link specific physiological pathways to sequences of acupressure points beyond the AK model. Susan and Charles studied with Richard Utt and then took his amazing work back to Australia.  In 1988, they developed Brain Integration Technique (BIT), and Learning Enhancement Acupressure Program (LEAP) from the foundations of neuroscience, AK and AP. In 1998, Susan McCrossin brought this work to the United States and started the Learning Enhancement Center in Boulder, Colorado. I met Susan McCrossin in 1998 and received BIT from her for my own learning issues. After completing my naturopathic medical training in 2004, I joined Susan McCrossin in her practice as a Naturopathic Doctor (ND). I relished this opportunity to work directly with her because it had changed my own ability to learn in such a dramatic way. I completed my BIT training and integrated these techniques in my own practice as an ND. I couldn’t imagine being a doctor without this important tool. I was in the first American class to receive Brain Integration Technique certification in 2006.

Dr.Pratt is a great team player and her work complements the other therapies and approaches we follow in conjunction.

- Parent of Autism Spectral Disorder Patient

Apart from BIT, Dr.Pratt's vast knowledge of the biomedical basis of ASD helps support parents as they try to heal the child's body in helping the brain develop.

There were such significant changes in my child's behavior after Dr. Pratt’s treatment, that it absolutely changed his life and the whole family.

- Behavioral Issues and Family Naturopathic Care

I have to say, I have never seen anything have such a positive impact on someone's life.

- ADD / Memory Recall Patient

Dr. Pratt's approach was friendly, relaxing, reassuring and non-invasive, and the progress that we saw in our son's writing was immediate and remarkable.

- Specific Learning Disability Patient

I would highly recommend Dr. Pratt’s nurturing, life changing treatments to anyone who desires a better, easier way of living in this world.

- Anxiety / Learning Disability Patient

Dr. Pratt’s treatment made it possible for my daughter to go to school full-time for the first time in two years, and as a matter of fact, she’s now talking about going to college instead of worrying that she’d never graduate high school.


- Patient of Head Injury Patient

Since my first appointment with Dr. Pratt, I have come back to her for every ailment. She has quickly and effectively cured every sickness I have experienced.

- Naturopathic Medicine Patient

I am working 4 days a week and I accomplish more in a day now than I did in a whole week before. I feel productive and useful after BIT.

- Head Injury Patient

It has not all been easy, changing your lifestyle and diet is a challenge but we feel very supported by Dr. Pratt. It's a long road to recovery but the rewards are great along the way. My son has almost recovered from his symptoms and we owe all of this to Dr. Pratt. We are very thankful to have crossed her path at the right time in our journey.

Dr. Pratt is compassionate and well-informed about the various challenges and available options for children with special needs. She is always willing to brainstorm options with parents and has a way of getting through to the children.

It is almost impossible to explain the dramatic and positive effect Dr Shelese Pratt has had on my health. It is without exaggeration that I say Dr Pratt has saved my life on numerous occasions. To say her work has dramatically increased the quality of my life is gross understatement. There is not an aspect of my physical, mental, or emotional health that Dr Pratt has not addressed at some point during my years as her patient. I first saw Dr Pratt in 2005, after suffering one infection after another over the course of three months and had exhausted my known medial avenues. She was the only doctor to see the connection to between all of my symptoms and to care long enough and deep enough to get to the bottom of them. I have sent countless loved ones and colleagues to her over the years and know that the level of her care has changed their lives for better without exception. I have had the privilege of seeing Dr Pratt for Brain Integration, naturopathic, and homeopathic treatments and I can say without any reservation that I credit my health and well being to her and her practice.
