Lyn’s Journey

The profession of nursing has been a joy for me. Ever since I sat with our old dog as she was dying, I have felt the beautiful open space of being with others in their most vulnerable times.

My good fortune was to always be at the leading edge of where the profession was headed: first baccalaureate class at my university, master’s degree with a nurse practitioner focus just 8 years after education for NP’s began, nursing private practice in California in 1986, nearly unheard of at the time.

In private practice, and as a community health nurse, I called myself a nurse consultant since coaching had not been invented yet. 

Embracing the entire community with my services: I saw private clients in my office, consulted with nursing homes, spoke to an outpatient mental health clinic, worked with an industrial firm experiencing a high rate of on-site job accidents, worked with business organizations, held weekend workshops at the community center, did teaching and research at the community college. I even had my own radio show!

While living overseas, I experienced chronic illness and returning to the States, I became even more ill. Even so, I never lost hope of returning to my professional work. 

Upon regaining my health, I joined the American Holistic Nurses Association, volunteering as a chapter leader the same day. This allowed networking with many other like-minded nurses, and we formed a council for the chapter administration.

The nurses and health professionals on the council decided to come together to create a holistic nursing school and I realized that the Resilience Principles which I had shared in my private practice would be an ideal umbrella over all of the modalities and special practice areas of holistic nursing. 

I recall being at a session of the national AHNA conference when I envisioned and drew healing hands holding the young holistic healthcare system, and suddenly realized the hands were mine. I knew that the Resilience Principles and nurse coaching would transform health care.

Teresa’s Experience

Have you ever had something so big inside of you that you wanted to bring out into the world, but were too afraid to do it? That was me before I realized the power of the Resilience Principles. 

In 2015 I was at a low point in my life.  I was suffering from chronic pain, burnout, and dissatisfaction with life.  I saw no end to my circumstances.  

Then, in October 2015 I attended our 5th Annual Texas Regional Holistic Nursing Conference, where I met Dr. Keith Blevens.  He described how thought works.  Not my belief about how it works, but how it really works as a fact.  He described it as inside-out.  A natural paradigm of how our mental life works.  

To be honest, I don’t think I completely understood what he was talking about, but it made sense.  I experience life in only one way, my thought attached to my feeling creating my life.  It was so simple. 

Then he talked about separate realities.  We all experience a separate reality of life.  That made sense. 

Then something happened, I experienced those words in my body and at the moment of insight, I felt a tingling go down my back and out my arms and legs and the pain I had been suffering from disappeared.  I now call it a side effect of insightfully understanding these Principles at a deep level.   

I suddenly “knew” I had to share the Resilience Principles with people. 

Lyn and I had an insight into how to do that.  We were going to bring the Principles to people through Nurse Coaching–a new board certification for nurses. We signed up for a nurse coaching program and six months later we opened Advancing Nurse Coaching continuing education program.   

I am excited to be on this journey to help other nurses and our profession not just heal but thrive.
