Carolyn R. Walker, MSN, ARNP
Owner, Prevention & Healing of Iowa

Carolyn R. Walker, MSN, ARNP Carolyn is currently a licensed nurse practitioner and owner of Prevention & Healing of Iowa. The majority of her practice involves family practice, women's health issues, detoxification and infectious illness in the context of functional medicine. She graduated from the University of Iowa in August 2000 with a Master of Science in Nursing and is board-certified through ANCC as a Family Nurse Practitioner. In 1986 she graduated with a Bachelor of Science in Nursing from Grand View College in Des Moines, IA.

Carolyn attended The Institute for Functional Medicine's "Applying Functional Medicine in Clinical Practice" for an intensive one-week course in Dallas, Texas in March 2006. This means she is evaluating the body's chemistry and restoring function with missing nutrients rather than treating symptoms solely with standard drug therapy. She attended this venue with Sue Horton, owner of Central Iowa Compounding and two other Central Iowa physicians. She formed her Functional Medicine clinic, Prevention & Healing of Iowa in 2006.

Carolyn was awarded a Health Professional Scholarship by the Veteran's Administration in 1985 and worked her first two years after her BSN in the Veterans Hospital system. From 1988 through 1997 she worked several years in home health care nursing as well as a school nurse and a home-based nurse consultant for a major insurer. She has been certified in Community Health nursing through ANCC since 1991 and enjoyed coordinating health-related presentations for homebound aging residents of assisted living centers.

Marty Rhea, ND, MH, CNC, CNHP
Naturopathic Doctor, Master Herbalist, Certified Nutrition Counselor, Certified Natural Health Professional

Marty Rhea, BA Marty Rhea received a Bachelor of Arts degree at the University of Texas at Dallas in Interdisciplinary Studies with emphasis in Science and Math in 1997. While pursuing a degree intended to result in further medical education, Marty worked as a nationally certified pharmacy technician at a retail pharmacy in Plano, Texas. In completing the Bachelor's degree, the responsibilities of four teenage children prevented the commitment required for further medical education at that time and Marty continued working until moving to Des Moines, IA in July of 2000.

After moving to Des Moines, Marty decided to apply to pharmacy school to further use her knowledge in health care. She was accepted to Creighton Pharmacy School, but once again, after weighing requirements for school against family needs, she decided against dedicating the required time and finances to complete a Doctor of Pharmacy degree. In 2004 Marty traveled to Albany, Ohio to learn the practice of BioAcoustics research from Sharry Edwards, the founder of Human BioAcoustics research. She also completed coursework to become a Certified Natural Health Professional in 2009. The CNHP allowed for many other opportunities for education for Marty as well. One of the first training courses Marty completed after becoming a CNHP was to study under Dr. Howard Loomis to become a Loomis Digestive Health Specialist.

In August of 2011 Marty completed her Naturopathic Doctor degree, Master Herbalist Certification, and Certificate in Nutrition Counseling. In October Marty took her boards and became a Board Certified Naturopathic Doctor.

Owner, Prevention & Healing of Iowa
"Over 20 years ago (1995) I did not believe I would have been alive today. Symptoms were occurring which I had never experienced before and those I had had were worsening. There were afternoons where I was totally exhausted and would have to put on an alarm clock for a nap just to get me through the evening. A new symptom of depression was creeping into my life which I had not experienced before. I was constantly cold, hair thinning, gaining weight, had heart palpitations, fibrocystic breasts and could not sleep at night. I prayed to live long enough to see my children into their adulthood.
