Our Providers


Rolf Habersang, MD, MPH & TM


Dr. Habersang's experience in Medicine and Healthcare is spanning over 4 decades. With initially a focus in General Pediatrics and Intensive Care for over 30 years he then followed many of the children with special health care needs as a professor with Texas Tech Medical School in Amarillo Texas. Because of his passion for helping individuals, children, and adults, to optimize their wellbeing he expanded his knowledge through continued training in Biological Medicine and Functional Medicine and now practices a holistic approach to health care based on the principles of Biological / Functional Medicine and Homeopathy. His "mantra" is  "YOU ARE WHAT YOU EAT and THINK".  


Dr. Habersang provides consultations to patients who have a variety of issues, though not in the context of primary care. 




Angie Chadwick, FNP-C


Angie Chadwick, a Family Nurse Practitioner,  joined the ICAM Institue of Amarillo in the fall of 2014 initially on a part-time basis, but now as a full-time provider. Her focus on primary care provides a newly added service to the ICAM clients who enjoy the concept of a holistic approach based on the principles of Functional Medicine. Any needed referrals for diagnostic tests etc. will gladly be made for established clients.


Angie's passion for health promotion for the whole family grew out of her work experience as a Neonatal Intensive Care Nurse at the Children's Hospital at North West Texas Health Care Systems in Amarillo Texas where she worked after earning her Bachelor of Science in Nursing in December 2008 at West Texas A&M University. She then pursued her Masters in Science of Nursing at West Texas A&M University, and ultimately was certified as a Family Nurse Practitioner by the American Association of Nurse Practitioners in 2011.

Laura Wright,  RN


Laura Wright, a registered nurse, has been with ICAM since 2007.

Her involvement with the ICAM clients covers a variety of aspects from consulting with them on proper implementation of the recommended treatments and interventions to administering the testing for Thermography, Qualitative Fluid Analysis, Body Composition Analysis or starting and supervising the  IV therapies.


Laura is also the major contact for the ICAM clients who seek answers regarding health care questions over the phone. When clients see her in the office her consulting approach may be complemented with the application of Psych-K,  an approach in which she has received extensive training over the past years whether it is for weight management or a variety of other issues.
