Catherine Onuoha
PhD, RPh, BCPP, CPh

Professional Thermographer and consultant pharmacist Dr. Catherine Onuoha was classically trained to appreciate Western Medical techniques at the Medical College of Virginia (MCV).  The PhD she earned at MCV is a dual discipline doctorate in Pharmacology and Toxicology.  After receiving her PhD, Dr. Onuoha pursued pursued a research position in the field of neuroscience at the Walter Reed Army Institute for Research (WRAIR).

Once her research at WRAIR was completed, Dr. Catherine found work in academia to be rewarding. Dr. Catherine held professorial posts for more than a decade, teaching within public and private institutions. Her teaching charge was to educate fledgling professionals across many medical specialties (Pharmacists, Nurses, Doctor of Orthopedics, Anesthetists, and Physician Assistants).

Throughout her academic years, Dr. Catherine dedicated some time each week to consultations with a patient base either within hospital clinics or in outpatient settings. Patient care continues to hold priority in Dr. Catherine’s work week. She is passionate about providing her patients compassionate, need-based medical care from a functional and natural healing perspective.

Although Dr. Catherine portends professorial work is meaningful, in fact, she loved it–a wee voice of intuition began working within her during 2014. To honor and trust this intuition, she began searching clinic work environments and was resolute in her quest to devote all of her time to patient care.

In January of 2015, Dr. Catherine joined Carol Chandler D.O.M. at the Natural Medicine Center of Lakeland. The two formed an easy collaboration since they share a similar vision of homeopathic healthcare in accordance with Natural and Alternative Healthcare methods.

Carol Chandler, D.O.M. and Dr. Catherine collaboratively have continued the tradition of utilizing Thermography as a powerful discovery tool to help clients far and near our community to achieve optimal health. Dr. Catherine is professionally trained to use Thermography as a unique tool to transduce physiologic changes. Dr. Catherine secondarily completed a rigorous training regimen under Dr. Carol Chandler a Doctor of Oriental Medicine and Master Herbalist.

Since April of 2015 Dr. Catherine has assumed responsibility for running the Natural Medicine Center of Lakeland and seeing patients here at this clinic.  While Dr. Catherine sees patients here at NMC and runs the day to day operations, she is assisted by her physician supervisor Doctor Justin Strittmatter who oversees medication/treatment decisions.

Traditional Chinese Medicine (TCM)

Traditional Chinese Medicine can be utilized as an alternative for patients with chronic conditions, who do not respond to western methods, or cannot use drug therapies due to sensitivities. It is particularly beneficial to those patients with pain, who cannot undergo surgery or anesthesia.

 The holistic approach of the Traditional Chinese Medicine is comprehensive, and assesses the individual patient as a “whole person”, instead of treating symptoms. The goal is to assess all contributing issues, that may affect the patient and their state of wellness, and to create a treatment plan to bring the mind, the body, and the spirit into harmony and balance once again.


Dr. Nam has also authored a number of books on acupuncture and Eastern medicine:
