Melinda is our newest addition to our administrative staff. She comes to Quantum Functional Medicine highly qualified to handle any and all situations with the greatest ease and a comforting smile.

She brings with her over 25 years in customer service in the fields of banking, finance, and real estate. Although her previous professional experience has not been in the field of medicine, she has always had a deep rooted, spiritually guided interest in health and wellness education, physical fitness, nutrition, kinesiology and all the functions of healing our bodies. Melinda has a great passion to help others (as well as herself) to seek spiritual and physical health. She delights in helping people to enter into (and grow in) a relationship with Christ Jesus.

Morgan Rich


As one of the newest additions to our staff, Morgan serves as scribe to Dr. Winkler, as well as providing ancillary services to our patients. She was born and raised in Southern California and completed her Bachelor of Science in Biochemistry and Cell Biology at University of San Diego, California. Morgan started her career in medicine assisting in the treatment of animals, which lead to her a vast background in veterinary medicine. It was while working with a European holistic equine vet that applied alternative practices, such as mesotherapy and PEMF to his patients that she discovered her love for functional medicine. His practice of holistic medicine served to pique her interest in exploring the functional integrative model of practicing medicine in human health care. Since then, Morgan has been working alongside of Dr. Winkler and the Quantum Functional Medicine staff in lovingly caring for our patients. She has plans to continue her education to obtain her doctorate, and her experiences here are helping her to decern which avenue she will pursue her doctorate in. When Morgan is not at work, she enjoys horseback riding, hiking with her border collie, and gardening.
