Kimberly Khaylov


Kimberly was born in NYC and grew up in New York State. She felt called to follow in her family’s career footsteps of nursing, making her the third generation of nurses in her family. She obtained her Associates Degree in Nursing at Westchester Community College and completed her Bachelor of Nursing at the University of Rhode Island. She has been a Registered Nurse since 2017. Kimberly is a compassionate, spiritual, and caring individual that aims to always provide a warm and a gentle approach to her patients. Kimberly has diverse nursing experiences which include rehabilitative nursing and medical surgical telemetry. While on vacation (escaping the New York winter) she fell in love with California and made the cross country move to make San Diego County her home. When not in her nursing role, she is a wife and a mom to two young boys. She enjoys dancing, exercising, shopping, reading, and is active in the children’s ministry at her home church.

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.
