Kelly Mandery, CMA
Certified Medical Assistant
Kelly began her career as a Medical Assistant in 2013 when she graduated from Kaplan College. She worked at St. Vincent Hospital as a Medical Assistant for 2 years. After working in traditional medicine, she became frustrated with treating symptoms rather than finding the root cause. Therefore, she felt the need to pursue preventative care which led her to integrative medicine. Kelly joined the functional medicine field in 2016 which led her to The Guyer Institute. Dr. Guyer quickly noticed Kelly’s potential which pushed her to go back to school. She is currently enrolled at Trinity School of Natural Health to pursue her Naturopathic Doctorates Degree. Following her dreams of healing others, Kelly plans to begin seeing her own clients in the near future!
In her free time, Kelly loves spending time in the gym with her husband, grounding with nature, and creating memories with friends and family.
