Prior to founding Ecore Wellness, Evelyn served as a paramedic and EMS instructor, where she cultivated a deep understanding of traditional emergency medicine. This background uniquely positions her to bridge conventional and functional medicine—helping patients not only heal but thrive.
As a speaker, educator, and entrepreneur, Evelyn is passionate about transforming the way we view health—moving from symptom management to true cellular restoration. She has been featured in regional publications for her leadership in regenerative medicine and continues to partner with medical professionals to advance innovative care models.
