Tanicia Reedon

Tancia's passion to become a Doula came to her at the age of 13 when her mother was pregnant with her sister. Experiencing first hand the ups and downs that flowed from pregnancy to birth (…and beyond), cemented her desire to care for mom and babies. After (literally) bumping into a midwifery student on the TTC one day she realized she could turn her passion into a career. Wellness is not a trendy word to Tanicia, it is an act of self-love and self-care, which is what propelled her to become a wellness coach. Being part of the OLS Community is such an honour!
