Jada Taline Foster is a Sexual Health and Healing Coach who holds a BA in Media and Communications and is currently pursuing a BS in Human Sexuality and Women's Studies. She was born into a family of healthcare practitioners—in fact, she would have been the fifth generation of nurses in her family had she not chosen an alternate route by certifying as a personal trainer and yoga instructor while earning her degrees. Jada now coaches women who have experienced sexual trauma of all forms. She works tirelessly to impart the message that no matter what is said about a woman’s physical form or how she chooses to use it, a woman’s body is her only true home, and innately worthy of self-appreciation. Through her work, Jada hopes to inspire women to reclaim their bodies and develop a sense of sexual agency.
