Massage Therapist
Cartier Tejada, L.M.T., C.P.M.T.
Born and raised in Reading, PA, I spent my early years in South Florida, where I completed grade school. During my time as a wrestler, I discovered my passion for massage therapy by practicing on classmates and teammates.
This self-taught experience sparked a vision — one that could improve both my life and the well-being of others.
In 2019, I graduated from BTI with a specialization in full-body therapeutic massage before the program was discontinued the following year.
Throughout my career, I have expanded my expertise with training in prenatal, oncology, and lymphatic drainage massage. I have also incorporated various massage “desserts” — thoughtful finishing touches designed to enhance relaxation and create a deeply fulfilling experience for my clients. When I am not working, I enjoy spending time with my family.
