James Castillo


Ranging from physical to emotional health, from mental wellness to spiritual awakenings, from higher self guidance to grounding deeper into the body, I focus on helping clients find the flow of being and feeling their best self. I achieve this reflexology, reiki, life coaching, and guided meditations. First and foremost I always do my best to alleviate the physical body from discomfort. Personally I strive to grow through deeply healing of past traumas with self love while empowering others to do the same. Health starts with the awareness of self in conjunction with support from others to feeling better.
