Shawn Rodrigues, LPC

EAGALA Certified Professional since 2006


Shawn is a Licensed Professional Counselor and is the founder and clinical director of The Heart of the Matter, PLLC. Soon after realizing that she never belonged in an office setting, she found herself with a terribly abused horse named Boise who was afraid of people, life, and the world in general. As she nurtured Boise back to mental and physical health, she found herself becoming a better therapist – more attune and empathic to the needs of her clients, better able to guide them in processing their trauma  – and so the search began to find others of like mind and practice. She found EAGALA and The Heart of the Matter was born. Shawn is certified as a mental health professional and equine specialist in The EAGALA Model and is the local Eagala networking coordinator.
