Beth Manzanares, Founder & Executive Director

Beth Manzanares, M.S., CCC-SLP (she/her) is the Executive Director of Gather and Grow Therapy Services. She also runs our sister organization and nonprofit, Inclusion on Purpose. Beth has been working with neurodivergent folx since 2009. As a neurodivergent therapist and sibling to an autistic brother, Beth has intentionally cultivated expertise in autism, ADHD, trauma-assumed practice, and self-determination. Her passion is teaming with and empowering people with all brains. 


As a speech-language pathologist, Beth understands the intricately woven relationship that binds communication, emotional regulation, sensory processing, and human behavior. She uses systematic analysis and continuous assessment to uncover unique learning style and meet people where they're at.


Beth founded Gather and Grow Therapy Services as a passion project stemming from a gap in high-quality service delivery across the age span. Beth currently spends most of her time in operations, but most enjoys program development, adventure-based therapy, and providing education on topics of neurodivergence and the intersection of language processing and emotional regulation.  

As an avid outdoors enthusiast, Beth and her husband, Dillon, spend as much time in the mountains as possible. Beth finds that nature and movement are some of the best teachers and particularly enjoys the challenge and lessons taught by rock climbing and yoga. She also loves relaxing with her family, snuggling her pup, Winnie, and carving out time for play and laughter.

Their clinical orientation is primarily based in Cognitive Behavioral Therapy, however, they believe therapy should be tailored to each individual’s unique learning and communication style.


That means for some folks, a therapy session may look like sitting face-to-face and talking, but for others it may include board games, art, worksheets, visuals, meditation, sitting on the floor, using a swing, or talking walks outside. Rhyan values all forms of communication and has experience using movement, writing, and art as tools for communicating and understanding emotions.
