5/5

Rebecca Shaw is empathetic, compassionate and highly knowledgeable regarding mental health. She provides such a higher level of care than most other providers and you will see this after the first visit. I cannot recommend Rebecca Shaw highly enough.

Review by Davy ***** February 15, 2026

5/5

Rebecca Shaw is unlike any mental health professional. Rebecca is extremely knowledgeable and helps people and empowers them to change their lives with her help. Next to her knowledge is the empathy she feels for people in distress or those feeling hopeless because of their issues. Rebecca listens to the person speak and actively listens to her clients.
