Hi, my name is Rae and I am a Licensed Marriage and Family Therapist.

I work under the belief that big emotions and big reactions are not a sign that something is “wrong” with you, but rather are healthy signals seeking respect and attention to guide you toward your true self. However, many of us have heard or come to believe that we're "too much" throughout our lives—too emotional, too challenging, too overwhelming, or too far gone to deserve the things, relationships, and lives we long for. This messaging can lead to difficulties setting boundaries, fear of independence, or choosing isolation to avoid feelings of shame and disappointment when our needs go unmet.
