English
| Español At Firefly Wellness, we work with children, teens, & adults who feel overwhelmed, stuck, disconnected, or unsure how to move forward. Many are navigating anxiety, depression, trauma, ADHD-related challenges, grief, relationship difficulties, school stress, or major life transitions. We provide integrated care that combines psychotherapy & psychiatric expertise when appropriate, allowing for a more complete understanding of emotional, behavioral, and biological factors. Treatment is individualized & grounded in evidence-based approaches, creative interventions, & practical coping strategies that support meaningful & lasting change.
At Firefly Wellness, we provide integrated mental health care that includes psychotherapy and, when appropriate, medication management and ADHD assessment tools such as BrainCheck or TOVA. We specialize in anxiety, depression, trauma, emotional regulation, and life transitions, using CBT, ACT, mindfulness, and expressive approaches.
Life can feel overwhelming, especially when you’ve been trying to manage everything on your own. We offer a supportive, nonjudgmental space where you can feel understood and supported as a whole person. When you’re ready, we would be honored to walk alongside you in your healing and growth.
