Text the office to schedule your new patient appointment: 978-285-9187 My ideal client is someone who feels overwhelmed by anxiety, ADHD, mood changes, or past trauma and is ready to explore support. They may be navigating school, work, parenting, or relationships and want to feel more in control, focused, and emotionally balanced. They’re looking for a provider who listens, offers clear guidance, and works collaboratively to develop a plan that fits their life. Balanced Chemistry is owned and founded by Antoinette Mailloux, PMHNP-BC, who also serves as its solo practitioner.
I specialize in treating ADHD, anxiety, depression, and trauma across the lifespan. I offer medication management, supportive therapy, and education tailored to your unique needs. My goal is to help you feel understood, find relief, and build skills for long-term emotional well-being.
Seeking help can feel overwhelming, but you don’t have to navigate it alone. I’m here to listen, support, and work with you at your pace. Whether you're new to mental health care or returning to it, I welcome you to reach out and take that first step toward feeling better.
