Trauma and PTSD therapists & psychiatrists in Chelmsford, MA

As a licensed substance use and addiction counselor, I believe that recovery is not a one-size-fits-all journey—it’s a deeply personal process that deserves compassion, respect, and hope. Every individual’s story is unique, and so are the reasons behind their struggles with substance use. My approach is rooted in the belief that healing happens when people feel truly seen, heard, and supported without judgment. I view my role not as someone who tells clients what recovery “should” look like, but as a guide who helps them discover what recovery means for them.

I’m Sean Bourgeoise, a licensed therapist with a Master’s in Psychology. I specialize in helping adults and young professionals work through problem gambling, substance use, and anxiety. My style is supportive, practical, and focused on helping you build insight and create meaningful change.

I have always known I wanted to be a therapist. From a young age I was empathic, patient, validating, comforting, flexible, and trustworthy. I believe that these were attributes that my friends and family seek me out for advice or to vent.

I studied psychology at Ithaca College and then worked for 4 years in foster care and group homes in NJ and NYC. Then, I moved to Boston and got my masters in mental health counseling at UMass Boston. Since graduating, I have worked in a wide variety of mental health environments; programs, schools, community based mental health, and virtual therapy platforms.

I am someone who is passionate about helping others and making everyone I meet feel heard, seen, and empowered.

I'm a nurse practitioner with six years of experience across inpatient, partial hospitalization, and outpatient psychiatric settings. I specialize in addiction and substance use, depression, and general psychiatry — working exclusively with adults. After years of high-paced clinical work, I built a telehealth practice designed around real life: I see patients evenings and Saturday mornings, so quality psychiatric care doesn't have to compete with your workday. I take a practical, no-nonsense approach — focused on what actually helps you move forward.

Hi! I'm Bryanna, a board-certified psychiatric nurse practitioner.

I help people who are good at holding it together and tired of doing it. I treat the worry that won't shut off, the flatness that makes everything feel like effort, the nights you can't sleep, and the chronic stress hiding underneath it all, in teens, young adults, and professionals. We talk about your sleep, your stress, and what's actually been going on, and build a plan together. Medication is one tool when it helps, not the whole plan. You don't need the right words to reach out. Just tell me what's been going on.

Outside of work, I'm a devoted dog mom and a professional starter of new hobbies. Currently, arts and crafts and chess.

Wellness isn't the absence of a diagnosis. You don't need the right words to reach out. Just tell me what's been going on.
