Welcome! I’m Dr. Alysia Sierra, a clinical psychologist with nearly 10 years in private practice. I am also a certified mindfulness meditation teacher. Areas of expertise include anxiety disorders, PTSD & attachment trauma; relationship struggles; perfectionism and codependency; imposter syndrome and burnout; substance use disorders; OCD. I have extensive expertise working with: high achievers, healthcare providers, first responders, athletes/performing artists, parents who feel stuck.
I specialize in medication management in treating mood, anxiety, psychotic, and substance use disorders. In the past, I worked as an RN in a dual diagnosis inpatient psychiatric unit. Recently, I have working in an outpatient private practice.
I'm a psychiatric nurse practitioner in Maryland with a background in both medication management and therapy — and I believe the best care happens when we tailor it to you. I specialize in anxiety, ADHD, and depression, and I work with patients who want a provider who actually listens before deciding anything. Many of the people I see found me through their community — they wanted someone they could trust, who'd take the time to get to know them. My approach is warm and direct: I'll tell you exactly what I'm thinking and make sure every session reflects where you are right now.
