PMHNP, 2 years of experience
Hi, I’m Derek Terrell, PMHNP-BC and a graduate of Regis College. I specialize in diagnosing and treating mental health conditions affecting adults and adolescents. My special interests include working with professionals, minority groups, LGBTQ+, those that feel "othered", and providing 2nd opinions. I use a warm and empathic approach to create collaborative partnerships with my patients so that psychiatric concerns can be addressed from a shared perspective. I place a strong emphasis on psychoeducation by helping patients understand their diagnoses and management options so that they can make informed decisions about their health. My practice is rooted in a blend of supportive, client-centered, and insight-oriented therapy, ensuring a holistic approach tailored to your individual needs. Our appointments will never feel rushed. I strive to work with clients to explore their emotions, understand their experiences, and develop practical strategies for managing their mental health needs.
During your intake, I will work with you to develop a comprehensive treatment plan. If medication is started, you can always expect to understand the reason medication was started and potential side effects. In therapy sessions, you can expect to feel validated and supported but also gain tools and strategies to put into action in between visits.
I specialize in treating ADHD, Anxiety, Depression, PTSD, & Substance Use Disorders. I prefer to keep my clients engaged with treatment by regularly checking in with them, assigning therapeutic homework, and by setting clear and realistic expectations for treatment, so that they know exactly how I make the recommendations that I do, along with what they can expect from medications and/or therapy.
With over 25 years in psychiatry, I have worked in various settings including inpatient (acute/chronic), emergency, detox, IOP/PHP, outpatient & substance use. I specialize in treating adults, teens and families in crisis. I'm licensed in both NY and MA... so tell me, how I can help you today?
