Obsessive-compulsive disorder therapists & psychiatrists in Chelmsford, MA

Hi, I’m Tina Chen, a Psychiatric Mental Health Nurse Practitioner dedicated to helping clients feel their best. I specialize in treating depression, anxiety, and ADHD, and I combine medication management with practical tools from CBT and positive psychology. With advanced training from California Baptist University and National University, I focus on creating a supportive, collaborative space where you can build confidence, resilience, and balance in your everyday life.

My name is Roselyn Kwenda, and I am a board-certified Psychiatric Mental Health Nurse Practitioner. I earned my Bachelor of Science in Nursing from University of Massachusetts- Lowell in 2004 and my Master of Science in Nursing from University of Texas- Arlington in 2016. I have extensive experience in both inpatient and outpatient psychiatric settings, which allows me to support individuals across a wide range of mental health needs.

I work with clients who are ready to try something different — or who've tried talk therapy before and felt like something was still stuck.

I specialize in trauma, anxiety, depression, PTSD, OCD, eating concerns, and emotional regulation. I'm trained in EMDR, which is particularly effective for trauma and PTSD — it helps process difficult memories in a way that doesn't require you to re-live every detail out loud. For clients who connect better through creativity than conversation, I also offer art therapy as part of our work together.

I work with adolescents and adults across Western Massachusetts via telehealth, with some of the most flexible scheduling in the area — mornings, evenings, and weekends available.

If you’re looking for a safe, supportive space to work through substance use, mental health concerns, trauma, or a major life transition, I’m here to help. I’m a bilingual Licensed Alcohol and Drug Counselor I (LADC I) who supports adolescents, adults, and families in English and Spanish. I also support clients navigating anxiety, depression, stress, emotional regulation, relationships, recovery, and other personal challenges. My goal is to help you feel heard, respected, and supported without judgment.

Come and start your journey towards a better life. I will help you develop resilience and strengthen your inner core. I will work with you to develop problem solving skills, and learn effective communication skills. I am an empathetic listener with over 10 years of experience in this field.

If you’re feeling anxious, overwhelmed, depressed, stuck, or worn down by stress, trauma, relationships, or health concerns, therapy can help you find a clearer path forward. I’m a licensed psychologist who works with adults, with clinical and academic experience at Massachusetts General Hospital and Harvard Medical School. My style is warm, practical, and evidence-based, while always tailored to you as a person.

Hi! Thanks for checking out my profile! My name is Mike and I am glad you're here!

I received my masters degree in counseling from Fitchburg State University in 2017. After graduating, I started my career as a trauma-informed in home family therapist wherein I worked primarily with children, adolescents, and their caregivers teaching communication skills, coping strategies, addressing safety concerns, and working to improve stability in a home environment. Since 2022 I have worked as an outpatient counselor working with a range of clients from ages 6 to adult. I love working with a variety of clients, and focus especially on treating anxiety, depression, ADHD, and identity.
