Obsessive-compulsive disorder therapists & psychiatrists in Chelmsford, MA

I’m Angela, a dedicated and empathetic Psychiatric Nurse Practitioner with extensive experience providing comprehensive mental health care. I work with individuals facing a wide range of challenges, including anxiety, depression, ADHD, substance use, and sleep disorders, as well as life transitions related to relationships, career, and personal growth. My focus is on creating a safe, non-judgmental space where every client feels heard and empowered.

My philosophy is very Jungian-based. I offer a masculine perspective to help those in learning about how to help relate to themselves better and then offer better relationships with others. My work is centered on the truth that when we see reality we are set free. The matrix keeps you stuck and enslaved. My mission is to help people free themselves so they can connect to their true nature and feel more fulfilled. I use health, nature, sexuality, and spirit to help others.

I am a board-certified Psychiatric Nurse Practitioner in Massachusetts. I offer comprehensive treatment combining medication with lifestyle and behavioral interventions. I help adult clients manage conditions such as depression, anxiety, OCD, bipolar disorder, psychotic disorders and substance use disorder. I also specialize in helping women navigate the peri and postpartum periods. I use evidence-based treatments that consider the client’s biological, psychological, spiritual, and social needs.

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.

I received my master’s degree from Columbia University in the City of New York and am an independently licensed Clinical Social Worker in Rhode Island and Massachusetts, with over 25 years of clinical experience. I would describe myself as energetic, empathic, and positive, with a good sense of humor. I believe in a client-centered approach and am committed to meeting my clients where they are in their lives. I am fluent in English, Mandarin Chinese, and Taiwanese.

My work centers on women’s wellness, with a focus on supporting women navigating ADHD, ASD, chronic stress, anxiety, nervous system dysregulation, and life transitions. Through working with a diverse range of clients, I’ve found that many women move through life feeling overwhelmed, disconnected from themselves, and stuck in survival mode.

With over 15 years of nursing experience, my passion for psychiatry began early in my nursing career as I witnessed patients transform their lives through healing, self-discovery, and resilience. It is profoundly humbling meeting someone at their lowest point and having the privilege of walking alongside them as they do the work to become their best selves.

I work with adults ages 18 to 60 from all walks of life, with a special focus on individuals who are often overlooked, misunderstood, or silently struggling. Many of the people I work with appear “put together” on the outside—successful, dependable, and strong—while internally feeling overwhelmed, exhausted, or barely holding it together.

I was born and raised in Boston, Massachusetts, to immigrant parents from Haiti, and my cultural background plays an important role in who I am as a provider. Being deeply connected to both Haitian and American cultures has given me a broad perspective and a deep appreciation for cultural identity, family systems, and the shared human experience. At the core, struggle looks very similar across cultures—and everyone deserves care that is respectful, culturally responsive, and compassionate.

Dr. Annet Kabuusu Mukasa is committed to empowering individuals on their journey to mental wellness by providing compassionate, judgment-free care. Clients need a provider who truly listens, understands, and integrates both evidence-based practices and holistic wellness into their care plan & desire a safe, supportive, and nonjudgmental space to heal and grow & don’t want to feel alone in their struggles; they need a provider who will walk alongside them with empathy and expertise.
