Bipolar disorder therapists & psychiatrists in Massachusetts

My name is J.J. Mull -- I'm a clinical social worker and therapist in private practice. I trained and Smith College School for Social Work and received advanced training in psychoanalytic treatment at Cambridge Health Alliance through Harvard Department of Psychiatry. Since finishing my training, I have worked in a wide range of settings with people struggling with anxiety, depression, suicidal thoughts, substance use disorders, significant trauma, and many other issues. In addition to my clinical work, I am a writer, poet, and researcher and have been a professor in the Masters in Social Work program at Smith College for 4 years.

I have a unique professional background that includes working extensively with refugee and immigrant populations in a variety of settings, community based work serving youth, and crisis response. I grew up outside of San Francisco and moved around from state to state until I ended up in Boston. The diversity of my experiences and environments have shown me as much about the complexity of people as it has the beautiful simplicity that everyone shares a need (and deserves!) to be listened to, believed in, and safe to express how they feel.

As a Master's level therapist(MSW) and Licensed Alcohol & Drug Counselor I(LADC I) with 20 years of experience treating substance use disorders, I understand the anguish addiction causes. I treat substance addictions and mental health issues such as anxiety, depression, obsessive compulsive disorder, bipolar disorder, personality disorders and other addictions such as nicotine, gambling & gaming. You decide your level of recovery. No pressure. Questions? Please ask me!

I believe that meaningful change begins with feeling heard, supported, and empowered. I work collaboratively with clients to identify practical solutions, build on their strengths, and develop the tools needed to navigate life's challenges with greater confidence.

I enjoy working with clients who are ready to challenge themselves, explore new perspectives, and actively engage in the therapeutic process. Whether you're navigating anxiety, trauma, life transitions, or other personal struggles, I strive to create a supportive, nonjudgmental space where lasting growth and healing can take place.

I’m a board-certified Psychiatric Mental Health and Adult Gerontology Nurse Practitioner with advanced training in diagnosing and treating mental health as well as medical conditions across the lifespan. I earned my graduate degree in psychiatric nursing and have worked in both inpatient and outpatient settings, giving me a broad perspective on mental health care. I specialize in treating depression, anxiety, bipolar disorder, trauma-related conditions, and ADHD. I work with adults and adolescents, and I’m experienced in supporting individuals navigating different mental health conditions.

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.
