I’m a board-certified Psychiatric Mental Health Nurse Practitioner (PMHNP-BC) dedicated to providing compassionate, evidence-based mental health care for individuals navigating life’s challenges. My clinical background spans addiction recovery, mood and anxiety disorders, trauma, ADHD, and women’s mental health.
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.

Licensed Independent Clinical Social Worker | Certified Dementia Practitioner
Boston, MA | In-Person & Telehealth Sessions
I am a Licensed Independent Clinical Social Worker (LICSW) and Certified Dementia Practitioner (CDP) with more than two decades of clinical experience helping adults navigate complex emotional, relational, and medical challenges. I hold a Master’s in Clinical Social Work from Boston College and have dedicated my career to providing thoughtful, evidence-based care rooted in authenticity, compassion, and the belief that genuine change is possible at every stage of life.
My areas of specialization include anxiety, depression, trauma, chronic pain, medical conditions, LGBTQ+ identity and relationships, grief and loss, end-of-life issues, and advanced care planning. My integrative approach draws from Acceptance and Commitment Therapy (ACT), Cognitive Behavioral Therapy (CBT), Solution-Focused Therapy, and a Humanistic framework. I believe that movement is medicine, and that healing emerges through the mind–body connection — where awareness, purpose, and action intersect.
As a gay clinician, I am deeply committed to creating an affirming, inclusive space where clients can explore identity, relationships, and resilience with honesty and respect. I strive to help each person cultivate balance, clarity, and a renewed sense of possibility in their lives.
Whether you're in the middle of something difficult or just know that something needs to change, this is a good place to start. You deserve a space where you feel truly understood, and that's exactly what therapy here is designed to offer.
I work with individuals facing anxiety, depression, substance use, problem gambling, and those who simply feel stuck or uncertain about their next step. Together, we'll work to uncover what's been holding you back and build toward the life you're looking for.
With a background in athletics and mental performance, I bring a unique perspective to this work, especially for those navigating pressure, confidence, identity, and personal growth.
I do Individual, Couples, Family, and Group Therapy. I currently facilitate a Bereavement Group which meets at my Brookline office every Saturday from 2-4pm. I also run groups for substance abuse, depression and anxiety. In addition, I have a lot of experience counseling children of all ages. I am a firm believer in strength-based psychotherapy.
I offer Psychoanalytic Psychotherapy to individuals seeking a deeper understanding of self. I help people build skills to overcome anxiety, depression and emotional overwhelm. I offer training in mindfulness, which emphasizes the importance of presence and curiosity in the healing process.
I have deep empathy and insight into exploring life’s deepest questions. Clients gain confidence and a sense of improved well-being by coming to understand themselves in a comfortable therapeutic setting. I work with diverse populations and clients beginning at young adulthood.
I’m a Licensed Clinical Social Worker licensed in Florida, New Jersey, Iowa, and Massachusetts, with several years of experience supporting individuals through trauma, anxiety, depression, and life transitions. I earned my Master’s in Social Work and have since worked in both residential and outpatient settings, helping adults navigate complex emotional experiences and build lasting resilience.
I’m trained in EMDR therapy and integrate evidence-based approaches like CBT, DBT, and mindfulness to tailor treatment to each client’s unique needs and goals. My style is warm, compassionate, and nonjudgmental, creating a space where you can safely explore your thoughts, emotions, and experiences.
I’m passionate about helping people reconnect with themselves, heal from the past, and move forward with greater clarity, confidence, and self-compassion.
With 165+ reviews and a 4.96 rating on Zocdoc, I have specialized in advanced medication management for complex, treatment-resistant conditions. I utilize a neurobiological approach that focuses on frontal lobe/executive functioning, nervous system dysregulation, and neurotransmitter systems to diagnose and treat various concerns - ADHD/executive dysfunction, OCD, trauma/C-PTSD, high-masking autism, personality profiles, and cases where standard medication treatments have failed. While I specialize in clinical complexity, I bring that same deep, careful attention to treating anxiety, depression, and clients starting medication for the first time.
I’m a board-certified Psychiatric-Mental Health Nurse Practitioner with a background in pharmacy, giving me a well-rounded perspective on mental health care. I work primarily with children, adolescents, and young adults, while also supporting older adults. My practice is rooted in compassion, advocacy, and respect for each person’s unique journey.
I am at my best when I am a guide for others. I start by listening and developing understanding of who you are, what you value, and where you struggle. I will help you to find your way back to yourself and develop the trust you need in yourself to live your best life. I use an approach that is very collaborative offering tools and resources, but assisting you to choose your own direction.
We all struggle at times, especially in the way we live these days. I can help you understand how and why you may be feeling overwhelmed, stuck, or disconnected and develop strategies to move through this to a happier, more grounded, and more confident version of yourself.


Headway makes it easier to find support for overcoming addiction — from finding the right provider, to understanding costs, to scheduling with ease.
Finding addiction therapists in Lexington starts with understanding the type of support you want. Addiction care can address alcohol use, substance use, compulsive behaviors, relapse prevention, and co-occurring concerns like anxiety, depression, or trauma. As you compare therapists, look for training and listed specialties that match your needs, such as motivational interviewing, cognitive behavioral therapy for substance use, harm reduction, or coordination with medication-assisted care when a prescriber is part of your care team.
Lexington has a smaller local therapist market than nearby Boston or Cambridge, so virtual care can expand your options while keeping access close to home. As you narrow your search, consider appointment availability, whether the therapist is accepting new patients, and the style of care described in their profile. A therapist’s bio can help you see whether they take a nonjudgmental approach, have experience with harm reduction frameworks, and describe how they support people through changes that may not follow a straight path.
Therapy in Lexington can be a significant investment without insurance. Using in-network insurance is one of the most reliable ways to reduce session costs and understand your out-of-pocket estimate before booking. Headway helps you compare addiction therapists who accept a wide range of insurance plans, review bios, check availability, and book directly when you’re ready.
If you or someone you know is experiencing severe withdrawal symptoms — especially from alcohol or benzodiazepines — talk to a medical provider or seek emergency care before starting outpatient therapy.
