I am a Licensed Marriage and Family Therapist working with individuals, couples, and families.

I work with relationship challenges, anxiety, depression, trauma, parenting, maternal mental health, and life transitions.

My training includes EMDR, DBT, the Gottman Method, and ketamine-assisted psychotherapy.

I am a bilingual, Spanish-speaking Licensed Clinical Social Worker with over 20 years of experience.

I graduated from Fordham University Graduate School of Social Services. I have a certification in Breath Coaching, Mindfulness, Cognitive Behavioral Therapy, Trauma Informed Yoga in my practice and actively integrate these wellness practices in our sessions.

The core of my work has been to help people find solutions that work, to problems that prevent them from moving forward and living satisfying lives and relationships. I help people who feel stuck, to overcome life’s challenges, regain control of their lives and become the managers of their own self. Over the last 17 years I have been working with adults, teenagers and children from different cultures both in the US and overseas. Through my specialization and experience in severe and persistent mental illness I help people tackle emotional and communication difficulties that interfere with their relationships with friends, family

and the workplace. In my clinical work, I use evidence based psychotherapeutic approaches that have been proven effective through time. In a compassionate, and supportive environment I help people deal with a variety of problems like anxiety, trauma, obsessive compulsive disorder, depression, bipolar disorder, psychotic disorders, personality disorders,

emotional, relationship issues and divorce. I have extensive experience working with veterans, college students, substance abuse and LGBD individuals. In addition to individual therapy I do parent consultations for children and teenagers.

As a non-binary therapist, I am committed to providing a safe, welcoming space for individuals of all identities. My approach is warm and collaborative, ensuring that every person I work with feels seen, respected, and empowered. I specialize in working with both adolescents and adults, supporting them through the unique challenges of life and growth.

Hi, I'm Jean-Jeffrey Marcellus, DNP, PMHNP-BC, AGNP-BC, a board-certified Psychiatric Mental Health Nurse Practitioner with over 19 years of healthcare experience. I provide compassionate, evidence-based care for adults experiencing ADHD, anxiety, depression, insomnia, and substance use disorders.

I specialize in Medication-Assisted Treatment (MAT) for alcohol, opioid, benzodiazepine, kratom, and prescription medication dependence. My approach is collaborative and personalized, focusing on creating treatment plans that support each individual's goals, recovery, and overall well-being.

I offer both in-person and telehealth appointments, providing a welcoming, judgment-free environment where patients feel heard, respected, and empowered. I am committed to delivering culturally responsive care and making high-quality mental health services accessible to individuals from diverse backgrounds.

What I want clients to know about me is that I am not the kind of therapist who will just sit back, nod, and ask, “How does that make you feel?” I am warm, honest, direct, and very involved in the work we do together.

My strongest area of work is relationship and family dynamics. I help individuals, couples, and families understand the patterns that create conflict, distance, resentment, poor communication, and emotional disconnection. Many of my clients come to me feeling unheard, disrespected, emotionally exhausted, or unsure of how to move forward in an important relationship.

I also work with people who grew up in difficult or dysfunctional family environments and are now recognizing how those experiences may still be affecting their boundaries, relationships, parenting, self-worth, and emotional responses. I help clients understand not only what is happening, but how the pattern developed and what they can begin doing differently.

I believe insight is important, but insight alone is not enough. I want therapy to help you connect the dots and develop practical ways to communicate, set boundaries, manage conflict, and respond differently. I will support you, but I will also challenge you when I believe you are minimizing your needs, repeating unhealthy patterns, or avoiding something important.

I am not here to judge you, label the people in your life, or tell you what decisions to make. My role is to help you see things more clearly, understand what is within your control, and feel more confident in how you choose to move forward.

In addition to relationship and family concerns, I also work with anxiety, ADHD, emotional overwhelm, life transitions, and the impact these challenges can have on everyday functioning and relationships.

I am a Double Board-Certified nurse practitioner specializing in psychiatric mental health and family health. As a dedicated psychiatric nurse practitioner, I use an integrative and holistic approach to mental health. As a family nurse practitioner, I take into consideration how physical health impacts mood and relationships. I employ evidence-based medication management. Together, we can pinpoint what's causing you stress and navigate towards a balanced state. I employ brief supportive psychotherapy in every session to help patients manage their emotions, particularly those dealing with chronic illnesses or experiencing high levels of stress. By offering empathy and validation, I aim to strengthen coping mechanisms, boost resilience, and enhance overall mental well-being.
