Addiction therapists & psychiatrists in Brooklyn, NY

I am a clinical psychotherapist with almost a decade of experience working with couples and adults who want to better understand themselves, and work towards creating the lives and relationships they crave. I am passionate about helping people reconnect to themselves, their hopes, and their autonomy. I specialize in relational/marital challenges, anxiety, grief, addiction, eating disorders, and trauma.

I earned my PhD in Clinical Psychology in 2002. Having worked in healthcare and academic settings, I appreciate being part of a treatment team and am available to coordinate care with other providers when beneficial. Rather than see 'how many problems' a person may be facing... I see 'how many ways things can get better'. I value working with folks to see their puzzle from a different angle and to use tools to clarify, change and improve the picture.

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.

Reaching out is hard, especially if you've already tried therapy before and it didn't quite get you where you needed to go. I want you to know that doesn't mean something's wrong with you, it usually just means the approach wasn't the right fit. I've spent over a decade working with people carrying trauma and addiction, adults and teens both, and what I care about most is helping you feel truly understood, maybe for the first time, before we even get to the work of healing.

I view therapy as a collaborative process where clients are invited to make sense of their experiences in a way that feels authentic to them. Rather than directing the process, I focus on creating a supportive environment where individuals can speak openly, reflect at their own pace, and gain insight into their thoughts and emotions. In the midst of busy and often overwhelming daily life, having intentional time to pause and look inward can be a powerful part of personal growth.

Creating room for reflection can open the door to new perspectives and a deeper awareness of internal experiences. As clients begin to better understand their emotional responses and patterns, they often find greater clarity in how they relate to themselves and others. This increased awareness can support more intentional decision-making and help guide the next steps in their personal growth.

It's very difficult to be in stressful situations that can cause lots of anxiety and self-doubt. Perhaps you're looking for something more than advice from family and friends. If you're looking for a warm and inviting counseling atmosphere, I am eager to work with you to develop effective coping skills and a greater self-awareness to reach your full potential. Together, you and I can work to set goals that are appropriate and attainable for you, at your pace. For therapy to be effective for you, I work hard to build genuine and long lasting trust.

I have experience working with clients who have suffered from anxiety, depression, and marital issues. Additionally, I believe that cultural factors are critical to the way we navigate through life. I work hard to address cultural matters, to understand how these may impact our perception of the world.

Call me for a free consultation where we can discuss your needs and goals. For your convenience, I offer online counseling. También, ofrezco servicios en español. Llamame para discutir tus metas.

I believe prioritizing mental health is key to stability in life. I know there is a better world out there and people need the tools to connect with their upmost insight for mental well being. In this field I am always eager to research and find healing processes to tailor the need of each individual.

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.
